I ran nothing but 71/2’s for years and years. Mine only made one pile, empty/fired. I just opened a “brick” yesterday it was dated 02-03, $43. They were scarce and hard to come by even before today.
I have since used 450’s off and on. Just yesterday I ordered 5K of 450’s shipped and tax came to $111.60 per 1k, yeah it hurt but that is split three ways with buddies.
I never weighed any primers, when I do start weighing primers I will personally sign a post card and send to every member here from what ever country I am in where I won a championship…….

I am having an occasional Rem 7 1/2 blow out in the radius. Never at the firing pin strike. 223 across the course loads in an AR. CLE chamber, RL-15, Sierra 80 MK's & 300 ydload, H75. LC brass. Kept backing off powder, didn't seem to help. Previous carton worked fine. Remembered I had recently opened a new carton, different lot #.Digging on the internet, I found info ref this problem. Seems Rem went to a two legged anvil in this primer, which seemed to be the culprit. Not sure how long before they went back to the three legged anvils. Lot# 330 is my problem lot #. Am using them up in my practice upper with mild 55fmj offhand ammo. Still blows one about every 25-30 rounds.
Any one else hand this problem? Probably purchased at least 10 years back.

I had over 4k of these from my XTC days and never opened them. When I ran low on SRP a couple of years ago I broke them out for use/testing. I got the same blowouts that you describe. I found out that Remington made 2 leg anvils back in those days that were known to blow out. Check your primers and if they are 2 leg you can try to get them replaced with the newer 3 leg versions direct from Remington. I took pictures and sent them with a note explaining the problem. They sent me replacement new primers in about 2 weeks. Excellent service, especially since they had just gone bankrupt and changed owners........

I had heard about primer cup leaks in certain Winchester primers and also about this batch of REM 7 1/2 and luckily I had neither batch.
I have said it before many times, and I will say it again here as a reminder, that every single brand has had escapes ranging from the annoyance of poor performance, to serious reliability issues. If you live long enough there is a likelihood that you will see it again.

@Sumtoc can you put up a picture please? i think my primers are three leg. I havent tried these 7 1/2's yet I bought them as we were heading into lockdown in 2019 and I think Rem was going out of primer manufacture, I picked them up for $55 NZD when 450's were running at $99 NZD so I hope I got a bargain not a nightmare?!
Sorry, out of town until Tuesday. Will post a pic when I get back. But the difference between 2 leg and 3 leg anvils is pretty clear.....
kiwijohn, easy to see the difference between a 2 legged anvil and a 3 legged anvil! Compare them to any other an you'll see the difference if two legged. Whats the lot number on yours? 330 was my bad lot. [

I remember seeing a test write up a few years ago comparing flame intensity of small rifle primers. The 7-1/2 was the hottest of all tested. Thinking tha might be good medicine for my 30BR, I tried them. So far, they seem to work better than others I’ve tried -205M, 450, wolf (35-ish h4198 in 23” bbl). Used 7-1/2 in gas guns for years without issue, as well. One thing for sure, is they take up a lot less room on the shelf because of the way they are packaged.
I have two bricks of Rem 7 1/2 primers from the late '60's early '70's that are 2 leg anvil style. My late '80's, '90's, and 2000's bricks are 3 leg anvil. Also have two bricks of Rem 9 1/2's from the '60's that are 2 anvil. I've shot multiple bricks of these old Rem 2 anvil primers that I bought at estate sales over the years and never had a problem.
Hi Frank, I am pretty sure mine are 3 legged, I dont think I have ever noticed a two legger, I am guessing they would have only two metal fold downs that go under the primer compound.
Yup, this is a great picture to compare.

Well the CCI 450’s were $40 per thousand cheaper than the Remington 7 1/2’s so I bought several 450’s.
I agree with most of the replies… Buy them if you get a chance…
All I've ever used for 223 and 6.8 SPC. They work great. Buy all you can, and I'll take 1,000 off your hands.
