I just bought an awesome CZ 375 H&H, all my reloading stuff, powder, Barnes 300gr TSXFB bullets, cases etc...
I got everything working and started seating bullets. COL worked out to 3.555. I seated 3 bullets, measured them and they were all 3.554-3.556. Good to go!
Large lock nut on die was tight and hex screw was tight. Set nut on top of seater was tight. Pushed 10 bullets and got a range of different sizes...from 3.60 to 3.446.
I measured the bullets - all were withing .001 of being the same length. I measured the cases (Remington) and they were all the proper length. I find this difficult to explain, thus the question? It seems to me....if the cases were longer, the bullets were longer....it shouldn't make any difference because when you lock everything down you have a particular length dialed in regardless of the length of any of the components. Right??!!?? I use the same stroke and pressure when I seat the bullets. I inspected my press and all is tight and operating normally.
Can anyone tell me where my mistake is or how to fix this problem or both? If you need more info let me know and I will fill you in.
My wife is complaining about the bald spot I am creating scratching my head on this :P
