Shanghai Posted January 25, 2019 Share Posted January 25, 2019 I finally reloaded the last of my 158 grain LRNFP bullets and ready to start reloading 125 grains. My load for both rifle and pistol has been 2.8 grains of clays with an OAL of 1.475. It’s always performed without a hitch and had great knockdown power. With the new 125 grain LRNFP, I’m planning a load of 2.5 grains of clays and an OAL of 1.445. My concern is whether I will have any feed issues with my 73 Uberti (action by Cody). And if the 125 grain will have enough knockdown power for plates, etc. Should I increase the 1.445 OAL a bit and maybe go with 2.6 grains of clays? I don’t want to have two separate loads (knockdown load), but I’m open to that option. Link to comment Share on other sites More sharing options...
Tyrel Cody Posted January 25, 2019 Share Posted January 25, 2019 Well, I'd go up to 3gr of Clay's and get above the min recommend load. I'd also crimp outside the crimp groove and get the OAL closer to 1.50 My dos centavos. Link to comment Share on other sites More sharing options...
G W Wade Posted January 25, 2019 Share Posted January 25, 2019 I agree with Tyrel all the way. He uses the same load I do and I have never had a problem with ant knockdown targets GW Link to comment Share on other sites More sharing options...
Shanghai Posted January 25, 2019 Author Share Posted January 25, 2019 Tyrel, that’s more powder than I was using with the 158. Part of my reason for transitioning is reduced recoil. 3 grains seems high. But I will increase my OAL. My thanks. Link to comment Share on other sites More sharing options...

That Clays has to build some pressure to burn consistently, and I've had problems with 125's breaking loose before that pressure builds. Seems 158's stay put just a little longer. But a tighter crimp always solved the problem. Link to comment Share on other sites More sharing options...
Deadshot Dan Posted January 25, 2019 Share Posted January 25, 2019 Howdy Shanghai, I'm on board with Tyrel on going ta 3 gr on that load. As far as col, i run a cody rifle with a 125 tcfp and crimp in the groove which gives me a 1.445 and have never had feeding issuse's. If it worries ya load up a small batch and run em and see what happens. Link to comment Share on other sites More sharing options...
J-BAR #18287 Posted January 25, 2019 Share Posted January 25, 2019 Look at any loading data chart- heavier bullets use less powder because of inertia. Lighter bullets need more powder to keep pressure where it belongs. It is foolish to deviate from loading specs provided by the powder manufacturer. They know their products characteristics better than anyone. Please dont go off the chart; not worth the risk. Link to comment Share on other sites More sharing options...
Marshal Chance Morgun Posted January 25, 2019 Share Posted January 25, 2019 I have been using 2.7 gr. Clays in both pistol and rifle. 125gr RNFP for pistol, 147gr TC at 1.52." for rifle. Never had a problem with KDs with pistol or rifle. Load up a few and see how your rifle feeds. Link to comment Share on other sites More sharing options...

Oklahoma Dee Posted January 25, 2019 Share Posted January 25, 2019 I suggest you chronograph your loads and see where your landing in the power factor arena, also. A lighter bullet weight with a lesser amount of powder usually decreases the power factor. AMMUNITION COVENANTS Power Factors The minimum standard for center-fire ammunition used in all smokeless categories in all SASS matches, including State, Regional, National, International, and World Championship competitions is not less than a minimum power factor of 60 and no velocity may be less than 400 fps. Power factors can be calculated by multiplying the bullet weight (in grains) x the velocity (in feet per second) and then the resulting number divided by 1000.

Shanghai Posted January 25, 2019 Author Share Posted January 25, 2019 Appreciate the good counsel. I’ll stay within the guidelines, increase powder and COL. I’ll make sure my crimp is solid and make a batch to shoot before going to town on the press. Thank you all. Link to comment Share on other sites More sharing options...

Cowboy Junky Posted January 25, 2019 Share Posted January 25, 2019 I'm a lighter bullet more powder fan. 4 grains of Clean shot @ 105. I used 2.7 grains of Clays years ago before I learned you could go too light and in the winter I had inconsistent ignition. That was with a 125 as well....not the 105. The clubs you attend must have awesome knockdown targets because I would be scared to death to use those loads for the knock downs around here.

Cliff Hanger #3720LR Posted January 25, 2019 Share Posted January 25, 2019 The lighter bullet requires more velocity to meet the Power Factor. To meet the power factor of 60 the velocity of 158gr = 400'/sec = power factor of 63.20 . 125gr at 480'/sec = power factor of 60+. Why do lighter bullets need more powder? The lighter bullet has less bullet in the case. This cause more empty space in the case requiring more powder to build equal or more pressure before the bullet jumps. The lighter bullet will jump sooner than a heavier bullet causing the pressure to not built sufficiently to burn the powder completely. If you use the same powder charge in a 125gr rounds as a 158gr round, the 158gr rounds will product a higher velocity. As a commercial loader for 18 years, I suggest you start your 125gr using the same charge as your 158gr rounds. Chronograph your rounds and see if they meet the Power Factor velocity minimums.

Rye Miles #13621 Posted January 25, 2019 Share Posted January 25, 2019 I use 3.5 grs of Tite-Group with a 125 gr bullet. Works great for me!! I also think you should up the powder a bit! Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted January 25, 2019 Share Posted January 25, 2019 As someone who has been reloading for over 55+ yrs I say this. You will find variances from lot to lot of powder. Make sure you use a firm roll-crimp, and to 'zero' your scale to be sure the charge thrown is the real amount. I would suggest you load the 125's with at least 3.0gns.

