So, in my 8" twist 29" barrel with a throat roughly .220" long, and running whatever Hammer works, would I still need a fast powder?
I ask because this rifle works best with Retumbo and H50BMG. If I could get my hands on RE33 and US869 then that's what it would be fed.
Thinking of trying Hammers, not a huge fan of solids normally, but could be persuaded.
Looking at the above, a 9" twist 270 Bee and a 10" twist 300 RUM. Also have a 9" twist 338, but don't hear much mentioned in that cal with the Hammers. Thinking of doing another 375 with a 9" twst.
I guess I better read up on these hammers. Dunno if any will work in a 9.25" twist STW.
Cheers.
