Thread: Powder choice for 264gr gas check 38/55 boolit

    Powder choice for 264gr gas check 38/55 boolit

    I recently restored a vintage Savage Model 1895 in 38/55 cal. I have been seatching for the best handload. I have been trying a 264gr cast boolit with gas check and getting ok group of 2 1/4". I'm looking at trying a different powder...Reloader 7. My Lyman Cast Bullet Handbook shows a powder designated as Rx7....is that Alliant Reloader7 or Accurate No 7??? Looking at websites for both powder manufacturers offers no answer. Help!

    Rx7 is Reloder 7. I use that same bullet in a .38-55 Browning Traditional Hunter single shot. I didn't get great accuracy with Reloder 7, but it may be worth a try in your gun. I've gotten best accuracy in my rifle with the following powders: 5744, IMR4198, and H4895.

    +1 on what lotech said. My 'go-to' for duplication of BP ballistics in my 38-55 Highwall is 4198 (either IMR or H). A plain-based 275 grainer (old, old Ohaus mold) over 20.2 grains shoots to the same POA as with 50 gr of FFg.
