well today I loaded up some 125gr .357 XTPs. Being that thy are larger then the 9mm versions I was a bit concerned about the pressure. I loaded them to an OAL of 1.27 with 10gr of Longshot. i tested 15 of them as thats all i loaded. i did not have my chrono so i don't know the speed but thy shoot just fine and the primers looked just like if i used .355 sized bullets. so now i will load from probably 10gr to 11gr in .2 steps and test for velocity.
