Of those who have shot this little beauty, or perhaps tried different versions, I wonder if any have chronied the slug out of it or tested it for effiency of powder charge? I am curious to see how efficient the short barrel is with 3" and 2 3/4" slugs. That is, is all the powder burning up before the slug exits the barrel?
Thanks,
This doesn't really answer your question, but does offer an interesting looking into the effect of barrel length vs velocity.
Shotgun digest 3rd edition...page 74 "The Long and short of it".
A Marlin model 55 bolt action 12 gauge was progressively tested and cut down, and re tested...from 36" to 12" Approx 464 rounds used. Cylinder bore at 33". (Any number mistakes are mine as I'm typing out of a book).
Also I'm only typing out 3 sample groups listed:
Federal 2-3/4", 00 Buck, Average velocity out of 5 shots, and fps:
36" 1234 (full choke)
33" 1276
30" 1278
27" 1224
24" 1210
21" 1207
18" 1202
15" 1274
12" 1197
Federal rifled slug, 2-3/4" : Average velocity out of 5 shots, and fps:
36" (not tested in full choke)
33" 1558
30" 1554
27" 1531
24" 1457
21" 1309
18" 1428
15" 1327
12" 1227
Winchester AA trap(7 1/2 shot), 2-3/4":Average velocity out of 5 shots, and fps:
36" 1234 (full choke)
33" 1265
30" 1293
27" 1141
24" 1326
21" 1265
18" 1207
15" 1211
12" 1209
I'd personally like to see some modern testing done, with these new shotguns, and the new ammo we have these days.
Also I'd like to know what effect different types of chokes would have on velocity.
