Tight fitting primers-

About a year ago my shooting buddy drove up to Prescott and during the trip stopped into a nice local gun shop. I was needing primers and buy Federal 210 LRs, which they were out of. However, they did have one box of Winchester LR primers so I bought them. They were old judging by the box as the box they came in looked like they could have been made 20 years ago (box of 100).

Anyway, back to the loading bench I was using these and priming some once fired Hornady brass in 6.5mm CM. The first few, and a few others throughout the session, went into the primer pockets in a fashion that I would characterize as normal. All my primer pockets were cleaned with wire brush and the brass cleaned via ultrasonic.

Then some of the primers took an extraordinary amount of force on the press (my buddy's RCBS Rock Chucker) I was using to get them seated, but seated they were and not proud. Now here is the reason I am posting. Probably a fourth to a third of the primers extruded a small sliver or thin strand of shiney metal that appeared to be coming off of the sides of the primers, during the seating process. Kind of akin to the fine strands of metal that come off a piece of metal from being worked on a lathe. I have never had this happen before or since, nor have I read anywhere about it happening.

Anyway, I finished priming and went ahead and charged the cases and seated the bullets but did not have occasion to shoot any of these last year. The charge weights are all a couple grains under max per the book.

So, my question is are these going to be dangerous if I shoot them? I've got a press style bullet puller and can disassemble these rounds if the majority opinion here thinks that is best.

I was new to reloading and still am, so I figure if I use these at all it would be for cold-bore and foulers. As I said, they are loaded light and I've since got much better loaded cartridges to shoot on hand. Thoughts/advice/counseling are appreciated. lg
 
You should be fine with them.....I had to read again to check what brass you're using as primers are sometimes crimped in but that's normally military brass. This crimp unless removed can make primers nigh on impossible to insert (don't ask me how I know) unless you remove it with a primer pocket uniformer or a quick turn with a neck chamfer tool.
Just watch for crimped primer pockets and the telltale ring pressed into the circumference around the pocket.
Otherwise, I've never come across Hornady brass with a crimped primer and we use it a few rifles.
Anyways, take a cleaning rod to the range just in case you get squib fires and need to push a projectile out of the bore.
 
Thank you Homerange. Hoping to get out Thursday or Friday if it quits raining (in Phoenix area). Want to check zero on my rifle and then shoot some of these rounds I have loaded with the tight fitting Winchester LR primers. Roger on Hornady Brass. I buy boxed Hornady ammunition and then use that brass to reload with. No crimped primers. Thank you again. I will post results as soon as I have any.

Oh: and will take a rod with me and be leary of squibs. Mucho appreciate that tip, because I had not thought of that. I can see my hits on paper at 100 yards thru my scope, so if I don't see a hit, I'll know where that bullet is. :)
 
S&B primers would do the same in Lapua 6.5x55 cases. I had to periodically take an air gun to my hand primer to blow out the metal shavings. Those primers performed very well however. I figured I would return to them for brass lots that started to get loose primer pockets.

THank you. Good to know this is not something new. Glad I posted the situation. lg
 
Dimensions posted, but don’t forget there’s a range of manufacturing tolerances involved here, so the listing isn’t carved in stone. You might also want to make sure the cases are fully seated in the shell holder, and the primer ram in perfect alignment with the waiting pocket. Even slight degrees of misalignment can make the primers feel unusually tight during seating.
 
Correction, .0006" larger, not .006". 6 ten thousandths isn't much and the reality is that I doubt that any primer is manufactured to tolerances of much more than plus or minus .0005".
 
Appreciate your guys' comments! Just FYI, this was a one time thing for me. I load using Federal 210 LR primers but at that particular moment could not get any so bought the Win LRs (actually, half the reason I bought them was to give the gun shop a little business as it seemed a slow day for them). I've loaded the 100 Win primers (last year) and am going shooting tomorrow, so wanted to check here to see if anyone had any reservations about how safe they would be to fire.

I spend winters in Phoenix and summers up N on the high plains. So, loaded the Win primers late last winter, did not have a chance to shoot any of them until this year (tomorrow hopefully); to explain the time line. I've got 1000s of Federal 210s on hand now. :)

THank you again everyone. Great forums here! lg
