Are the SAAMI pressure levels for the 300 Weatherby lower than the Norma factory loads? Some of the reloading data like Speer and Alliant look like they are as they give very little advantage to the Weatherby. My experience a 26 inch barreled Winchester comes darn close to a 24" Weatherby. I was going to re-chamber my 300WM but decided not worth the expense and it shoots lights out now so not worth the risk.
"When you disarm the people, you commence to offend them and show that you distrust them either through cowardice or lack of confidence, and both of these opinions generate hatred." Niccolo Machiavelli
