Have an issue with 124 gr lead cast bullets keyholing in three different guns one Smith two Xd's loading bullseye 4.5 grains per Alliant specs right around max loads.My thoughts are its to hot of a load to stabilize the bullet.I was curious if anyone else on here has had a similar problem.I may need to switch powders to something a little slower.Factory loads shoot ok just the cast is the problem.cast bullets weigh out very close 124.8 to 125.1 just looking for some ideas before I start switching things around.
