Home Forums Hunting & Shooting General Big Game 338-06 elk bullets

Here are the results from today's chronograph session:

56.0 gr. IMR-4350 2379 fps

57.0 gr. IMR-4350 2422 fps

58.0 gr IMR-4350 2469 fps

In my rifle that's about as far up as I want to go -- in fact I may back down to 57.5 grains. How the Jeffery, with its smaller case got 2500 fps isn't clear to me and I'm wondering that the actual speeds were on those old loads at 75 degrees.


Recoil with these 250s is stout -- more than a .300 Win Mag. with 180 grain loads.

Edit: Oh wait, I just checked and the case capacity of the .333 Jeffery is given variously as 84-86 grains vs the .338-06's 70 grains.
