Shot a Creedmor match a while back. 800, 900, & 1000.
Figured I need as much velocity as possible, plus I used hard bullets and heavy crimp.
Yeap, my bullets whissled through the air, sounded like a buzz saw.
I was shooting with some national champion BPCR shooters who got me lined up.
At their request I switched to soft pure lead, got my velocity between 1100 and 1200 and stop crimping the bullets. These guys seat the bullets by had just before they are loaded in the gun.
It made a huge difference. Like a whole new rifle.
