Interesting comparison Login/Join

I just realized how closely the 7 mm IHMSA International and the 6.5 Creedmoor resemble each other. I know -- slow on the uptake.

Anyway, a 7 mm IHMSA International has recently come my way, along with a bunch of unfired and fired brass, and in looking at it I wondered to myself "how much different is this from 6.5 Creedmoor?" I mean, I know the bullet diameter are different by half a millimeter (duh), but putting the cases side-by-side, there is so little difference it's amazing.

The 7 mm IHMSA International looks like a very fine cartridge, both for silhouette (which it was originally designed for) and for small and medium game. Looking at this photo, I would estimate it would be good for anything up to antelope and deer inside 150 yards.

When I can get myself organized (ask my wife how soon that will happen!) this one will be looking for a new home, along with 197 pieces of brass and dies.

Here's the photo:

Is the 7 mm IHMSA International based on the 250-3000 case? I've forgotten. Definitely a difference in shoulder angle and it looks like the 7 mm IHMSA International is a little shorter.

The 7mm IHMSA is based on a 300 Savage, I had one in a Wichita bolt gun and it was very accurate and with 120 grain Ballistic Tips it was deadly on deer sized game. I sold the gun to a buddy who's still killing deer with it.

As the later poster said, it is based off the 300 Savage. It is just a little shorter than the Creedmoor. The shoulder is not as sharp, and it could be blown out a little more. My recollection is that when Elgin Gates first developed the cartridge, there were two designs. One was a little longer than the other. I think this one is the longer one. I have not tried this with the 120 gr bullets -- it might shoot better than the 139 gr bullets , which is what I have.
