300 grain matchkings and 220 partitions. Of course this is not with the same powder, but its the best velocity i can get out of it.

I cant choose any of the large RUM's because of my bolt head. I don't want to pay even more to have a gunsmith change it to a rum bolt head.

The more and more i think about it i think 300 weatherby will be the winner. Although im still thinking about that 338 win mag.

338 rum, same bolt head as your 7mm, the gunsmith will however need to open up the rails in the action and install a ultra mag follower and magazine box. I changed my 338 win to a 300 rum (I already had a 338 rum)

If one's objective is to shoot bullets accurately and shot placement is paramount, then consider the cartridge that has the least recoil. Doesn't matter if a brake lessens it after the bullet leaves the muzzle; it still moves a lot while the bullet's going down the barrel.

Belted cases are not all that great for best accuracy when reloaded. Rimless bottleneck ones are much easier to reload to be a tack driver.

I consider the .300 RUM the ultimate compromise to have the best suite of accuracy, shootability and hunting performance at the longer ranges. It's worth opening up the bolt face.

If you take a look at Rich Sherman's (elkaholic) 30/375 S.I. i think you will change your mind.

I don't think so.

The difference in what they do with the same bullet's not worth having to reform cases before you can shoot them in my opinion. That subtracts from "shootability" which includes getting components and loading them.

I'd like to see the muzzle velocity difference between both cartridges with the same barrel length, peak pressure, bore and groove dimensions for heavy 30 caliber hunting bullets. This would be a realistic comparison. Even if the .30-.375 shot 'em 50 to 100 fps faster, that' enough to negatively effect "shootability." More muzzle velocity is countered by more recoil making the faster ones harder to shoot accurately.
