Re: LRKM update?
I'm pushing a 300g Berger 'Elite Hunter', .015 off the lands, with 100g of Retumbo at 2954fps MV out of a 29" Rock barrel with Kirby's 338AX, his version of the 338 Lapua Improved.
It'll be very interesting to see what kind of accuracy MV and barrel life Shawn gets from this new +P 338 Lapua Improved chambering. If the MV improvement for the 338 Edge is any indicator, we could be seeing numbers in the 3200 fps or more range. Yikes, what a hammer...
The things about this project that I'm most interested in is, 1) can he get good MV and accuracy out of a 10lb. (unscoped) rifle in this new chambering in the LKRM and, 2) what would the OAL of such a rifle be and 3), is there any way to make this design have a magazine that will hold a couple of rounds?
I think Shawn's LKRMs so far have been running in the 15lb range scoped, if I recall--too heavy for me to want to backpack, although I do like the fact that they are substantially shorter overall (sounds like better balance because of this) than a standard LR rifle of similar performance.
I also like a rifle to have an extra shot or two, mostly for use for sneaking in the trees, but I have had one occasion on a LR elk that didn't immediately go down, with the first hit from a 240g SMK, and I was thankful for a very quick second shot from the magazine that did put it down.
