Re: 338-300 WSM for a light elk rifle?

What are your guys thoughts on accuracy of the Accubomb vs the Berger?

And from my own experience the barnes I'm shooting just don't expand enough. I've had great expansion out of the Accubonds, and it sounds like a 250 elite hunter would open up just fine too... so it comes down to accuracy. Thoughts?

If I can get ahold of some berger 250's I'll probably be able to shoot them the first weekend in December. Will let you know how it goes.

I re ran the numbers with the 230 Target Hybrid and at 800 the velocity and energy are within 60 fps and ft lbs between the 300 and 338, elevations in within a 1/10th MOA and windage favors the 230 by a couple 1/10ths.
Very close to each other at the same starting velocity, but if your buddy is getting 2725 from a 22in barrel seated deep going to a long action 26in barrel a guy may be surprised at the velocity gain!!!

I've had exceptional success getting Bergers to shoot, I had a rocky start but I've loaded so many now that I can usually get them dialed in very quick, the last one only took 12 rounds and we had found the load, loaded up a bunch and punished rocks out as far as the shooter was capable. But some guns just flat reject all common sense and won't shoot a certain bullet, I don't dwell on it just move to another bullet before wasting multiple boxes trying to force it to happen.

What brass are you guys using. I mashed up a couple 270wsm cases and seated some 300gr OTMs in the right position to be the same as a 250. I loaded them up in a Weatherby vanguard that i have around and they mag feed perfectly from the standard length mag. Recoil numbers are very close to the 300 Wby which is acceptable but I would brake it so I can easily go from braked to non depending on the terrain.

I am using Nosler 325wsm brass. The Win brass I started with was all over the place. From loose primer pockets to huge weight variations to large variations in neck wall thickness.
