This is for both of you guys:
I've used RCBS dies for all of my reloading for rifles and pistols. The rifle calibers I have reloaded so far are 22 Hornet, 223 WSSM (traded it off), .243 Winchester, 7mm RUM, .308 Winchester, 30-06, 8mm Mauser, and 300 Weatherby. All are still reloaded using RCBS dies, and I have yet to see a damaged tip from the seater. I've loaded plastic tipped bullets, varmint bullets, HPBT target bullets, and hunting bullets. What brand dies did you have this experience with? Were they older or newer dies? Were you in any ways impatient to get the bullet seated? (Sorry, have to ask that one too.) Was any excessive force required to seat the bullets? Pushing down too hard or too fast can damage the bullet as well as the brass.
