So what does .28 Nosler do that 7mm Rem Mag doesn't besides sell a bunch of reloading gear so that you can feed the rifle?

Throws the same bullet 10% faster. Not that that matters to some people, but for some it does.So what does .28 Nosler do that 7mm Rem Mag doesn't
Off the line a bit BUT. Just "making a shooting table" doesn't account for the biggest IF in long range shooting-- W I N D. The magnum's velocity gains more than just reduced bullet drop, it also cuts the wind drift.
I just went to the Hornady site.
Based on their 7mm 162gr SST with a G1 of .550
I ran wind drift at 2900 fps at 1000 yds as 74.6 in
I ran wind drift at 3100 fps at 1000 yds as 67.4 in
wind 10 mph 90 deg.
So ,yes. 2900 fps gives approx. 10% less windage at 1000 yds I agree.
Who can estimate wind to less than 10% at 1000 yds?
We are talking 7 inches total. Hunting conditions. Assuming you have the ranging and ballistic tools and experience to take a game shot at 1000 yds (I do not) how much does that 7 in make? Its 3/4 MOA. Assume 3 clicks.
You still make the same calculation .You still count clicks
You do pay considerably for that 200 fps
First, your not gonna get 2900 fps from a 7mm08 with a 24" barrel, I know that as I shoot a 7mm08 with max loads a 160 AccuBond will get around 2780 in my 25" Shilen barreled 700.
That same bullet leaves my 26" Model 70 (7mmRM) at 3200 feet per second.
That is more than 200 feet if my math is right
