700's are notorious for a huge amount of freebore. A big jump isn't anything to be concerned about. Load your OAL to function in the rifle's magazine and move on to other things...

I shoot the same load with an A-max - 48.1 grains of Varget loaded to 3.240", CCI large rifle primer, Winchester brass. Not a smoking load at just under 2,600 fps from my 22" barrel, but it is very accurate and consistent out to 500 yards.
