ok i full length resized some casing. they fit great in the gun then i loaded a few and the fit tight when the bolt was closed what did i do wrong??

Are you saying that you full-length sized them and then chambered them BEFORE you charged and seated the case and they fit fine, but after you charged and seated the bullets they chamber hard?

If so the first thing that you should look at is your cartridge overall length (COL). It sounds like you haven't seated the bullets far enough into the cases and the bullet is firmly hitting the lands in the bore when you are chambering them. Often when this happens the camming action of the bolt will have enough force to push the bullet back into the case enough to allow the bolt to close.

DO NOT FIRE THAT AMMO!!!

Because the bullet is firmly jammed into the rifling, effectively creating what is basically a bore obstruction that will cause the pressure levels to spike to dangerously high levels possibly resulting in damage to your rifle and serious bodily injury or death to you and any bystanders.

Check to make sure that the bullets are seated to the COL depth stated in the load manual FOR THE BULLET THAT YOU'RE USING. The published COL is guarantees that the bullet (with its perticular ogive shape) will not contact the rifling in a chamber cut to SAAMI specs. If you have already seated the bullets so that they are at the published COL and they are still hitting the rifling, it could be that the throat on your perticular rifle was not reamed deep enough to meet SAAMI specs. At that point I'd either take the gun to a 'smith to have him cast and measure the chamber dimensions (which is the safest course of action), or you can take the riskier route and seat the bullet slightly deeper until the round chamber easily. You will, of course, have to reduce the starting loads by 10-15% and work back up because a deeper seating depth will increase chamber pressures. If you choose the second course of action you do so AT YOUR OWN RISK.

Oh, and one more thing. How are you measuring your cartridges? A caliper accurate to .001" is really a must, especially if you have a short throated chamber. 0.001-.002" can make the difference between a bullet seated to close to the rifling and a bullet seated at optimum seating depth. If you don't have a caliper (dial or digital is your choice), get one. They are worth the $20 investment (If you want to save a bit of money, avoid buying the brand name calipers marketed by the various reloading tool companies like Lyman, RCBS, etc.... They are fine calipers, but you'll pay more for a virtually identical product probably made in the same factory than if you buy an offbrand from one of the online tool distributors. Just a thought).

Good luck and stay safe.

they are not hitting the lands they are set .050 under what the book calls for it seems like the bullit is bent..

What's the caliber?
What are the dies. Could they be Hornady?
Did you lube the inside of the case neck before sizing?

Have you come across a problem with the Horn. rounds?
I have been using them now for about 8 years and never had a problem with them. I you have I would appr. the imput.

To me the Horn. bullets are SOME of the best bullets that I have ever used.

Sounds to me you do not have your dies adjusted in accordance with your ram so when you seat the bullet you are very possibly bending or warping the neck of the case. To add if the round does not chamber smoothly DO NOT SHOOT IT. Damaged cases can have a adverse effect when fired could possibly damage the gun. not to mention horrible accuracy

My question

I never asked what his projectiles were.

If your seating that bullet wrong or your dies are closing the neck too much, your bullet could be cantered a tad.

Run your case thru the die without expander. Measure the inside and outside of the case with calibers. Next run it thru the expander. Do the same thing again. Next, load the round. What you should see is something like this.

For example. 308win

Fired neck inside:310
Sized neck inside:.303 maybe .304
Ran thru expander:.305 or .304

You can check your expander ball with calibers too to make sure they are in spec.

Another thought...

Your seater die may be misadjusted. Do you have your seater die set to crimp the mouth of the cases? If so, and you are using non-cannellured bullets, you would be causing the die to create a slight bulge around the mouth and neck which would make chambering difficult if not impossble.

check the length of your brass too, it might need to be trimmed- when you resize a cartridge the brass gets squeazed and has to go somewhere if you are shortening the headspace of the case- the extra length goes on the neck.
