.45LC load jam in Krist Konverter

[sandy4570]

I just try my Krist Konverter cylinder .45 LC in my Uberti Rem new army 58 "Millenium" .The load I use were 35 grain Pyrodex P and 200 grain mieser bullet lube with SPG and 30 grain of Pyrodex P toped by 250 grain RNFP Mieser bullet also lubed with SPG. After the first shot the hand will not rotate the cylinder and it have to be rotate manually for the next shot.I e-mail river junction and Walt Krist replied that it might be the black powder and pyrodex fouling symptom because the cylinder gap of this conversion is very tight and it will work fine with smokeless powder but not so with black powder . He recommended that I have gun smith grind down a few thousand inch off the cylinder chamber. I would like to know if there is an alternative to this because I know if I have this work done the cylinder gap will be too much for the smokeless round and accuratcy will suffer ( and it is very accurate indeed , especially with 250 grain black hill load) .I also believe that it might not be just the cylinder gap but more on the heavy load of the round I use. I just read that even the army back in 19th century back the load down from 40 grain to 30 grain because soldier couldn't handle the 40 grain recoil and that the civilian load is only 35 grain. I assume that Pyrodex will give slightly more velocity so that my 35 grain is really more or less a 40-45 grain black powder equivalent? Does anyone here using black powder or pyrodex load in the cylinder conversion Remington and have the same problem ? what is your recommendation ? I load down my next batch with 20 and 25 grain of Pyrodex and fill up the air space with corn meal and plan to test them soon.

If your cylinder gap is too small you will always have trouble with cylinder binding using BP and smoky substitutes.

The original .45lc load was 40 grains of BP. The case capacity has dropped to somewhere in the high to mid 30s because we stopped using balloon head cases. I believe the 28-30 grain load is what .45 schofield uses and that may have caused the military spec since for a while they were using both rounds in the Colt SAA.

Thank you for the information. I happen to have a Pietta Remington on hand and the Uberti cylinder fit the Pietta with plenty of room to spare with very generous cylinder gap.I e-mail Walt Krist about this swaping if I can drop the Uberti cylinder into Pietta for use with black powder and Pyrodex without any ill effect , if this work out then I don't have to spend anymore money on gunsmithing modification and still keep the cylinder gap with in spec for the smokeless stuff. Only thing that I am worry now is that little gap on the cylinder and arbor pin mean that the cylinder might be slam back and forth agianst the frame and might damage something so I better wait for the approval from the maker of Krist cylinder first.

You may have primers that are not fully seated, if You have problems after so few rounds. I shoot 50-70 rounds of B-P without cleaning W/ only .0064 and .0057 clearance at the barrel to cyl. on 2 different Rugers. I also use wads ,cut .452 from notebook backing, to fill any space. I load 38grs. Pyrodex or Goex B-P, W/250grn. RNFP solid lead W/a beeswax & Virgin Olive oil lube. The 250 grn. compresses the Pyro. or the B-P about 3/16 to 1/8 inch. I don't care to use any filler. Use a good crimp to allow time for the powder to build some pressure. You don't want to load too light, as you may get some squibbs W/ the low pressure B-P loads. Good Luck, S.R.

Smoke Rizen Thank you kindly for the information.I just recieved approval from Junction river to use Uberti cylinder on my Pietta revolver this should allow the cylinder to rotate with some fouling. I will have to try the 20 and 25 grain Pyrodex load soon . I still believe that 30 and 35 grain load might a bit too much for Remington.
