Hi Orlando,

You are always a help with clear & factual info. for all of us on the CMP site. At least four of the rounds were from 1962.... I know some were 1971! The cases are still in the car!

This issue seemed to occur with my M-1's once or twice in the past.
Guess this 03 A3 rifle is just tight chambered!

Sir, I think this is the third time, you were kind enough to take your time to reply to my questions over the years.

Big Thanks for the reply,
broom

Sorry I didn't have the lot numbers, I ended up seeling it dirt cheapjust to get rid of it as accuracy was so poor

Hi Sir,

I'll check out & sort all the Greek I have left! I knew the gun-smithing was done correctly. So it could only be the ammo! I can live with a tight chamber!

I did not know the amount of out of spec ammo was as large as I have now found out!

Thanks for all your help this time & in the past,
broom

Hxp77 can have long cases. Usually not a problem but if you have any I would check it.

Hi All,

From what I see with from the random selection of various years of Greek manufacture HXP.
The cases gauge correctly (over all length) in a Wilson case gauge.
The rub is apparently is, the case diameter size from the shoulder taper to base of case is a few thousands over spec. I'll use a black magic marker on a few cases.
Apparently, it's not a problem in most Garand's or wartime manufactured 03-A3 barrels. We know they are usually oversize, so the rifles will work in adverse battle conditions!
I have no accurate way to check my new CMP Criterion barrel against a NOS Remington barrel or the original 1918 1903 Springfield barrel.
Which eats the slightly over size case with no problem!

I thank all of you posters, for sharing your knowledge with the rest of us,
broom

Lot numbers (or date stamps) will not help you. The trouble is quality control and defective cartridges will appear anywhere. The usual problem is excessive base to shoulder length, not case length or overall length. There may be some problems with case diameters or extractor grooves, but overwhelmingly, the problem is "case headspace". If new cases will not allow full bolt rotation, but extract rather easily you have a HS problem. Cases that extract with great difficulty usually indicate excessive case body diameters. Obviously, your chamber dimensions play into the situation. BTW: the finish reamer determines chamber dimensions....not Criterion. A 30-06 body sizing die is easy to make and use. It will solve HXP dimensional problems. Good Shooting. ...

Hi ceresco,

I will make up a gauge using a barrel stub from a shot out Remington 700 or a stub from a drill rifle barrel!

- fartblossom1953-idea for a gauge looks like it will work well!
It works for him! I hate to try to reinvent the wheel,so I will gladly use a proven idea!

Your comment on the finish reamer makes perfect sense, I really had not given it much thought! You have increasing my firearms knowledge

Thanks for your reply,
broom
