24g of 4320 with a 25g Berger, Rem 7 1/2 was my accuracy load for a long, long time, hunting partners also. Then we switched to Win 760 with a zero freebore reamer.

Later on, we switched to 22.0g of H322 for a velocity of 3850, shot strings got longer without copper fouling out the barrel, and the carbon amount was sure less.

Here are pics with a little over 1000 rounds of varget with 20g fired, Lilja barrel

I call BS.

I have seen nor heard nothing of Varget being worse than any other powder at eroding throats. I imagine the way one shoots and how long the shot strings are would be far more relevant than which powder one chooses. I use Moly'd bullets, a moderate load (according to Hodgdon) and get 3997 velocity average out of a 24" Remington barrel. The gun is over 30 years old, and has been shot hundreds of times. There is zero roughness by feel in the throat.

I belong on eroding granite, among the pines.
