Patterning Rem 1100 12ga 18.5" Cyl Bore (Cut)

[roo_ster]

For the THR-ers in limbo who have yet to visit TFL:

Howdy:

I finally got around to putting my Remington 1100 together after buying a Scattergun Technologies +2 mag extender and cylinder bore (cut) 18.5" bbl.

The 1100 was bought used in the 1980s and busted a lot of clays back then.

The bbl was originally a 28" fixed modified choke with no rib and a light weight profile relative to most screw-in-choke bbls.  Back when I shot skeet a lot, I preferred this sort of light bbl to anything with a rib or heavier contour plain bbl.

The ST mag extender was bought back before Wilson Combat bought them up.

The whole rig is a bit of a kluge, what with the original high-gloss polyurethane finish on the stock, the polished blue original metal, and the deep park job on the mag extender.

I shot four flavors of buckshot at 7 & 15 yds and on flavor of slugs at 25yds.

7 Yard Performance

(I was running out of time and omitted Winchester 00B Low Recoil WL1200)

Low-recoil Rem 00B was the best performer at 7 yards.


15 Yard Performance

Rem 000B was the best performer at 15 yards and would be my choice for this gun/bbl/choke for HD. The longest shot in my house is ~10 yards. The 000B seems more consistent than the Rem Low Recoil 00B, which does well at 7 yards but goes wonky at 15 yards.

25 Yard Performance

Winchester   X12RS15    12    slug        1          1       1600       25         1.75         2 rnd grp


irst shot was #1 (high left). It was shot offhand.

Next two shots (#3 & #4) POI were 4" high and 1" to left of POA and were shot from a hasty rest.

I was getting sore, as this were the absolute last shots after a box of birdshot and a bunch of buckshot. 1600fps slugs kick a mite.

The last two were shot sort of indifferently. Next time I group slugs, I will have to use a slip-on recoil pad.

===========


I was somewhat worried about reliability and replaced the O-ring before firing. Most shorter Rem 1100s are in the 20"-21" range and I have read about reliability issues with shorter bbls, especially with cut-offs originally of greater length.

I needn't have worried. It ate everything I fed it: Wally-World Value-pack Winchester birdshot, standard & low-recoil buck, and slugs.

It also handled well. Maybe not as well as my preferred plain 26" bbl without the mag ext I used for skeet & bird hunting, but light years better than any of the pistol-gripped shotguns I have fired.

The low-recoil buck was not that much less recoil, IME. The standard recoil slugs sure were thumpers, though.

All in all, if I had a way to store it loaded in a secure manner, it would be my primary HD weapon stoked with Rem 000B and slugs on a butt cuff. But, my two toddlers preclude that and I must be content with a 1911 in a quick-access safe until they are old enough to be reliably safe around loaded weapons not on my person / under my direct control.

You forgot pictures of the gun itself.

I've found that Federal Vitalshock buckshot tends to group better in my gun than Remington buckshot.  I was getting tighter groups at 25 yards with Federal than I was getting with the Remington at 15 yards. 

Supposedly, the reduced recoil Vitalshock tends to do even better, though I haven't tried it.
