Scott_r: My gawd man - what world do you live on?
I have NOT seen a small Rifle primer on a store shelf in many months now - and that includes store shelves in 5 western (U.S.) states!
I have been loading Federal 205M primers in all 5 (five) of my 204 Ruger calibered Varminters for 5 years+ now and have as yet to pierce a single primer!
I have complete confidence in them.
Again if you should choose not to buy the Federal 205M primers PLEASE give me the co-ordinates on where to get them!
Best of luck with your choice and your 204!
Hold into the wind
