2017年4月20日 · I use HP-38 for many different loads in 32 long, 38 S&W and Special, 357 mag, 44 special and mild 44 mag, 45 ACP and 45 Colt. It's pretty versatile for just about anything. It is the same powder as Winchester 231, just different name. Meters well, burns clean and is about the same burn rate as Alliant's Unique.

2011年10月30日 · I'd like to get some advice on fine tuning a load for 38 special using HP-38 powder with Hornady dry lubricated 158gr LSWC. I recently finished a lot of 50 - in two batches. Everything came out very well, except that there was a LOT of smoke when either batch was fired. This was done at an inside range, with admittedly poor circulation.

2014年2月7日 · I use HP-38 to load major for mid length and long OAL. I am at 4.8gr @1.185 OAL with a Bayou 180 for a 5" Para I am shooting. I have loaded the same powder charge @1.140 for a Glock 35 and 22.

2018年4月5日 · HP-38 aka Win 231 was getting really hard to find for awhile. My favorite powder for .38 special and .45 auto. But when I first started reloading .45 , Red Dot was THE powder for .45 match loads. Dirty , but very accurate. The other downside is big flake powder does not meter thru powder measures as smooth as small flake or ball powders.

2024年4月11日 · This is in the appropriate forum (General Reloading, 9mm/.38). I have a ton of HP-38 so that is what I will be using until my supply is exhausted. I was just hoping that someone would post an approximate amount of grains to use with 147g coated round nose for Minor PF. I appreciate the information though !

2020年12月6日 · 9mm hp-38/w231 Handloading, Reloading, and Bullet Casting. HP-38 is an excellent powder for 9mm. Please take note that the only load for HP-38 and a 124-grain bullet is for a Berry's hollow-base round-nose bullet.

2012年7月28日 · For 230 GR lead Hodgdon recommends for HP-38 a max load of 5.3 GR, this is a pressure of 17,000 CUP. For a 200 max is 5.6. You may not be getting all of the powder burnt. These are very old lead bullets, what’s the condition of the lube on the bullets? Since you don’t know the age or manufacture of the bullets this could be reason.

2019年8月16日 · With 20 oz combined weight, my PCCs will cycle even lighter target loads (115 gr RMR FMJ with 4.6 gr W231/HP-38 or 4.0-4.2 gr Red Dot/Promo). For reference: - H1 buffer weighs 3.8 oz - H2 buffer weighs 4.6 oz - H3 buffer weighs 5.4 oz BTW, W231/HP-38 is temperature sensitive and Promo is reverse temperature sensitive.

2010年1月25日 · According to Mike Daley at Hodgdon, W231 and HP-38 are indeed the same powder. Winchester and Hodgdon both get the powder from the exact same OEM manufacturer. The only difference is the label on the bottle. That being the case, I do find the loading manuals that list different load data for the two powders hideously amusing.
