Sideways primers

Page 1 of 2Next

Having issues with my large pistol primers going in sideways on my XL 650 press.
I am loading 45 ACP rounds.
I am using Federal large pistol primers, and about 1 or 2 primers out of 10 rounds are side ways or deformed some this is way to many in my opinion.

I tried cleaning primer setup and also cleaning under the the shell plate.
This is a brand new press and the first time i ran 45,s things where fine now i change calibers back from a 40 S&W to the 45 ACP from small to large primers and it is doing this.no issues on the 40s but they where CCI small primers.
Ire read 650 manual and re adjusted the the machine as it said in the set up for cal conversion but still happening. I know it's something I am doing, and not the machine  just a minor tweak needed i am sure.
Thanks Mike

Congrats on the purchase. Check to make sure you changed the primer seat when you changed over the calibers. Be careful with the Federal primers! Are you trying to go too fast? Take your time and get a nice rate....learn to get that "feel" when the primers are seating.  Good luck!

 

Push down on the edge of the shellplate at station 4. If it feels springy, then the shellplate bolt needs to be tighter.

Push down on the edge of the shellplate at station 4. If it feels springy, then tighten the shellplate bolt a bit more.

Also note that .45 brass can be 2 different flavors of size primers. One uses large pistol, the other uses small pistol. Make sure you arent trying to jam a large primer into a small .45 brass primer pocket that got mixed in with your larger primer stuff.

Thank you all for the info, yes I did change the prime seat.
And also I did make sure they are all large primer brass casings,and I do appreciate these notes on the first 2 items never can be to cautious so thanks,
also I will try to slow and smooth out my stroke,
 Last night I loaded 85 rounds with 20 sideways or actually rolled over primers.
I have been double checking to make sure I put the primers in the pick up tube correctly, so that is not why they are upside down. I am leaning toward Dillon's suggestion to check the tightness of the shell plate,and also my smoothing out the stroke.
20 out of 85 rounds total bad, seems way to many to me.
Sad thing is I have 3000 Federal primers and as hard as they are to find right now  throwing them out is no option.
I guess I could also try some Winchester primers and see what they cycle like.I will let you know.
Thank you all Mike

I had a similar problem, including primers going in upside down.  My problem was caused by the shell plate being to tight.  I readjusted based on the DVD specs (same as in the manual) and backed off 1/8 of a turn.  I load 500 rounds at a time.  Now that I have the shell plate readjusted I do not have that problem anymore.  I hope this fixes your problem.

One suggestion: Use a "pause" in your push (down) stroke. Pause at the point where you reach the hands off position of the ram before you push the handle forward, this will allow the shell plate to properly index. If you push the ram down and then into the primer seat position in one motion you could be catching the primer pocket on one side before the shell casing indexes into it's proper place. I've modified my shell plate/bolt with the addition of a torrington bearing so I took more of the "slop" out of the movement. I did this to minimize the snap into position that was knocking powder out of the case (9mm). I've done about 8K rounds in my 650 and have only had 1 primer go in off center (it smashed half of the primer) I felt it immediately and not entirely sure of why but suspect I went too fast. I haven't used Remington primers but CCI, Winchester, and S&B all work fine.

I've had my press since 1998 and only recently experienced that very same problem using cci primers for 40 cal while teaching a friend the fine art of Dillon reloading. If you look at the different tapers on primers you will find they are different,I normally use all Winchester or fedral primers. You may also notice if your firearm shoots different as you shoot that cci primers are harder giving a delayed ignition to the powder.check the indention of the primer and firing pin depth if too shallow use different primers you will see a difference.I am a certified nra instructor and competitive shooter When you go to the range talk to other people you may find out a lot of stuff most people who belong to a range also reload.who knows you may find a new friend in the process.

Well last time i loaded was a month ago I did all the things suggested and it minimized the problem some .I have heard the Winchester primers where softer and that may have caused it but from what i am reading in the replies not true.After my out west trip I will pull out the re-loader and see what happens this time around.
I feel it must be in my stroke or the shell plate.
The very first time I ran 45.cals not one primer did this and it was the same type of primers, so i would say i have something just a hair out of set.
