A Question for Jackie Schmidt - Case Necks

Sir,

Whilst preparing a batch of 6PPC cases for competition, I accidentally trimmed the case necks too far. They currently measure 1485 + / -. I understand for a overall chamber length of 1510, the recommended trim length is 1495.

I am currently shooting Bart's Boattails out of Krieger 13.5 tw /14 tw barrels, with a 045 leade.

I am shooting the boat tails at 7thou off the lands (7thou back down from where the bearing surface of the bullet just touches the lands).

Should I throw the cases out and start again?

What are the consequences in terms of accuracy of loading up short neck cases? and,

Given the short cases hold the boat tails securely should I be concerned or, is there a disadvantage shooting with short case necks?

I thank you for all your previous assistance.

I'm not Jackie but the simple answer is: Shoot Them. As long as they are all the same and you have good bullet grip....shorter doesn't matter (within reason).

It should be no problem, especially since the Barts BT sets up pretty short. (goes quite a bit of ways into the neck). As was said, just make sure they are all the same.

After 3-4 firings and full length sizing, they will be closer to your desired length..........jackie
