Hey guys I've got a Remington 700 in 7mm rem mag that I bought off of gunbroker hoping to turn it into a long range rifle. I'm not really looking to turn this into a wildcat caliber, just wanting to stick with 7mm. Anybody got any ideas as far as finding a good drop in barrel, length/twist. Also would like to change the stock and trigger as well. I've already got a leupold mark4 with custom reticle so that's not a problem. Also anyone one with any built up loads reaching 3000fps would also be appreciated! Thanks Guys!
