Remingtons 1899's are very goodguns. I have 2. With all respect some thing with remingtons doesn't add up. With the choke dias shown by Silvres youu would expect to see more difference in the two barrels. 028 is light full choke and 037 is quite full. Remingtom may have rounded out the pellet counts to the nearest 10 meaninging 310 and 350 as said here by Ohiosam, Using 310 and 350 and 499 pellets the patterns are 62 % and 70 % and that is about right for the choke dias posted. I have read about dropping the leading 3 in the Double Journal stories but look at winter 2003 page 40. The lump stamps are 43-195 and the respected author says that is cylinedr and modified. Can someone do 2 calculations using those numbers that come up with 40 % and 60 % patterns as commonly used for cylinder and modified? It seems Rem may have changed the system somewhere along inthose years.
