A good dynamic load, won't matter much on the variances of .007". Which is what you are going to see with partitions. Yes sir, been sitting in your shoes before. The camparitor will lower that variances to .002". Which I think is darn good. If you want, I can loan you mine for a few days. See if you like it. I got the stoney point version. Its ok. If you take it apart and put it back together, the measurments can vary a tad. To beat this, I put it together with all my different pieces from .308, to .270, etc. And wrote down the length it should be everytime closed with it on my calibers.

Bottom line is with a stable load, it won't matter. But as a perfectionist like 90% of reloaders, it matters, cause you know.

I haven't forgot about your Private message. Been meaning to get back to you on my pet loads for 300RUM

I won't be home until this weekend, the teal are calling me in Dorchester county. But can meet ya on Saturday morning if you would like to play with it for a few days. Need it back before next weekend.
