Re: armalite ar-30
As long as your in decent shape you should be fine with a bit of hiking. And if your hunting, pick a nice spot in a high place and bring a lunch. No stalking with this thing. Obviously it can be done, but trying to image crawling through some fence wires with the length of it would be a pain. Just get a nice padded sling for it. Imo, the trigger was pretty nice being on the stiff side. It's been a few years but I want to say it felt around 4.5-5lbs pull. Barely any slop on mine. If I was stuck with the AR-30 again, I would replace the pistol grip to an Ergo soft one instead of the hard plastic one it comes with. And I would replace the trigger. A bipod is an absolute must. Hope this helps.
On a side note. The reason I bought it was to get into the .338LM cartridge. If I was looking at a 300wm I would look into a Rem 700 Sendero and have a smith put a brake on it. You will get more accuracy out of a Sendero and have plenty of upgrades available. The AR-30 can be had for around $1650 and a Sendero with brake installed would run you around $1200. The AR-30 is long and really bulky, kind of overkill for the 300wm and the 308 versions it comes in. But if your set on the looks, go for it. It really does turn some heads as it looks just like it's big brother (.50). The muzzle brake is amazingly effective. Good luck!
