What did he order? What press? What brand dies? Which loading manual does he use? What brand and weight bullets?
Make sure he doesn't exceed the pressure limits for the gun. Start with lower charges and work his way up and record
accuracy results. The max loads are usually NOT the most accurate, keep that in mind, not to mention they will burn
out the barrel (actually the lands will go first). Be safe and careful. Check tolerances often, especially charge weights
and seating depths if long range accuracy is a serious concern.
Interesting note is that the 6.5 Creedmoor uses a 6.7 mm. (,264) dia. bullet and the case length (short throw action)
is similar to the .243. As stated, the 6.5 is a good "mid sized" rifle cartridge. The .45? It has been time proven. Nuff said.
