Fitment issue with Lapua brass and Federal Match primers

[Badfinger]

I'm loading for a .260 Rem using Lapua brass and Federal 210M Primers and they're very tight and some won't even seat with a LOT of pressure. Anyone else seeing this issue?

I had 0 issues with BR2 in Lapua. They were snug but always seated properly.

What priming tool are you using? Are they getting pushed in crooked?

I also found that to be the case. What I do now is use salvaged primers which are slightly smaller and seat in there easier for the first firing. 210s seat ok after that.

5# mallet? Dead blow hammer? -grin-

I find my hand priming tools don't work as well as my 650XL for seating those bastards.

I'm using the primer system on a Rock Chucker press and they appear to be seated and straight going in. I've been loading for over forty years and haven't seen it this bad. I was jamming about 30% so I used my primer pocket swaging tool.

I am using an older hand held RCBS priming tool. Yes every now and then i get one upset by 90 degrees. Takes a lot of attempts to get it smashed flat enough to get the case out of the shell holder. But then i deprime it and seat a new one without issues

Mine are going straight in but won't seat unless I swage to hole. I don't know if it's the primer or the brass or some kind of tolerance stackup between them.

Even if you are not using once fired brass that needs to be swaged, you won't go wrong puttin a slight chamfer on the primer pockets

Quit limp wristing. You won't have that problem. Just kidding. maybe
