7mm/338 Lapua Imp. build?

[steeltraps]

Got the itch to build a 7mm/338 Lapua IMP. I have the reamer, barrel, and dies so their no talking me out of it! But I am woundering how fast I can push a 180 berger? Can I get 3600 fps with a 180 Berger and 30 inch barrel? Does anyone have experience with this round? What will barrel life be like? Im hoping for atleast 800-900 rds? Any info on how fast you can push a 7mm will be apprecited. Thanks in advance!

A 7mm Allen magnum is a improved 7-338 Lapua Imp. It looks like 3400fps is much more realistic with 180's.
