    What is going on at JP Enterprizes?

    Re: What is going on at JP Enterprizes? This is starting to smell like a drive-by bashing. OP, get on here and defend your credibility. If you can't, delete your post....small companies don't need undeserved bashing.

    Crimping Ar Loads

    Re: Crimping Ar Loads I crimp everything, but it is not absolute protection against the incident the OP described. If a bullet is set too long and you slam a round home, the bullet will still likely get shoved back in the case....crimped or not. That's been my experience anyway. FWIW. But...

    What is going on at JP Enterprizes?

    Re: What is going on at JP Enterprizes? Bought a lot of triggers from those guys over the years and never any problems except of my own doing....I screwed up an install once and they had a part out to me the same day I called for help.

    Range Report Help with manually calculating DA

    Re: Help with manually calculating DA Jo, Just to warn you, calculating DA is no simple task. It's also beyond one post, so I am going to refer you to the below links which should get you going. The NOAA paper is probably better. As you get in to it, you'll see that you can make your...
