Question, cannalure or not? I've never seen any posts regarding the 22-250 and bullets with cannalures. So I have to ask is this a bad idea? Is there a reason against it, i.e. heavy barrel wear or something like that? Bad ballistics? Or have I just missed any discussions about it and they'd be fine?
Oh and I appologize in advance if this sets off some sort of flame war or something since I know belief or opinion driven topics can get heated....
Thanks,
Bill

Are you going to be crimping? The channel makes it much easier, but it's not really necessary. Shouldn't be a 'flame-war' anywhere on the horizon? We're not that type of crowd around here.......
Ballistically?? Seen some photos showing an addition shockwave coming from the tha cannalure, has to be some type of difference towards the negative as far as BC is concerned...
As far as preferences: I prefer 'Match' type bullet....not too many grooves in those.

Well I'm sure when I begin loading I will be crimping after a full length sizing. I'd imagine as I get the process down and I get comfortable with it I'll move towards collet and match type bullets.
I'm wondering because Midway has some 224's that come to 6 cents a piece but have a cannelure and it had me perplexed weather this was a good idea to use these for my introduction to reloading. I'm not looking for accuracy at first, just to build a good methodology, habits, and to learn what effect OAL, crimping, and charge have on trajectory. Obviously there are other considerations but I just wanted to make sure cannelure isn't/wasn't an issue in a 22-250.

I've shot both cannalured and plain bullets in my .22/250. I certainly can't see enough difference to start a flame war over!

Ok so you guys are more mature than others on other forums. Hey you never know, I've had a flame war erupt just from mentioing the words "label whore" on another forum.

I don't know that folks over here are more mature. I've always concentrated on "growing older but not up". (Sorry for the theft, Jimmy...). I can't recall ever seeing a real, honest to God flame war here, and I doubt you will, either. TG and the other founders, and the moderators, mostly don't put up with that kind of BS. We are ALWAYS going to disagree with others, no reason not to do it in a civil manner.Last edited on Mon Apr 9th, 2007 02:55 AM by Charley

C. I like your attitude about beginning. When I started my first was 9mm, next was 22-250. At first I was all about velocity, but now I am all about accuracy. Not benchrest accuracy, but the practical kind of accuracy that varmint hunters need. The most accuarte bullet I have found in my 22-250s is the Sierra 55 HPBT Game King bullet. I also like the Hornady 55 grain spire point, you can buy this bullet in bulk very reasonably, with or without cannelure.
Good luck, be safe.

When Lee first came out with their Factory Crimp Die, Blount Corporation, (RCBS), went all out in an expensive advertising blitz attacking it, along with their claim of "Overcoming The Factory Advantage," that Lee used in the advertising of the product. This went back and forth for several months with RCBS claiming it was detrimental to accuracy to crimp a non cannalured bullet which Lee advertised it would, and in fact did do. They, (RCBS) backed this up with testimony from Speer, RCBS's sister company. Lee countered with an ad showing factory Winchester .308 Match ammunition with a crimped non cannalured Sierra Matchking bullet, (the ad showed the disassembled components with the pressed in crimp on the Sierra bullet). Lee's sales went well for the Factory Crimp Die, and RCBS finally left well enough alone. I don't think it has ever been successfully argued either way. Personally I don't put "crush crimps" on non cannalured bullets. I just lightly bump them to give a little tension on the bullet. With cannalured bullets I do put a good, solid crimp on them. I think it helps give more uniform ignition with very slow burning magnum rifle powders. Bill T.

There is very little difference in the non and the cannalure type bullet except you can find the bullets with the cannalure a little cheaper. Just load them and don't crimp them and see if your rifle will group them. My only problem with cannalure bullets is sometime the bullet is deformed when the cannalure is applied to the bullet and this hurts their accuracy over regular bullets.

Depending on the powder type a crimp is not necessary(some powders perform better when crimped). Crimps become necessary when loading multiple rounds of ammunition in magazines, keeps those pesky projectiles from moving during recoil.
I've always had outstanding accuracy from H-380/IMR-4350/AAC-2520/Varget/BL-(C)2 and 55grainers. Mine really likes Bergers though! Good luck, let us know how it goes with those less expensive(didn't want to say cheap) bullets??

I've shot both types in my .22-250 but I've never crimped them. My gun prefers the Hornady V-Max with IMR4064.
