OK...its hard to see on a couple of these rounds, but its there on all of them.

The 2 on the right will chamber in my AR 15...but not my match grade bolt actions...these are some rounds that my son goofed up while I was teaching him how to do this...I kept them for visual aids.

Do your rounds look like this?...look close...

Ridgerunner posted an excellent pic. Sometimes the flared shoulder is hard to see but it can usually be felt.

When in doubt, use your micrometer to check.
 
Buy a cartridge gauge from Midway (or wherever), and adjust your sizing die until your brass fits ('chambers' in) the gauge.

This is the best answer given.

These kind of problems are usually related to the way you are sizing your brass. If you don't use a case gauge, you are just guessing.
 
What bullets are you using...do they have a cannelure?

Its VERY easy to over crimp bulets that don't have a cannelure...like the 50 grain Nosler Ballistic Tips which are the 2 bullets on the right in that pic.
 
Don't crimp them at all and see what happens...they don't really have to be crimped for a bolt action anyway...just work the bolt a little easier and don't ram it home.

I still think you are crimping too tight...but I may be wrong.
 
ok ridgerunner i screwed the sizing die down to the shell holder instead of just above the rim as before. i sized on and loaded it as a dummy round it chambers great now.

thanks for the help guys
 
mlw...

Loading for rifle is where you want to get everything very precise...it don't really matter with pistols...but it does with rifles, the farther you shoot, the more it matters.
 
What rate of twist is your barrel?

I get decent accuracy from my AR at 600 yards with heavy bullets (I can keep them all in an 8 inch circle), its not a varmint rig...just a plain old Smith & Wesson M&P 15 with a 3-9x40 Leupold scope on it.

It is pure destruction for coyotes at 300 yards with those 50 grain Nosler Ballistic Tips launched at 3,100 fps (.75" groups @ 100 yards)

1 in 9 twist barrel and it shoots REALLY good with 62 - 70 grain bullets.

Only 1 model of Remington 700 in 223 has a fast twist (1 in 9) barrel...I don't remeber the exact name of it, but its the tactical rifle (20 inch bull barrel).

If you have a 1 in 12 twist you will have better luck at 300 yards and less...because it won't stabilize the heavy bullets needed to reach way out there.
