The 195 is impressive for sure. But the 30 cal 215 at .696 G1 is impressive also.
Or the 30 cal 230 @ .717 tops the 195 / 7. gun)
Anymore I consider barrel life as well.

Something we rarely think about in LR is BALANCE.
I have been as guilty of this as anyone. Back in the day it was a 264 WM that ate barrels and was twitchy to load for when there were many more balanced choices out there. Even a 30-06 with a 180 SMK would have been a better balanced rig but I had to have the fastest rig out there. Then it was the STW and then RUMs.
Now I am running an Edge, which while its a ton of horsepower is a very balanced rig and the 300 SMK or Berger is just serendipity.
Also I have kicked down from the RUM line to the SAUM line and guess what? 30gr less powder and giving up 100 FPS.
The 300 WM with the 215 is a superbly balanced rig. Enough horsepower, BC and not so much bearing area to make it twitchy.
A big 7 is all sorts of fun but the 7SAUM I am playing with now will do 99% of what any 7 will AND is EFFICIENT.
Balance and efficiency make truly great rigs. The biggest BC a lot of times is too hard to balance against the case needed and bearing area.
The 300 WM with the 215 is gonna be hard to beat, I think a smaller 7 with a 180 might be closer to a balanced rig like the 300 and like Broz said the extra frontal area is very nice in a game rig. A big 7 will NEVER beat a big 30 just as a big 30 will never touch a 338 on live animals.

I'm older than dirt and just now catching on to what toddc has stated.
I guess I'm kind of slow but sure am enjoying this stuff.

All of these have been hard to load for. Some I couldn't get bullets to hold together. All burned too much powder. WAYYYYYYY too much barrel. 30" tubes. Barrel torched right about the time I found a load.
Then I started working with the Edge and started thinking about EFFICIENCY and BALANCE.
Now I'm shooting a 6.5 Creed, 338 Edge and 7 SAUM. I even have a lowly 223 now!
Believe it or not the Edge is what got my mind on that. Yeah its a big honking rig but only runs 2850 FPS and is the deadliest caliber I have ever played with. Easier than anything to find a load for.
My barrels last longer than 3 or 4 used to lol. AND they are easier to tune and more accurate and i'm giving up 1 MOA of drop and .3 of wind at 1k. DUH.
Oh and I almost forgot, I would be more afraid to stand in front of the new stuff than the speed, BC demons I used to run. Getting stuff running near the ragged edge to perform CONSISTENTLY can be a real booger BEFORE the barrel is gone.

Todd,
My venture into that world was the 270 AM. 900 rounds toasted first barrel. 600 rounds toasted the second one.
That rig is now a 270 WSM. Other favored rigs are 300 Win Mag and 375 Allen Mag.
I think the 375 AM is the most efficient. Actually its the most pleasing to shoot and easiest to load for. It seems any bullet from the 350 SMK to the 395 Hammer Hunter are digested quite well.

Yeah maybe I made that word up but the more powder you burn behind a smaller hole + a long bearing surface = TWITCHY. 375 AM = BALANCE. Crazy big balance but balance.Todd,

The 215 Hybrid Target is the one that has been referred to. It's performance is well documented and well used.

I feel it will do all you ever wanted and more. It might even surprise you a little.
Keep us posted.

Does one really "need" 3000 with that bullet?
Gravity is constant, for identical velocity all trajectories are identical.
This leaves only consistent/quality reloaded cartridges then the big variable is wind and - the wind is your friend.gun)
My shooting buddy pushes 190s at 3200 in his DIY 300 Win on a Rem 40X action and has exceeding long case life.
