I have a rpa .22-250, so the barrel is good. I have a rough idea of my velocity (last year I chronographed it), it is around 3900fps with a 50 grn bullet. Although I have altered the load slightly and need to chrono again asap.
With that load im getting quarter MOA. I dont want to do any damage to the rifle. Has anybody experienced throat erosion or damage with a similar load/velocities? Am I worried about nothing?
