I basicaly target shoot as I have killed enough deer, don't need to shoot any more.
Does the Cannelure help or hurt with target shooting. I bought some Spire points from Hornady.with it.
Thanks Bill

I have some rifles that shoot the Hornadies better then any other bullet. Then there are others that like Sierras or Noslers, bullets with no cannelure the best. I doubt you can tell without a benchrifle and the ability to use it if one without a cannelure out shoots the other for everyday target shooting.
I haven`t seen a bullet, custom made for benchrest shooting, though that has a cannelure. That might say something.........JMO

In MOST instances a cannelure is a bad thing as far as accuracy goes. They take a great bullet and roll a cannelure into the surface, this displaces the copper and the lead underneath. The lead stays and the copper springs back slightly. This leaves a small gap (not really a gap but a difference in tension) between the copper and lead compared to the rest of the bullet. Some of the copper is displaced outward making the diameter larger at that point.
In most instances, from a machine rest, groups will be larger after a cannelure is applied to a batch of bullets.
If I were going for group size only I would avoid a cannelure unless it was necessary to keep the bullet from moving, as in a semi-auto, pump or revolver.

Buy Hornady's A-Max bullets and look for the cannelure.....it's very hard to find.
Mostly the cannelure is a place to crimp the case to.....and that makes the bullets primarily hunting bullets and further the cannelure helps lock the lead to the jacket to prevent loss of the lead during impact.....all in all the cannelure don't help accuracy but it's presence don't necessarily assure poor accuracy either.

If I'm a strictly paper puncher I don't want a cannelure.

Cannelure may be detrimental to benchrest accuracy, but IMHO, is not important to the "cross the coarse" target shooter or hunting accuracy.

As far as crimping for semi-auto rifles is concerned, I have not found it necessary in either the M1 Garand or the M14. The bullet will not move in either of these rifles. I have found it necessary to crimp for the 375 h&h, however.
