Bullet Cannelure

When loading bullets that have a cannelure do you have to seat the bullet so that the edge of the case neck in the cannelure when shooting a bolt action? I have some Hornady bullets that i want to try and i like to seat as close to the lands as possible and when i do the cannelure is out past the edge of the case neck, is this ok? Thank You!

It is ok as long as you don' t crimp.

Mykey,

It is not necessary to crimp a case just because the bullet has a cannelure. Seat the bullet to any length you want. Good luck.[&:]

You know talking about crimping. I have been playing alot with my chrono lately. I shot some grandslams loaded with 95gr of H1000 and loaded to a COL of 3.65" which is well past the cannelure. I then use the same load crimped at the cannelure loaded to 3.55" . Wow, what a difference it made in pressure.

the long ones shot 3150fps, the short ones crimped got 3320fps. Thats huge.

Actually, some things like the Swift A-Frame, I see shoot well with a crimp, but the guys at Nosler and Sierra don' t recommend the crimp. Those are some sharp dudes on thier shooting. These GS don' t do well for me with a crimp. Actually they don' t do much for me without a crimp.

DG I usually dont crimp except with 45/70' s but what you are saying does make sense especially with magnum calibers...BigCountry I didn' t think that Nosler or Sierra put cannelures on their bullets anymore unless they were special order. I have never crimped them either.

Yes the Cannelure has another benefit as well.....it helps hold the lead in the jacket.

I shoot a .375 H&H and don' t crimp them.....now if I was going after dangerous game I' d probably do it as a precausion but it' s just plain not necessary.....

The recoil has a tendency to bung up the bullet points and that can be a bad thing for accuracy.....I suggest using a " protected point" in the big guns. Heck even my .270 damages the soft points in the magazine.

As far as accuracy.....you must try them both ways and determine for yourself.....I' ve never found a statistical difference.
