I am just starting to reload ofr my ARs. I never thought about getting specific primers for it. I have a couple thousand Remington Small Rifle Bench Rest primers. Any reason I cannot use these? I dont want to have to try to find CCI 34 or 41, whichever it is, specific AR primers. |

Quoted: Your Remington 7½ primers are great for precision stuff. I use them with TAC and 68grn Hornadys for 300yd shooting. My 55grn ammo gets Winchester SR primers. yeah, I am trying my hand at loading for precision. I have a box of 69 SMK and some Varget. I have a 1:7 and 1:8 twist I want to see what we can do. I was just concerned that the SR BR primers may be too soft, or not hard enough for a mag fed weapon. |

223 Primers for AR
Wolf=Small Rifle Magnum or the "223" Primer which I have never seen. CCI=400, 450, BR4, and Mil Spec 41 Rem=7.5 Fed=205, 205M, GM205 Win=SR MagTech=Small Rifle Rem 7.5 works great with Varget, RL15, and TAC They have usually been readily available so that is good point to remember. |

The "thing" about Rem sm rifle primers and using them to reload .223 Rem/5.56 ammo had to do with Rem 6 1/2 primers..........
And, Remington says……… http://remington.custhelp.com/app/answers/detail/a_id/167 In rifle cartridges, the 6-1/2 small rifle primer should not be used in the 17 Remington, 222 Remington or the 223 Remington. The 7-1/2 BR is the proper small rifle primer for these rounds.
Warning: When primers are selected incorrectly, misfires, damage to your firearm, and/or personal injury may occur. Visit the ballistics tables on our website. Recommended primers for each rifle and pistol cartridge are listed in these tables. Aloha, Mark |
