Reloader 19 or Imr 4350 for 300 Win Mag

[Lorne]

I am loading 180 grain interbonds in my 300 Win Mag.Any suggestions on which powder would be the best to try

 

[todbartell]

of the two, RL19 would be my choice, but I was given some IMR 4350 to load for a guy with some 180 Accubonds, and 70 grains made 2940 fps and good accuracy

personally Id try H4831 or H1000 first if it was *my* rifle

Yep. You CAN use a faster powder, but something like 4831's really more suitable

Powder choice

Try Reloder 22. its a classic 300 load with 180 gr. bullets.

Always had luck wiyh H4350

I'd try RL 22 first, then RL 19.

Take a look at Reloader 22 for 180s. Instant happiness in my current .300 Win Mag.

I have always used IMR 4350 in all of my 300 Wins and have had very good results. However it doesn't mean I shouldn't have tried Reloader 22. Just means its hard to train an old dog new tricks.
