Remington ………the revolver of choice

Euro arms may indeed have offered the Lothar-Walther barrel on their target 1858. I can't confirm from personal knowledge.

This chamber reaming that is so often advised can be very dangerous. Especially in older Piettas with substantially underbore chambers. Chamber wall thickness on some cylinders is marginal, especially on the likes of the old ASM. They made a pretty gun but made them from a chocolate and tin alloy. Reaming such chambers even 005. - .006 represents a serious risk. Further, a chamber that is .003" or so under groove diameter is no great issue. While the inverse is to be desired (note ROA specs above), using appropriately soft lead BHN 8 -9 will allow for sufficient obturation with any 25 gr BP charge to fill groove diameter.

If the chamber diameter is more than .005" under groove diameter, that gun is a novelty item and noise maker and getting it to shoot somewhat accurately will be a labor to say the least.
 
.457 RBs are the normal load for an original Remington...and the original guns may have been the most accurate service pistol ever issued. An original in good shape will hold 13 shots in 2 inches or less at 25 yards.

It shouldn't be if one uses reasonable judgment concerning the platform they are working on in the first place. Also the chambers should only be reamed to ball seating depth, and under no conditions should it go deep enough to cut under the bolt notches in the back.

It has been my experience that when the chamber swages the ball to .002-.003"" over barrel groove diameter you'll get most of the best accuracy you can from that particular revolver. Changing the barrel to match the chambers is also an alternative to reaming, but you may have to go to Europe to get the barrel blank.
 
Your Colt 1860 replica may need a chamber reaming job and a little work on the action/trigger pull, but I can assure you that any big groups are not the revolver's fault. Been there/done that.


I agree there 100%!!!

Also Sir, the reverse is true, whenever I heard a "good shot" I would always remind them, "heck, I was just the dummy pulling the trigger it was the rifle (or revolver) that did all of the work" :)

With this I must concur.
 
I can't verify this as I don't compete in these type of matches but the Pedersoli built Remmy is doing well also in international competitions. But, I don't know where someone can buy them here in the States.
 
Pietta may provide Pedersoli with the rough forgings, I don't know. I had a Pietta 'Target Model' not this 'Shooters Model' back in the 80's that had an adjustable rear sight mounted on the top strap but the front sight was fixed. I remember though the sight was real sloppy and the sight picture hardly precise.
