Wally720 Posted January 13, 2019 Share Posted January 13, 2019 What's your go to powder for 357 magnum with a non-magnum primer? I'm wanting to develop something similar to the Buffalo Bore 180 gr hunting load, not using H110 / W296. Link to comment Share on other sites More sharing options...
Russ P Posted January 26, 2019 Share Posted January 26, 2019 I've used CFE Pistol in the past with non magnum primers. I use CFE Pistol 6.6 grains 158g XTP 1.580 OAL. I don't get anywhere near Buffalo Bore with this load. I don't have a chrono, but it seems like a fairly mid range load. I am thinking you need to go to H110 or W296 with Magnum primers to get the results you want. Others shoud chime in soon. 1 Link to comment Share on other sites More sharing options...
minervadoe Posted January 26, 2019 Share Posted January 26, 2019 (edited) Hogdon lists Lil' Gun as a powder that will propel a 180 grain .357 Magnum bullet faster than Win 296 or H110 http://www.hodgdonreloading.com/data/pistol H4227 gets close. Me? I just use AA #7 with 158 grain bullets. Not relevant to what you're doing. Edited January 26, 2019 by minervadoe Link to comment Share on other sites More sharing options...

After a trigger job on my GP100, I want to get away from CCI primers for this gun, due to primer ignition failures. This load is strictly for hunting, not something I shoot routinely. I use Unique for plinking, target loads. I know an option is to change the hammer spring back out to factory and keep my H110 - CCI magnum primer combination. I was really looking for a magnum powder with non mag primer combination ( preferably Federal) to produce a good hunting load. 1 Link to comment Share on other sites More sharing options...
Russ P Posted March 10, 2019 Share Posted March 10, 2019 Li'l gun still calls out for WSM primer Link to comment Share on other sites More sharing options...
Highspeedlane Posted March 22, 2019 Share Posted March 22, 2019 (edited) I would be looking in the direction of Lil Gun too. Not sure about using non-magnum primers though. Generally, slow burning powders that take up most of the case volume need a magnum primer for uniform and consistent ignition. In 4 to 6" barrels, H110 and a magnum primer is my go-to.

dudel Posted May 29, 2019 Share Posted May 29, 2019 Alliant 2400 with regular primers work great in 357Mag. Link to comment Share on other sites More sharing options...
