I have read that the Lee Crimp Die inproves accuracy because it produces uniform tension of the case mouth on the bullet. I purchased two crimp dies, one in 300 Win Mag and the other in 375 H&H. The 300 Win Mag shoots under an inch consistently. The 375 H&H has not settled down to any better than 3" at 100 yards with 220 gr. bullets. With 270 gr. bullets, the 375 H&H is more like 5 inches at 100 yards. Same with 300 gr. bullets.

I know that I still have a lot of work to do on the 375 trying to work out the best loads.
Just interested in other opinions about the crimp die.

Thanks in advance,
