How bout a 300-338 Lapua Magnum?
I have one and it's a lot of fun.
Reamer is on the shelf. no turn. Just squish the necks and you'll be reaping the benefits that $5.00 a round brings every time you yank that trigger!
Babies cry and mothers fall to their knees looking to the sky pleading "why God" when I drag this thing out. Especially when you set it up for 115 and 125 grain bullets. 4375fps on a 30" tube according to the chronograph at the COR-BON ammunition plant test tunnel.
I also have a 338 Lapua Magnum in AI if you want something bigger yet equally stupid!
