Home Forums Hunting & Shooting AR and Tactical Rifles Handloading for an AR

I’ve loaded 1000s for ARs, never crimped a one. And they work perfectly.

I just put forty rounds of 62 gr Fusions thru two 20 round PMAGs, no crimp, and no problem. Fired slow for groups, and three to four round bursts for checking function. Looks like no-crimp here. Thanks to all.

If adding crimp reduces your indicated runout, you probably have something funky going on elsewhere in the loading process. Obviously we all like straight ammo for accuracy, but crimping isn't usually necessary or helpful.

You are a fu cking idiot. That is an old trick to reduce run-out. It's also the way I set all of my dies and I get far better accuracy than most do here. How do you fare at shooting and accuracy? Until you can start proving you know what you are talking about, I'd suggest you shut the fu ck up.

Yowser this escalated fast..

Wow! Evidently a couple of you guys don’t like each other!

BSA can be a little grumpy from time to time.

I suspect he just needs some range time to decompress.

Most of us could probably use some more range time.

I can't say I understand how crimping would reduce runout, nor do I recall having heard of it being a trick to do so. Maybe my memory is going.

I can see how if everything is just right it wouldn't harm runout.

One more thing to test ...

Never had any problem with him before, but apparently do now, I guess?

Calm down Francis. That sure seems like a lot of anger to put into something so minor as crimping; maybe it's really about your need to prove that you're the best person here all the time?

If you can set that aside for a minute, could you explain how/why adding crimp straightens out a crooked round? Show us your runout numbers and explain what the mechanism is that straightens out the rounds when you crimp.

I could picture maybe if you've got a sticky expander ball pulling necks out of alignment, that adding a crimp might push the neck back down into place. Not sure what other mechanism could be responsible for the straightening.

Never experienced that phenomenon myself, but maybe that's because I can't shoot, like most everyone else here.

I see the village idiot is at it again.

Want to see him get really twisted? Ask him to prove up on all the elk he claims to kill.

Crickets.

Just checking back.

I'd like to know what's up too, but guessing he realized his tantrum was unfounded and isn't willing to explain or apologize. Too bad.

I think it can be attributed to ass holes colliding.

Lastround,

This is your answer.

Thanks to all.

That's pretty damned funny.

Lol

Checking in again.
