Four posts down the page from yours.

You are already using probably the most common 7-08 powder. Varget works very very well.

Welcome to steelchickens by the way!! Looks like the welcome wagon kind of rolled right past you.

Welcome!

thx very much

In an 8 twist 3 groove barrel I use 37grs of varget...with a winchester primer. It will take up to 39 with some primer flattening....One doesn't need that. ( Winchester brass)....Norma brass or lapau limits one to about 38grs...the adventurous can try 39

I shoot both 175 gr. Hornady Interlock and Sierra SPBT. Loads that my guns prefer are 38.0 Varget.....37.0 RL-15.....43.0 I4350. The 4350 load is overall the best in accuracy and provides 100 fps. more for same pressure as the others.

IMR 4350...thank you. Cant wait to try it....

I've found 42gn x AR2209 to be very accurate. This is one of the Australian made Mulwex powders sold by Hodgdon in the States as H4350 I believe.
