Re: Alternative to H4350
I tried rs62 with 123gr amaxs.with rs data max load of 38.2grs and they were real slow at 2685fps to 2698fps.they must be 250fps slower than they can run.

Re: Alternative to H4350
Assuming that these are max loads and you can't load any higher, you'll have to move onto the energetic, double Base powders such as Reload Swiss RS60 or one of the Vihtavuori N5xx powders. These should get you a bit of extra velocity but the extra energy will result in faster barrel wear.
Re: Alternative to H4350
I only tried them.never pursued them.book data loads can be conservative.my 6.5x47 is zeroed for 140gr amaxs on 39grs of RS60 and they shot at 2835fps.only use them for a hunting load. The odd single shots.it doesn't go across the fields that often to worry about the RS60 killing the barrel.my McQueen's shooting will do that
