Re: Anyone have a 7mm-.338 Lapua?

I was chatting with a guy at the range the other day. His bench rest rifle is a 7mm-338. He is shooting 180 gr berber hybrids at an mv of 3400 f/s. Sorry, I don't know more details than that. Well, he thought the barrel would be gone in 700-800 rounds, as I recall.

Re: Anyone have a 7mm-.338 Lapua?

I will get some photo's on here over the weekend, and a loaded round to.
As far as barrel life is concern, I spoke to Dave about just that.
He mentioned with proper care and 3 shots patterns and letting the barrel cool not taking that 4-5th shot. The barrel will have a long life.
Also 800 rounds for me at least with a rifle that is dead on for that one shot kill out in the field, that's a long time.
I keep my loads tight consistant and seldom shoot more than 5 shots just to sight in.

Here are some photo's of the the rifle and a loaded round next to a 264 Win Mag
I was able to get 3375-3400 FPS so far, Dave was able to achieve 3500, but he at a much higher altitude.

Common guys 250 shot barrel life are you kidding, I was hoping for just 75.

So far this is my test trget at 100 yards with the bullet seated 50 thousands off the lands. I've tried further down but not as good, slightly wider spread.

Would that not equate to the already commercially available 7mm Rem Ultra Mag?
Yes, the case dimensions are diferent however when comparing case capacity they would be very similar in volume, therefore similar in performance.

Steyr, your 100 percent correct the two round are very similar all around, the Lapua is just a bit faster and uses a bit more power.

But with that said, as I had discussed for some time with my gunsmith, the Lapua Brass is a much a better brass and holds up a lot longer life than the others when loading, and the fact that the bolt is still a 416 base, which always gives me room if I decide to change to a reg. Lapua 338 or what ever, its a matter of changing my barrel.
See I had the Bolt 1st. just was not sure if I really wanted a reg 338 Lapua.
I simply wanted to make a wild cat.
Maybe next barrel I'll cahnge it to a 30-338
