38 special RMR bullet reloading data

[03RN]

I used 4.6grs of Winchester 231 which should be 861fps and 4.2grs of titegroup which should be 919fps according to their data.

With 231 I got 726fps out of my S&W 19 with a 4” barrel. When I did 4.3grs I got 622fps the book showed 809fps
Titegroup gave me 740fps with the same gun

I think I did try some without any crimp other than what you get with the seating die and it didn’t change anything.

My 147 gr data

I will try that and see what I get. Thanks man!

Hodgdons pressure barrel is 7.7 inches and is not identified as being vented. So their barrel is almost twice as long as yours and doesn't have a barrel/cylinder gap.

Well that makes more sense. I never did see what the barrel length was. Thank you sir.

I glad I asked. I was just worried that I was doing something off, I have never gotten anywhere close to the “max” charge before on a handgun.

What barrel length are you shooting from?

Hodgdon data is developed from a 7.7” barrel, which I’d bet is not vented.

What barrel length are you shooting from?

Hodgdon data is developed from a 7.7” barrel, which I’d bet is not vented.

It’s a Smith and Wesson model 19-9 with a 4 1/4” barrel. I also tried the load in my old 586 no dash with a 4” barrel. I’m sure it’s because of their test barrel length. I’m going to try and bump up my charge weight and see what I can get.

What is your OAL? I just purchased 4k RDS of 147. 2k plated and 2k polymer coated (Blue Bullets). I haven’t loaded .38 in a long time but getting back into it and will be shooting an ICORE state match this summer—so I’ll need to be sure to make PF. THX
