Home Forums Reloading Big Game Rifles Rifles that just won't shoot?

Copper fouling proved to be the biggest problem with my 300 Weatherby. I cleaned the rifle regularly but only with Hoppes #9. It could not consistently shoot better than 2" groups and often much worse.

With a 1/12 twist and a pencil barrel it is not meant for pounding away at the range with spitzer boat tails. I chased many leads but in the end, it was the copper. After extensive cleaning I can consistently put together 1 moa groups with the right load. That is as good as the factory advertised back in 62 when the rifle was made.

In the process of chasing many leads to improve the accuracy I must say I learned a lot and am the better for it. I will continue to try different loads to see if the rifle can do better, but with its light weight barrel, long freebore and fast twist it was not meant to be a 600 yd varminter. Hit big animals real hard is what it does. I use it accordingly.
