reloads not chambering??

[rosewood]

I don't think anyone else mentioned it, but is it possible you are slightly bulging your brass? If the crimp/seater dies isn't adjusted properly, you can bulge the brass.

The kerplunk test will be a good way to narrow down the issues. If the problem isn't obvious, you can mark the completed case with a blue sharpie and drop in the chamber, pull it out and see where the sharpie rubbed off.

Double check your OAL and run them through a taper crimp die.

Initially I had not ran the sizing die down far enough. This why I removed the decapping portion. I thought I had fixed the problem. I'm going to recheck my seating die. I'm thinking that the seat is too far down and not letting the die fully crimp the neck. The bullet is seating to the cannelure and the OAL is fine. try, try again.

You can tell anything you want to know about reload fit with a sharpie. Just work fast before it dries. My guess is you’ll see a smear on the olgive do the bullet.. but that’s just a guess.

Always do this when switching to a new bullet profile or new barrel:

Setting the "best" OAL for your gun involves ensuring that the loaded rounds

fit through your magazine and slide easily in and out of your chamber.

Once you've set the "crimp" properly, the only component left is the

OAL. So, first set your crimp properly, and then leave it alone - no reason

to change it once you've removed the belling and the rounds chamber

properly.

Set your OAL for the longest recommended - then try The Plunk Test -

remove the barrel from your gun, and drop the loaded round into the

chamber.

The cartridge should fall all the way in, without any pushing, and spin

freely in the chamber, and drop freely from the chamber if you turn the

barrel upside down.

IF IT WON'T SPIN OR DROP FREELY, YOUR OAL IS TOO LONG

FOR THAT PARTICULAR BULLET IN YOUR GUN.

If your OAL is too long, you have to shorten the OAL, and try it again.

Once you've found your longest possible OAL for your gun, then you

shorten that my .05" and load up 10-20 rounds and try them - make

sure they all will spin freely and drop out of the barrel easily. If you get

any that are too long, try shortening the OAL a little bit more.

FAQ'S

1. "I ran the drop test, and my rounds are still sticking in the chamber"

- shorten the OAL

2. "But the longer rounds feed perfectly in ....... gun".

- Great. But not in YOUR gun - shorten the OAL.

3. "But I load 124 grain MG FMJ's at .... OAL, and these BBI 124 gr

bullets don't pass the Plunk Test".

- Exactly right. Now you have to shorten the OAL of the BBI bullets

until they pass the Plunk Test

4. "But I'm at ...." OAL, and don't want to go shorter".

- Fine. Use another bullet. But if you have 1,000 of these new

bullets, they will probably work if you shorten the OAL until

they PASS the Plunk Test.

5. "But, I ran the Plunk Test, and they still don't feed."

- Exactly right. They will NOT pass the Plunk Test until you

load them short enough to drop freely from YOUR chamber

6. "But, the manual says to load them at ...." OAL. And they

don't spin/drop in my chamber".

- Exactly!! Drop the OAL, shorten the rounds, until they PASS

the Plunk Test.

7. "It is really important to me to run these long cartridges in my gun,

but they won't feed"

- Buy a new gun, have the chamber reamed or shorten the OAL.

8. "I ran the Plunk Test, and they don't feed. I think the bullets are

oversized or I don't have enough "crimp".

- Set your crimp 1st, then measure your bullets - doubt any major

mfgr of bullets is selling incorrect sized bullets, but it's possible.

Shorten your OAL until they feed.

9. "Man, that's a Lot of Work".

- Welcome to the wonderful world of reloading.

10. "My buddy has the same gun I have, and his cartridges won't

feed in my identical gun".

- Sorry, guess they're Not Identical. Shorten your OAL and

try the Plunk Test in Your Gun.

11. "But, if I shorten the OAL, won't that affect pressure / velocity"?

- It might. You must test each change (OAL, etc) for velocity

and watch for pressure signs on the primer.

12. "But, this is a Great load - really accurate at ...." OAL - but it

won't feed. When I shorten the OAL, it's not as accurate."

- Up to you, if you want a very accurate single shot, go with

the longer OAL. If you want a reliable gun, go shorter.

If you want both (accuracy & reliability) try another bullet.

13. "But, I'm going to a major match tomorrow morning, and

my favorite load won't spin/drop".

- Too late, procrastinator. Bring along some already

tested rounds that work in your gun, and when you get

back from the match, work on the proper OAL for your

new bullets.

14. "But, my rounds all pass the gauge test from EGW".

- Unless your gauge has a 5" barrel, I'd test your rounds

in the chamber of the gun you're going to shoot. If

they don't pass the Plunk Test in YOUR chamber,

you have to shorten the OAL.

Sorry for being so long-winded, but every other day we get one

or more of these excuses why members can't feed rounds thru their

guns.

It's an OAL problem and has to do with the olive of the projectile. The crimp doesnt have to do with going into battery. Take an empty brass, seat the projectile into it with no crimp and slowly see if it goes into battery. If it hits the landings too soon, seat it some more until it goes into battery. Omce you have the right OAL crimp it, and then you have a jig to set up all your dies from that point on.

size your brass all the way down. get/find the correct OAL. don't base your OAL on the cannelure. find the correct OAL by making test rounds. seat bullet - step one, then taper/factory crimp - step two.
