Post subject:  Roll Crimp Questions

I purchased a new roll crimp, the ExactaRoll Double-Pin Roll Crimper 12ga. from BP. This is my first Roll Crimper and I am wondering how it looks and if worked right.

It's not rounded, I think because of the double pin style of crimp? Not sure... I have never roll crimped before this was my first attempt ... opinions?

Thank you.

Send it back the roll pins have not been profiled to leave a round edge.

Ya they are not supposed too, this one does a flat type of a surface?

I have it in mind that the BP roll crimping tool is supposed to be used with drill head turning counter-clockwise. Might try changing direction of you swirl tool.

nope directions say clockwise... I called and bp says it looks good?

Only other idea is to make sure you are applying the swirl tool slowly; giving the plastic time to warm up and form a better "roll". That said, roll crimpers are a tool from the dark ages of paper hulls. Have heard some are better than others with plastic, but paper is standard on which these tools originated.

They did mention to heat it up a bit more maybe... Other then that they said it looks pretty good and will get better with time as the crimp gets use.

thank you.

I went with a couple of BP roll crimpers until I ordered a Prescision Reloading crimper and I'll tell you what... there is absolutely no comparing them. I just roll crimped about a dozen turkey loads and 50 - 410 loads with all once fired hulls and they look perfect. They all have that nice rounded edge and look like roll crimps did when I was a kid.

I also found that when reloading 12 ga steel loads with the BP crimper, it sured seemed like I was getting some increased pressure. With the PR crimper, the loads are very consistant. I did not send my BP crimpers back, but I do not use them any more. I chauked it up to a learning experience.

I can apply a roll crimp from 10rpm to 2000 rpm and it will roll the edge of the case over within 5 seconds fast or slow and leave a tidy internal edge from stone cold , The roll pins have a crescent shape to them as from new. Yours is entering the roll crimp tool and hitting the pins which have not been rounded off,
They should ROLL the edge inwards instead of hitting a flat pin and being forced to go inwards from a dead end and leaving and untidy internal edge and flat top.

Exactly! The crimp shouldn't be flat. It should be rolled inward. The PR cimpers have the raised crecent shaped indents (4), also. They are almost a clone of the old Lyman crimpers. All I know is they really do a fine job, but there are some other brands that do excellent as well.

The crimper shouldn't have to break in or be a certain temp. It should generate the heat needed to make the roll in just seconds.

They should be more like below, they are made on used target shells with a crimper from www.gaep.net

Thanks everyone for the tips... I am going to give it another try before sending this one back... I think I may be applying too much pressure. This is not the normal roll crimp ??? I think..? ... it was a design for some Military app.

Here is what the website says:

"New for 2010 ExactaRollâ„¢ double-pin roll crimper (12ga only) This is our premier roll crimper design. We've doubled the resistance rollers to make this our most efficient roll crimper ever. The double-pin design of this crimper offers the handloader greater crimp control, tighter sealing and roll crimps in half the time. We designed this for a military client and we liked it so much that we had to offer it to you too. Oriented for clockwise rotation in either drill presses or hand drills."

I don't know maybe its supposed to be square? Do all roll Crimpers have the pin?

Not from GAEP, they are machined like a curve instead of the pin design and at the same time rounded, sorry mine are a little rusty because I used sulphone as lubricant, today I use WD-40 as lubricant when I crimp

So in affect yours has 3 "pins" from the looks of it, but smaller... mine has the 2 but very pronounced. I think I may have been applying toooooo much pressure.

Post subject:  Re: Roll Crimp Questions

It's not like 3 pins but curved between the 3 points

Post subject:  Re: Roll Crimp Questions

Very similar to the PR crimper. They use four raised points, but pretty much the same. I also us a Hull Reconditioner that "irons" out the old crimp with pretty good sucess as well. On the 410 I do not. i just mad an iron out or a bolt that helps relax the old folds. Nice crimp with that Gaep tool!

Has anyone here on SGW ordered a set of the roll crimp tools from GAEP?

What did it cost at the end of the day, and how much of a hassle was it to do the whole overseas thing?

Are these also used in a drill press?

Does their set come with hull vises, or do those need to be bought somewhere else?
