Model 1889 choke determination

Post by No Deer » Sat Jun 22, 2019 8:36 pm

On the Model 1889 it has the 2 digit numbers stamped on the barrel lugs. I see in the Remington Shotgun Doubles book they have a chart on page 262 showing the number under a percentage heading for different sized loads. My question is, how do the percentages relate to choke? There are 3 columns, 40%, 60%, and 75%, are these supposed to represent cylinder, mod, and full? And if my percentage is say close to, but not in the 75% column for instance, is it improved mod? I have read and reread this section, and I just don't fully understand. I am a long time muzzle loader shooter and relatively new to modern shotguns (1889 is modern to me LOL), and I am trying to learn these types of things.

Thanks for any light you can shed on this for me.

Remington would usually stamp three character numbers on the lugs to indicate degree of choke. If only two numbers are stamped a leading 3 is assumed. Remington used a load of 1 1/4 oz of #8 shot (511 pellets) to target a 30" circle at 40 yds. So divide your stamped number by 511 and you will have the percent pellets in the circle and the degree of choke.

Modern shotgun chokes use to change every .005 of the muzzle being smaller than the bore.
.005=skeet
.010=IC
.015= L. Mod [ or years ago skeet out ]
.020=mod
.025=imp. mod.
.030=full
Now a days there is also lite full, extra full, turkey - some call .030 lite full and .035 full, .040 extra full
There's also a skeet 1 and skeet 2 - usually .005 and .008 - could vary.
So yes, your choke could be in between.
