Quiet Burp Posted September 21, 2021 Share Posted September 21, 2021 Is it ok to ask a reloading question? Please delete if inappropriate. I bought a Rossi lever action in ..357 it feeds .357's a lot better than .38s I use ADI AP50n 3.4gr for my .38 reloads and like it. Is it ok to put 3.4gr in a .357 case? Will more engine room in the case cause a problem? Will I need to up the powder charge for .357 0r am I Ok with the same .38 load? ADI (Australian Defense Industries) makes a lot of powder for the USA and is marketed under brands like Hodgen and I'm pretty sure that Hodgen International is the same as ADI AP50n Link to comment Share on other sites More sharing options...
Not Dead Ed Posted September 21, 2021 Share Posted September 21, 2021 For my old Henry (no it’s not my main match, it’s the backup’s backup) it likes only 357 cases, and my Rossi is happy with the 357’s too. I just load them with the same load and primer. some might suggest a magnum primer, but I haven’t had issues…. BTW I loaded with accurate 5 on them and Titegroup.

Rattlesnake Slim Posted September 21, 2021 Share Posted September 21, 2021 In a word, yes. The gunsmith that built my rifle told me that for the best, most reliable functioning, the headstamp on the brass should match what's stamped on the barrel. However, using .357 brass may not be magic. Most '92's are very length sensitive, and you may still have to tweak the overall cartridge length some. But starting with .357 brass puts you in the right spot. Link to comment Share on other sites More sharing options...
Sedalia Dave Posted September 22, 2021 Share Posted September 22, 2021 AP50N doesn't appear to have an equivalent Hodgdon powder. AS50N is equivalent to Hodgdon International. I would not use a 38 special charge in a 357 case without load data to back that up. Link to comment Share on other sites More sharing options...
Larsen E. Pettifogger, SASS #32933 Posted September 22, 2021 Share Posted September 22, 2021 "the headstamp on the brass should match what's stamped on the barrel." My barrel is stamped Made in Japan. Link to comment Share on other sites More sharing options...
Imis Twohofon,SASS # 46646 Posted September 22, 2021 Share Posted September 22, 2021 I load 3.0 gr of Shootersworld Cleanshot in both 38 and 357 cases for our rifles. One prefers 357 length for feeding and the other wont hold ten 357 length cartridges. Same bullet, same charge, same primer. I wouldnt do this for loads close to max but it works for cowboy just fine. Imis Link to comment Share on other sites More sharing options...
DeaconKC Posted September 22, 2021 Share Posted September 22, 2021 I had one of those Rossis like that. Try loading a 140+ grain bullet in the 38 Special cases, mine would run great with most 158 grainers, but HATED anything under 140 grains. Link to comment Share on other sites More sharing options...
WOLFY Posted September 22, 2021 Share Posted September 22, 2021 QB, what is max for your 38 spl load? Do you have access to magnum primers? ADI in Canada describes AP50N as medium density / medium-fast burn rate. Link to comment Share on other sites More sharing options...
Lazy Eeyour Posted September 22, 2021 Share Posted September 22, 2021 I would compare your load with 38 to 357. I would not go much below, if at all, the 357 starting load. Link to comment Share on other sites More sharing options...
Bison Bud Posted September 22, 2021 Share Posted September 22, 2021 Generally speaking, you should be okay with the .38 special load in .357 Mag brass unless the original .38 load is very light to start with. The extra volume in the .357 case does have an effect and a really light load may not completely burn, get really sooty, or even stick a bullet in the longer barrel. All in all, it would be good to check the .357 load data for your choice of powder and if you have to bump the charge up a bit to meet the minimum listed load, then I would recommend doing so.

The Original Lumpy Gritz Posted September 22, 2021 Share Posted September 22, 2021 Use a firm roll crimp to help with the powder burn OLG Link to comment Share on other sites More sharing options...
Snake-eye, SASS#45097 Posted September 22, 2021 Share Posted September 22, 2021 You may try this with the 38’s.. 125 gr RNFP Link to comment Share on other sites More sharing options...
Cliff Hanger #3720LR Posted September 22, 2021 Share Posted September 22, 2021 APN50, HP-38 and W231 are all on the ADI chart. Having manufactured new and reloaded ammunition for cas shooters for 18 years, I have used both HP 38 and W231. My load for 38 special and 357 magnum was the same powder charge. The length for 38 special was 1.54" and for the 357 magnum was 1.58". (using 125gr TC bullet) I also shoot Rossi 357 marked carbines. I have 8 of them and they all feed the 1.58" magnum ammunition without any problems. Any longer and problems could come up.

Loading .38's the .357 OAL is what most Rossi shooters do. What is the OAL of your .38's. I load 147 TC bullets to 1.52 inches. Works just fine in mine.

Is that definitely ok to have them sticking out that much? It will solve all my problems. And save me a lot of $ as Starline .357 brass is around 50c each.

Last Call Saul Posted September 23, 2021 Share Posted September 23, 2021 1.50+ oal in 38spl will feed it through 357 marked rifle Link to comment Share on other sites More sharing options...
Sedalia Dave Posted September 23, 2021 Share Posted September 23, 2021 My 92 will feed 125 gr LTC loaded in 38 special cases with an OAL anywhere between 1.505 to 1.510 The are crimped about 1/2 way between the crimp groove and the lube groove. I did all the action mods from Nate Kiowa Jones' video. Link to comment Share on other sites More sharing options...
