RE: 7mm Mag Or 7mm08 Or 7mm WSM ?
 

True but it doesnt offer anything the 7mm-08 doesnt already have. All of these rounds are great choices, just in my mind when you go custom you go big.

To be honest I was only looking at the 3 he mentioned.

7mm Mag is a great cartridge but long. The short mags are more consistent - or less varibale due to the shorter case - I have a 300 WSM that is accurate like a 308 but I do not see the 7mm shorts much.

7mm saum.

RE: 7mm Mag Or 7mm08 Or 7mm WSM ?
 

Well, I am now partial to the 7mm WSM since I got one fer christmas. It really doesnt do much more that the ole 7mm rem mag does but it does have a few advantages. The sammi pressure for the rem mag is 61000 and the rating for the WSM is 65000. So it seems to give a little more leeway to the handloader. But do what you want. Just thought Id say my peace. EJ

I'd go with a 7mm-08, a 7mm Rem Mag and a .280 Rem.:)

If you handload, then toss in a 7x57.

If you have a 7mm Rem. Mag. in, say a Model 700 Remington and a 7mm WSM in the same type of action, they can both be loaded to the SAME pressure levels. And when the 7mm Rem. is loaded to the same levels as a 7mm WSM, it will out-perform the WSM because it holds MORE powder....... of course, this is assuming you select the correct powder. With IMR 7828, I get 3050 FPS with 175-grain bullets in my 26" barrel 7mm Rem Mag. Ruger No. 1.

Of course, I have no idea what the pressues are, but I get ten reloads out of a batch of cases with this load without primer pocket expansion, so I don't really CARE what the pressures are!

RE: 7mm Mag Or 7mm08 Or 7mm WSM ?
 

7mm rem mag b/c it is the overall best performer of the ones you listed for the .284 class bullets.

Since your building one for school it might be nice to build something other then you can buy off the shelf, little different but still has appeal. What about a .280rem AI. Not something you see everyday will offer performance gains over the 280 rem standard version(very close to the performance of the 7mm rem mag) and no factory chamberings of this kind-unique. You can shoot standard 280 rem cartridges, not getting the boost but appealing if selling to other than a handloader down the road, with the option to AI case use for the handloader.

Or like mentioned if you really want to step up the performance the 7mm STW would be something to consider as well.

Good luck

Ever think about the EXCELLENT .280?
I'm a 7mm slut so you can't go wrong with any of em.
