Model 572 "Choke Bore"
I posted on this about 2 years ago, but never got a very good answer. I have this 572 that is marked Choke Bore,, It appears to be the Routledge type bore, its about .400 diameter at the muzzle then about half way down the barrell toward the chamber it constricts down to regular .22 size smoothbore.. Is there any difference between Choke bore and Routledge?? Anyone know for how long they marked them this way, or why... How does this pattern compared to a regular smoothbore???? Sure is deadly on woodboring bees!!!!! My guess is they used .410 reamers during the manufacturing operation, Don't have any inside calipers, so I don't know if it actually has any "Choke" in it at the muzzle, but sounds feaseable... Does John's book have any info on these???? Thanks..
Sorry you didn't get a "Very good answer" two years ago. If I answered, I probably gave you all the info I had at the time. You didn't ask easy questions....
We have a fair amount of information on the various smoothbores in the book, but did not answer all of your questions specifically.
From what I can tell, the M/572 choke bore had the same dimensions as the Routledge. The muzzle end is .40". I don't believe any additional "choke" was used.
Prior to 1956 the M/572 was stamped ROUTLEDGE BORE.
By January, 1958 CHOKE BORE was stamped.
In 1973, the stamp was .22 LR SHOT CARTRIDGE
In 1974 it was changed to SMOOTH BORE.
The M/572 smooth bores were discontinued in 1979, but were re-introduced in 2004.
I believe they were all the same configuration, with the exception of barrel length which was shortened from 23" to to 21" in 1978.
Hope this helps. John Gyde

John, thanks so much for the info... Couple of years ago, I e-mailed the lady that is supposed to be remingtons historian,, I knew enough to tell from the answer she gave me that she didn't have a clue.. she said something to the effect, that smoothbore, and choke bore were used interchaneably,,,, maybe she meant Routledge and choke bore... were some of them marked MoSkeetO too??? Thanks again John Hopefully I can scrape together enough to buy one of the new for this year smooth bore 572's and I can do my own pattern tests...But if anyone knows how the two (Routledge/choke bore, ) compare to straight smoothbore, please chime in.......THANKS
The "MO-SKEET-O" designation was used on the M/121 and the M510. I don't believe it was used on the M/572. All of the designations usually meant the same thing. The only exception I can think of is SMOOTH BORE, which (I believe) was used for a straight through bore as well as a Routledge configuration.

John, I just now read your second reply... yes I bought it....and no the guy was exzagerating quite a bit about the 8" pattern, but it is a very uniform pattern at longer ranges,, amazing compared to a shot out of an old rifled 510. I can kill the bees consistently at at least twice the range as from a standard rifle... its been 2 years since I did the patterning, and don't remember the details... but I will maybe do it again sometime and post the results,,,