Cheyenne Culpepper 32827 Posted January 25, 2019 Share Posted January 25, 2019 well, if you were shooting Palerider, then I cud see a concern about recoil,,, see avatar pic,,, not that I shoot those very often. usually use 3 of clays with 125 bullet, with heavy crimp in crimp groove Link to comment Share on other sites More sharing options...
Tully Mars Posted January 25, 2019 Share Posted January 25, 2019 Hey Shanghai, Slo Mo and myself use 3.0 grains of Clay's with 105, 125 and 158's with an OAL of 1.5" just as suggested by Tyrel above. All are the truncated cone. If it's less recoil you're looking for the 105's are perfect. We shoot 105's at most matches and carry 125 and 158's with us. The 105's will knock down most plate racks, but the larger targets on tombstone racks can be difficult. Typically we just load the 158's for KD's. If you want to try some I'll get you some.

Joe Cross, SASS #13848 L Posted January 25, 2019 Share Posted January 25, 2019 140 grain TCFP (plain lead or coated) and 3.0 grains of Hodgdon Clays for everything. COAL is 1.442 with a medium roll crimp in the crimp groove. Runs through both my 38 spl Marlin CBCs with no hitches or hiccups. Even my 357 cowboy limited likes 'em. The only time(s) I've failed to knock over a plate is....you guessed it...I missed! JC Link to comment Share on other sites More sharing options...
Church Key, SASS # 33713 Posted January 25, 2019 Share Posted January 25, 2019 As mentioned several times above, 2.5 grs. is well bellow the Clays minimum, as Lyman shows 2.9 as a starting load and an OAL of 1.450. I load 3.0 Clays at 1.440. Cody told me to use between 125-158 gr. bullets in my Codymatic 73. Has worked fine for 12 years. Recoil is not noticeable to me.

Church Key If you check the Hodgdon web site for loads, you will find they list Clays at 2.5 starting and 3.5 as Max for a 125 lead bullet. I've been shooting 2,5 clays with 125 RNFP for years. But I shoot 3.0 Clays 160 RNfP for plate racks and Texas star. Link to comment Share on other sites More sharing options...

Shanghai Posted January 25, 2019 Author Share Posted January 25, 2019 Wow. Great advice on loads and the dynamics of a smaller bullet. I’m pretty confident going forward now, but I’m wondering if I should have stocked up with truncated cone bullets. I stocked up with rnfp and hopefully they’ll cycle ok In my 73. But should I be thinking about TC with new bullet buys? Link to comment Share on other sites More sharing options...
Shanghai Posted January 25, 2019 Author Share Posted January 25, 2019 Yes, I’d like to reduce recoil with pistols. I’m clean with my rifle but too many misses with the pistol. It’s the main reason I’m changing to 125 after shooting 158 for so many years. I need to slow down and keep on the front sight and lower recoil should help. I think the two load option is best for me. I’ll stay with 158 for knockdowns and see how the 125 recoil feels for reduced recoil. Now I’m thinking 105s. Hey Tully, next time I see you if you have a few 105s I can try, I’d appreciate it. Thanks for the offer. And thanks to all on this forum for helping me through this bullet change. I’m a creature of habit so changing my old load is a big deal and you all have made me feel confident about it. Link to comment Share on other sites More sharing options...
Billy Boots, # 20282 LTG-Regulator Posted January 26, 2019 Share Posted January 26, 2019 2.9-3 gr Clays is good for me with 105, 125, 135, 147...coated Cimaron bullets. Your 125 is probably same design as most. I suggest to crimp just into lower edge of crimp groove making a probable OAL of 1.465" . Don't change seater setting for other bullets works for me, even if they do not have a crimp groove. I make default setting to the 105 to insure at least a 1.455" minimum OAL, then the 125 and other two weights take the same (but of course, may have slightly different, and longer, OAL reading). As mentioned 105 will have less pressure so may be somewhat sensitive in cold, and also a little dirtier to cases. For Sassy and I, 125s work great with 2.9-3.1 Clays. I use Federal 200 primers. I think you will like the change to 125s and find them good straight across board with pistol and rifle. You should rarely need the 158s. I like 105 for both R & P but in the rifle the dirtier burning 105 often presents a distracting residue in my face when ejecting case due to lack of pressure.

Springfield Slim SASS #24733 Posted January 26, 2019 Share Posted January 26, 2019 Use Snakebites and BP, that will slow you down if that's all you are trying to do. Seems to me a less recoiling gun will speed things up, otherwise, why do it? Using a lighter bullet won't make you gun any more accurate. Link to comment Share on other sites More sharing options...

Kirk James Posted January 28, 2019 Share Posted January 28, 2019 The three of us follow Tulley Mars post. The only difference is we use 147 knock downs for the large or hard to knock down plates, and 125 gr for most everything else in knock down plates. We also seat our rounds to 1.510 to 1.520 depending on how they feed in each rifle. 1.515 is a sure thing in all 3 of our rifles. We do reload over the top and seat our reload rounds for 1.425. I do suggest you follow Oklahoma Dee's advice and chronograph your pistols to ensure you are within the power factor. We set our powder throw at 3.0 and rounds are usually somewhere between 2.9 and 3.1 for Clays. This is our favorite powder. Link to comment Share on other sites More sharing options...
