RE: .338 federal
Used it this year on elk, 185 grain Barnes-X - TSX. T/C Encore 338 Federal Barrel. Two shots, complete penetration and dumped my elk like a sack of rocks. Shot placement, premium bullet and practice all pay off. I was very pleased with this cartridge. Haven't done any hand loading for the 338 Federal yet but have enough brass now to play around a little with it.
I wanted to try it out on a mullie but work and weather got my deer hunt all wacked out.
The recoil on the 338 federal is very pleasant compared to the magnum's. I have used my 338 Win mag up til this year, when I switched and I don't anticipate going back to my 338 win mag anytime soon after the performance with the 338 Fed.
