Paulo Pistolero Posted March 30, 2022 Share Posted March 30, 2022 Using a MEC 600 jr Mk5 loader with a loading bar for 1oz 8shot. The bushings used with approximate grains dropped of international clays. #23 bushing ≈ 18.3 grains #20 bushing ≈ 15.4 grains #19 bushing ≈ 12.8 grains #17 bushing ≈ 11.7 grains Asa Smith and I both shouldered each of these loads. The 18.3 and 15.4 loads both had some kick. Velocities around 1080 and a bit lower by Chrony brand chronometer. The 12.8 grain loads in the 900’s and felt pretty good on the shoulder. The 11.7 performed the best on the shoulder. Actually felt like Winchester AA 980fps. So there you have it. Yes if needed international clays can be used!! RIGHT ASA!!! So the test was productive and got to shoot with a great friend!! What a day!! Link to comment Share on other sites More sharing options...
Garrison Joe, SASS #60708 Posted March 30, 2022 Share Posted March 30, 2022 Well, what hulls, wad(s) used and what shot weight? Vital info if anyone else wants to try this. good luck, GJ Link to comment Share on other sites More sharing options...
Totes Magoats Posted March 30, 2022 Share Posted March 30, 2022 I'm betting you can go even lighter. We were working on a buckarette load using Trailboss in 12ga and it just worked 'ok' since she didn't have to knock over targets, but there was a need to use 2 powders (father had one load, daughter had another). So, we experimented with regular Clays and settled on 10.9 grains and 1oz of #7.5. We liked it so much, I still shoot that load today.

Paulo Pistolero Posted March 30, 2022 Author Share Posted March 30, 2022 Used Winchester 2 3/4 AA red and grey hulls. 1oz shot. With clay buster WAA 12SL Wads. Sorry got going and forgot some important information. Link to comment Share on other sites More sharing options...

I think I am satisfied at 11.7 grains. Turning 65 next month. As I get older and the old shoulder gets a bit more fragile I will test lighter loads.

Paulo Pistolero Posted March 30, 2022 Author Share Posted March 30, 2022 While testing the shotgun loads Asa and I took time to shoot my Kentucky flintlock rifle I assembled from a kit. Those flintlock rifles are fun to shoot. Makes you think about our founders fighting. Must have been mostly sword and butt of rifle because reloading isA CHORE!! BTW Asa nailed a small target dead on. The second video. That is quite a feat considering discharge delay!! IMG_3016.MOV IMG_3012.MOV Link to comment Share on other sites More sharing options...

Should be a micro second slower than a percussion rifle. Flintlocks in my experience don't like subs. FWIW Link to comment Share on other sites More sharing options...
The Original Lumpy Gritz Posted March 30, 2022 Share Posted March 30, 2022 OP, those MEC bushing powder weights, is that what you measured, or what MEC sez they'll throw? OLG Link to comment Share on other sites More sharing options...

I did not have 4f powder for the flash pan. We used a mortar and pestle to take 2f and make it finer. Was using triple seven powder. Link to comment Share on other sites More sharing options...

H. K. Uriah, SASS #74619 Posted March 30, 2022 Share Posted March 30, 2022 Everything I have read about Trailboss says not to use it for shotshells. Granted, I have often thought it would be nice to be able to do so, but there is no loading data, and when asked, Hodgdon says it's not suitable. I use Red Dot, for shotshells. My "classic" load that my Dad developed as a trap shooter was 16.4 grains of Red Dot in both Winchester AA's and Magtech all brass. Using 7.5 size shot, 1-1/8 ounces of it. Works great for trap. Recently, after reading some comments from others, I reduced the load to 10 grains and cut back to 1 ounce of shot. It takes down the take downs, reduces recoil a bit, and makes the powder last longer. I still use the "classic" load for trap. And these days, Trailboss is impossible to come by, and Hodgdon is rather cagy about when it will be made again. I have also been unable find any Red Dot for quite some time. I have found other powders, Win 231, that I use for most of my pistol powders, but I have not yet figured out what to use for shotshells if I can't find any Red Dot. Not done any research on a good powder for "rifle" cartridges that'll give me the mild recoil that Trailboss does. I'll cross that bridge when I come to it.

Roscoe Regulator Posted March 31, 2022 Share Posted March 31, 2022 Claybuster lists CB1118-12 (WAA12) as optimal for 1 oz. Those are rose colored. The grey CB1100-12 (WAA12SL) wad will load 7/8 or 1 oz but is listed as optimal for 7/8. You will save some shot if you try 7/8 oz. Link to comment Share on other sites More sharing options...
"Big Boston" Posted March 31, 2022 Share Posted March 31, 2022 MEC has a pretty inclusive bushing/powder chart. I've always found it necessary to measure the actual weight. I've never had to vary more than one bushing from the recommended though. Thanks for posting the chrono figures, it does show a fairly linear velocity curve. Bushing # Grains of Clays 10 8.3 11 8.8 12 9.3 12A 9.9 13 10.4 13A 11 14 11.6 15 12.2 16 12.9 17 13.5 18 14.2 19 14.8 20 15.5 21 16.2 22 17 23 17.7 24 18.4 25 19.2 26 19.7 27 20.8 Link to comment Share on other sites More sharing options...
