Why I Crimp

[tribb]

I discovered that many years ago. Particularly true for 223/5.56. My solution to that happening was to just take .005" or so off the bottom of the sliding collet. Works like a charm! That way, I can always trim to minimum length and still get a solid crimp on every case.

The sliding collet on what? Tribb

It was a couple of years ago that ButterBean and I discussed whether to crimp or not. I was working up loads for the Tikka 270 at the time and without any crimp was able to get 0.070 to 0.075 groups. Got a Lee Crimp Die and gave it a try with just a light factory style crimp. Group size dropped down to 0.55 to 0.60. Have been lightly crimping everything since, 223, 270, 30 and now 338 with fantastic results.

Teri Anne, I'm pretty sure I follow your drift, but it looks like the zeros slipped on the 0.070 to 0.075?
It makes more sense if that was really 0.70 to 0.75 such that it improved with 0.55 to 0.60.

Thanks Bean I'm gonna try it for sure. On bullets with grooves like hammers do you want to have the crimp in the groove or on other part of bullet that's between the grooves.lm thinking on the hump between the grooves. Am I correct? Tribb

You are correct

They can be "Tuned" if needed, I'm set up to do that if need be

I'm just glad you had an open mind and tried it, so many on here are not
