I know theres millions of threads already about powder choice..
I use H4895 for my .243 100gn BTSPs and it works well in that rifle.. I use H335 with 40gn BTs for my .223 and again it give wonderful results..
Now my .308 i am debating what to use.. Can anyone shine a light on 'fast burning' powders and 'slow burners'? Its a R700 PSS with a 22'' barrel.. Ive heard that with shorter barrels you should use faster powders etc.. I intend having a play with H4895 and H335 (if the book allows) to see what results i get.
I have been using PRVI partizan ammo with the heads replaced for 150gn Hornady SSTs and have found the optimum OAL and amount of PRVI powder. That combo is giving me 0.7MOA consistently but ive about used all of the rounds.
It would be nice to use one powder in everything but i would rather spend a bit of extra cash and find the sweet spot.
What was interesting with the load development for the .308 was that by seating the head on the rifling, the groups opened up to over MOA.
The other thing ive been thinking (seeing as ive pretty much used a box of 150gn SSTs is that aparently the R700 PSS .308 was designed around 168gn bullets, do you think its worth going for this weight or just stick with the 150gn SSTs?
So many options.. hmm.. Need some helpful advice and have turned to you guys! (hopefully Muir will point me in the right direction!!)
