I have a 257 Wby Mag and a 300 Wby Mag and have noticed some severe accuracy issues (2-3x MOA) I chalk up to copper fouling after sending about a dozen rounds downrange in the 257. The 300 is brand new, so I'm still learning how it responds. I know a lot of you out there have more experience shooting and reloading than I do. I'm wondering if anyone else has had this experience with the Weatherby cartridges and can offer some guidance or advice? I really like both rifles and should probably invest in some reloading equipment and a chronograph to get the most out of them.
Although I would prefer the shoot accubonds given the superior ballistics profile, I've found the 100gr barnes TTSX seems to work really well in the 257 with slower fouling. The barnes website states the lateral grooves on the side of the round minimize fouling because it gives displaced copper somewhere to go. Should I expect the same for the 300 Wby Mag? Does increased velocity equate to faster fouling? The cartridges for sale on the Weatherby website have higher listed muzzle velocities than any other manufacturer I've found, i.e. Nosler, Hendershots, etc.
Also does the manufacturer of the rifle itself make a difference? The 300 is a Weatherby Mark V while my 257 is a Remmington 700 CDL.
What methods work best for cleaning your fouled rifles and how often do you clean when shooting at the range?
THANKS!!!
