Cannelure or not??????

[Lee Whitsel]

I can't find the bullet I like to use. But I can find it with the cannelure on it. For gopher shooting will that have any effect on accurate of the bullet? I always use just the jacketed without the crimping groves. Any help??

Greetings,
I guarantee your rodent targets will not know any difference between them.

Agree with bpd459.

I once ordered a supply of 55 V-Max bullets many years back, and I ended up getting ones with the cannelure, which was in error. I figured I'd give them a go. I found they didn't shoot quite as accurately as those without the cannelure, yet they were still pretty good. I used them until the non-cannelure bullets were available again - and the rest of the cannelure bullets have sat on my shelf since then. I'd not hesitate to use them on coyotes or close-in gophers (say, within 300-350 yards or so), but past that, you will likely see more unexplained misses. Still - missing a few more here and there isn't a big deal when there may be hundreds of new targets popping up. There was a difference on paper as well - but not significant enough to not use them. And if they are good enough for those tiny gophers - they are more than adequate for anything bigger -

A cannelure is ther for one purpose, to serve as a positive lock for a crimp.

This if course is nessessary in some high recoil applications where cartridges in a magazine, or revolver cylinders , can have their bullets move forward upon the inertia of recoil.

Most 22 caliber cartridges do not exibit that degree of recoil.

I guess your best option is to invest in a box and see if you carmaker them perform within the limits of your expectations.

Cannelure doesn't matter for practical applications, like gopher shooting. Also, .003"-.004" neck tension accomplishes the same thing in an AR15. Just ignore that it is there, and don't bother setting your seating depth to the cannelure groove. Seat your bullets to length that you normally do for your rifle.

It is handy (belt and suspenders) for military applications. Concerns around rough treatment of ammo in a semi-auto.

With "enough" neck tension, a crimp isn't needed. Just seat past the cannelure. No problems with my M1A or my 44 Mag Super Blackhawk.
Bullets won't move till fired.

I shoot 154 gr Hornady round nose bullets in my 7mm. Rem Mag for years. They had a crimp cannelure. I didn't crimp . They shot very smal groups.
