R&D Cylinder Question

[Mogorilla]

I have found my R&D cylinder is picky when it comes to 45 colt ammo.  Some just will not seat in the cylinder enough to get it back into the frame. 
Question 1.  does anyone else have this issue?

In shooting at the range yesterday, I tried some new ammo, Hornady Cowboy Ammo, 20 rounds to a box.   They were really consistent, a bit hotter than I normally shoot, but real accurate for factory ammo.  I am talking me shooting, and they were all 2inch groups.   Problem is, it was dirty and in dirty, I mean I thought I was shooting Black Powder.  After shooting 1 box, cylinder was a mess.  I had a box of 50 of the Winchester Cowboy ammo.  I only got about 30 of those shot due to the cylinder not accepting any due to fouling (left my cleaning kit in a different bag.) 
Question  2.  Anyone else had this issue?

Question 3.  Anyone ever polish the inner chambers of their conversion cylinder?   If so, can you give me a brief explanation/direction to do this?   I have a dremmel, but view them like a belt sander, great tool, but great potential for harm if done incorrectly.   

Thanks.

#1 - I occasionally run across a round that won't chamber properly. Generally it will have a slight bulge near the rim. I just grab a different round load 'er up, and don't sweat it.

#2 - I don't shoot factory ammo.  I do shoot BP, and have never had fouling build up in the chambers. (The cylinder pin's a different story!)

#3 - Using a hand-held-difficult-to-control-metal-removing-demon-tool on your expensive precision-machined part?

What could possibly go wrong?

came to the same conclusion after reading my posting.  Called Taylors, should have called them originally.  AWESOME CUSTOMER SERVICE!   Sending the cylinder back, they will make it right.

The issue with the rounds chambering is that they have been previously fired in a "looser" headspace firearm.
There is a slight bulge very near the base. The conversion cylinder has to full seat the round & this the headspace is a bit tighter.
Most folks notice the remington's turn into tack drivers with conversion cylinders...this is one of the reasons why.

You MIGHT be able to set your resizing die down a tad...this may help a bit. Another plan is keep brass for these revolvers away from your rifle.

Watch out for too much crimp, too...could raise a slight bulge & cause difficulty. Did I mention these cylinders are generally tight

Yep, I had the same problem with the R&D,,, I started using a 454 Casull resizeing die and then resizing again with a 45acp die to get the resized portion closer to the rim... after this treatment my brass was back in action and did not need this done again as long as I stay with normal 45 colt loading. I had previously tramatized my brass using it for Hi-Pressure loads in Freedom Arms revolvers and 360gr hardcast slugs.

Thanks for the replies.  Actually I have only shot factory brass in this.  I am just starting to read about reloading, and am looking to start.

I had a similar problem.  Through a little trial and error, I figured out that in my reload process, I was flaring the case to much.  I backed off on that die and everything chambers fine.
