Thread: 180gr eld m and 7mm saum

In that factory twist and barrels the 180 often shoots .6-.7 groups, which some hunters accept and others don’t

The 180 is not the best harvester of deer at the reduced velocities a short tube gives, a 150 Nosler BT performs far better in short tubes as it’s velocity far exceeds the 180 grainers

A 150g fits in the mag too without alterations, and loves ADI 2217 which is the least temp sensitive.

There’s a reason the 150/162 has been used effectively since 2002

Save the 180 for the longer tubes or the rem mags

I agree, I run 162gr Amax/eldm in my 22" 7Saum @3,050 fps, I rarely shoot deer inside 500 yards, commonly shoot them out between 600-700 yds and generally don't wish for anything heavier, the 162 seems to be a nice balance of velocity and weight and bc, and that bullet seems to put the hurt on them pretty hard. Longest deer shot with this combo is 994 yds, it poleaxed it but the shot was high shoulder and put a fair amount of shock into spine. In my opinion the 162gr at 3050 fps is getting a tad marginal at 1000 yards.

If you don't plan on shooting further than 750-800 yds then the 162/168 is plenty enough.

Thanks for that guys
