RE: .338 Lapua?
I was wanting a Lapua very badly a couple of years ago. After figuring out how much the gun would cost and then how much the ammunition would cost I opted for the .338 Remington ultra mag. It offers very similar ballistics but at about half the overallcost. I have been very happy with it and have actually foundthat Remingtonfactory ammo (250 grainswift a-frame) will shoot under one MOA.
I have an HS Precision stock and a limb saver recoil pad installed on it and the recoil is surprising easy on the shoulder with out any muzzle brake. Muzzle brakes aren't worth it. IMHO if you think you may need a brake then I strongly suggest stepping down to a lighter recoiling cartridge.It is nothing to sid down and shoot a couple of boxes off the bench provided you are sitting correctly and the gun it at the correct level so that you don't have to lean over the gun.
Yes, I believe the cost, recoil, and everything associated with the gun is worth it. I love it.
