Remington Small Rifle Primers
I do hope this is not old news, but here in the West it seems to be not too well known that there is a SAFETY Warning on Remington Small Rifle Primers that reloaders should be aware of.
Last summer when (Remington) primers started to become somewhat available - other brands were not, the Sportsman Warehouse chain had a posted warning to the effect that Remington 6 1/2 primers were only intended to be used on cartridges such as .30 Carbine, .22 Hornet, etc.
The sign specifically noted also that these primers were NOT to be used for loading .223 and similar cartridges. I asked various sales persons what the deal was, but none of them seemed to know anything other than what their sign stated. I thought maybe this was just another rumor in the category of "primer scares".
I finally got around to doing some more research and found similar warnings on MIDWAY and MIDSOUTH websites, but what hit me the hardest was a posting on one of the other forums where the member said something to the effect of "Hey Dummy, the primer warning is printed right there on the side of the box!" Well, I guess it is, but you better get out your magnifying glass in order to read the fine print - I couldn't read it even with my reading glasses.
Apparently, using # 6 1/2 primers in .223 and similar high pressure cartridges will result in pierced primers and possible damage to your rifle. Use the # 7 1/2 Benchrest primers for all High-Intensity cartridge loading.
