[QUOTE="bigedp51, post: 1131645, member: 28965"] Bart B The 22 caliber 77-gr. HPMK has a cannelure because the military requested it for their 5.56 mm, Special Ball, Long Range, Mk 262 Mod 0/1 ammunition. My blasting, end of the world, SHTF, Zombie apocalypse ammunition is "LIGHTLY" crimped and my match grade ammo is not crimped. If a reloader does not understand neck tension or bullet grip then crimping is not the end of the world as you stated above. So don't tell me a "uncrimped" full length resized cartridge has never had a bullet move forward from inertia when chambered in a semiautomatic rifle. All it would take is one neck on the thin side and then have a bullet "jammed" into the rifling and raise chamber pressures to dangerous levels. There is a reason "WHY" the military requested a cannelure on their bullets. [IMG]http://i122.photobucket.com/albums/o254/bigedp51/sierracrimp004_zps19c43ef6.jpg[/IMG] And there is a reason "WHY" RCBS has a taper crimp on their AR series dies. [IMG]http://i122.photobucket.com/albums/o254/bigedp51/dies003_zpsf9af9a52.jpg[/IMG] So all of you readers just remember this, the red tipped V-Max bullet on the left is fired in my bolt action .223 Savage and is not crimped. And the green tip Z-Max on the right is crimped for my AR15 rifles just like the military does. [IMG]http://i122.photobucket.com/albums/o254/bigedp51/VZ_zps4391ae19.jpg[/IMG] So again, there is nothing worse than a jammed AR15 rifle in a Zombie attack where only close range head shots count. [IMG]http://i122.photobucket.com/albums/o254/bigedp51/silhouettezombie_zps0faf3cdd.jpg[/IMG] And if you decide not to crimp then your going to have to make friends with the Zombies and do your postings at Benchrest Central. [IMG]http://i122.photobucket.com/albums/o254/bigedp51/walking-dead-hugs_zpsbr0ixkta.jpg[/IMG] P.S. I crimp my 30-30 ammo also, and range estimation isn't critical and crimping the bullets doesn't matter as long as you put the corn piles less than five feet apart. [IMG]http://i122.photobucket.com/albums/o254/bigedp51/deer_zps7c735c90.jpg[/IMG] So who does this Bart Buttzinsky think he is, and why is he crimping our style?
