Difficult chambering

[SSShooter]

Yes. Some light work with a piece of 500=600 grit paper on the first 1/4" of the chamber may take care of the problem. If the OP can set the cartridge by using his finger it can't be that bad.

Do a chamber cast and do a little measuring to see where the problem is.

Thanks Glenn
I’ve paid just short of 1000 dollars for this rifle. I don’t feel that I need to correct
the problem that was created by the manufacturer. I will be sending the rifle back
to them to correct it. Hope they will do it the right way....Jim

May be a while before you see it again.

Yep. My Beretta O/U took a fair bit of time (3mon+).

Bear,

I've honed out dies using the method described above. It's not rocket science, and will be invisible. Just take a piece of 7/16" dowel, cut a slit ~1/2" deep down the middle, and chuck it into your drill. Slip in a piece of 400 or finer grit doubled, polish the first 1/4" for a few seconds, try case, and repeat as necessary until the largest case chambers.

By the way, that's probably just what a warranty center will do, except they will probably polish it oversize.

Bear, I may have missed it but did you mention what bullet you are using? I had the same problem with my Shiloh 45-90 and it was the bullet I was using and not the die. I was casting a Lyman 457125 500 gr. Govt. bullet that was out of round. I didn't realize it until a few folks on this forum and Kurt told me to check the bullet mold. Sure enough, it was the mold. I did the fix on the mold but will not use it for now. Ordered a SAECO 1881 mold instead. Some of the rounds chambered but many didn't.

I have a Uberti 1885 45-90. Besides the brutal recoil, I like it because it is light and will chamber anything I put in it. When the round wouldn't chamber in the Shiloh, I put it in the Uberti. By the way, I don't like the Lyman dies either. Will be replacing them with Redding dies down the road.

You missed the fact that the OM found that a NEW, Unfired Empty brass also would not chamber easily
Its the chamber- Too darned tight at the base area

Yes I did. Sorry about that. That is strange that the Uberti would have that tight of a chamber. Mine is not and will shoot any bullet or 45-90 case I put in it. Unfired or fired. Definitely send it back or find a competent gunsmith to look it over good.

[Lumpy Grits]

Have you tried a loaded factory round?

[bear-kodiak]

Yes same result with a loaded factory round.

Another bargain,

That wasn’t such a bargain after all.

When I make a reamer for a wild cat case I cut the chamber in the rifle, then use the same reamer to cut the sizing die. Obviously the die of the same size as the chamber will not reduce the brass size without some help. This is where the fire formed case is turned into a chamber lap and used to enlarge the barrel chamber a few ten thousands so the die will size down the brass enough to chamber easily. It will in fact be almost a perfect match made fit for minimum brass expansion.
One of my martini cadets has such a wild cat chambering and die set up that works very well.

[Kurt]

When I have a chamber reamer made for a obsolete caliber I have two made, one for the chamber and one for the sizing die that is a couple thousands smaller.
I don't know what Bears rifle was chambered with but I wonder if they used a roughing reamer and forgot the finish reamer or the reamer was dull. With as close the chamber is I think a careful polishing using oiled 600 grid wet dry paper or emory would get the job done.
With the slight scratch marks on the base of the case might be from chatter from something being loose with the chuck holding the reamer.

[mdeland]

I've read that typically commercial sizing dies will be about .004 smaller diameter than will be the chamber but this is so any brass no matter how thick or hard will be sized down enough with the brass spring back to a the standard chamber. One does not need nearly that much resizing if any to make the cases fit the chamber the brass was fired in especially with these low pressure loads we use. Most of us do not really need to resize at all and would be better off without it as far as case body fit goes. We mostly just need the necks to be snugged and uniformed a bit after being fired for consistent bullet fit.
