Re: Scope thoughts for an AR10
For some reason I thought you were in Western Canada. No matter, it still sounds very cool up there. The months at a time isolation we could definitely handle without problem, maybe even the low temps. But besides the low temps in January, don't you also have weeks or month of night followed by uber long days too? My wife couldn't handle those perpetual nights, would drive her nuts. She's like a plant in that she needs sunlight.
I've been buying firearms on Gunbroker since 2001. Never had a problem, but then I'm careful to the point of being paranoid. Only buy from sellers with lots of good feedback. Once the transaction is done, they ship to my local FFL, and I then go pick it up from them and pay the $5-$25 transfer fee. Almost like buying a gun from the dealer only the didn't sell it to me. Works darned well and allows me with a bit of careful shopping to buy at or below dealer cost.
As for that .338 Lapua you're considering, you should also consider a 50BMG. I've shot both, and have a 50 Barrett M82 (semi-auto) myself. The .338 was from a bolt action. Kicks like a mule, BAD (what I call a hurtstashootit) but was still fun and a good flat shooter. Super sweet precision rifle too.
Shooting the .50 is shooting a personal sized cannon shell from a personal sized cannon in on the target. Much more "industrial" feel to it, but undeniably effective at 1000+ yards. Recoil is like a 12 gauge.
Used to be that 50BMG ammo was way cheaper than the 338, but not so much anymore. Last I checked the two were getting pretty comparable. Course you can shoot mil surplus stuff out of the 50 for less, especially if you buy in bulk, but won't be really accurate versus the 338LM. Also tends to be a bit cheaper to get components for the 50 if you reload.
Rifles wise, again you're looking at comparable depending on what you want. Figure $2000 ish to start up to $8000 plus. Maybe less for you with AK List. Sure wish I had something like that down here.
Anyhow, back to work for me. And scope shopping. Wish someone could chime in about the Trijicon AccuPoints, but maybe in time.
