Light or heavy bullets for 20” 338 win mag

[J_V_Berry]

I just got done cutting down the barrel for my Winchester m70 in 338 win mag, and installed an Alaska 360. Topped of with a night force 2-20. I will be hunting moose in Alaska with this rifle. I am not expecting to take a shot much over 300 yards. My question is bullet weight. Should I go a lighter bullet because of the shorter barrel? I have a handful of 225 grain and 250. I have loaded 250 for it previously because I found that the 225 fell behind the reloading bench and I forgot I had them.

I am using a 338 Sherman (338-06 improvedish) with a 22" barrel. I am using a 190 mono at 2950ish. It has been used on WT with a 175gr mono at 3200ish. Very impressive.

I think light and fast is the way to go with these shorties, expecially with your range limit of 300 yards.

A heavier and longer bullet will allow a more efficient powder burn in a short barrel because it puts up slightly more resistance at ignition. Hence you don't "lose" as much velocity.

I agree with Lite and Fast.
Around 180 to 225.
Varget, N-150-540 maybe H-4350.
My 2-cents.

And this will work.
