Pure lead is about 2,100 fps when it will start to deform in flight. the XTP is a jacketed bullet. you won't even get close to that. i suggest 3- 5 shot groups start at say 85 and keep working up in 5 gr increments until accuracy falls off and stick with that load. your rifles sweet spot may be 85 or 105, you won't know until you experiment with the different loads.the XTP is a good bullet, any problems with them would probably be at close range with high velocity loads. i see your in nevada where long shots are possible lol. i am in cali myself. a lot of people on this forum use goex. so they may chime in about it. have fun.Ray
