I run 140 AB's up to 2900 out of the M70 Featherweight with RL17. Cases seem better than running a less pressured load of RL19 with a 140 BT at 2700.. I run my loads up to around 60-62K PSI via QL, and try to stick with it.

Haven't seen any negatives and when run up to 60K, the 7mm Mauser is very awesome.. It has made me a believer.
