Hi all,

I shoot my clays course with a 32 inch 12 gauge - skeet and IC chokes. Planning on taking the 30 inch 20 gauge up this weekend for a change of pace. Thinking about using lite mod and a modified for chokes, or is that overkill? Any thoughts?

Use the same chokes in 20 - if they are that close for 12 to use S/IC, the 20 will do the same

Thanks for the quick response, oneounceload. I'll give that a whirl. There are one or two targets that are a little out there, but I may be able to get by with a different load on those.

What oneounce said -- however, if you want to learn to shoot bette, choke up to the LM/M and focus.

I'd just drop down one shot size for my loads, and go with an IC and Mod choke. Use the selector switch for choke selection/ firing order.

The shot size drop (e.g. if you use 7 1/2s in 12, use 8 in 20, or 8s in 12, use 8 1/2s in 20) is for shot density on target, as is the chokes selection.

Here are a few of my pattern numbers showing the performance differences of 20- and 12-gauge chokes, with these factory loads and in these two guns anyway.

Patterning results from 20-gauge and 12-gauge Browning Citori’s with 28" Invector-plus barrels and Briley flush chokes (patterns average of five, 30" post-shot scribed circle, yardage taped muzzle to target, and in-shell pellet count average of five).

20-Gauge w/ 28" barrels
Winchester AA Target Load
7/8 oz #8 lead (356 pellets) @ 1200 fps
30 YARDS -- CYL / pattern 182 (51%)
30 YARDS -- SK / pattern 230 (65%)
30 YARDS -- IC / pattern 257 (72%)
30 YARDS -- M / pattern 318 (95%)

40 YARDS -- IM / pattern 225 (63%)
40 YARDS -- F / pattern 240 (67%)
40 YARDS -- XF / pattern 259 (73%)

12-Gauge w/ 28" barrels
Winchester AA Extra-Lite Target Load
1 oz #7 ½ lead (344 pellets) @ 1180 fps
30 YARDS -- CYL / pattern 194 (56%)
30 YARDS -- SK / pattern 248 (72%)
30 YARDS -- IC / pattern 288 (84%)

40 YARDS -- LM / pattern 260 (76%)
40 YARDS -- M / pattern 272 (79%)

Obviously, the only way to really know how a gun/choke/load combo will perform is to pattern it! That said, it usually takes a little more choke in the 20-gauge to reach similar 12-gauge pattern density.

Good luck!
