Still looking for the right loads, I got to shoot some more paper today with an
Ageis 14” barreled cylinder bore Mossberg 590 Class III 12 gauge at 10 yards.
There’s nothing exotic here, but some of you might be interested the results.

I tried for five shots each of six different loads. I’ll report the ammunition
followed by the the group size, center to center of the two most distant
pellets. Didn’t notice anything odd like huge vacant centers this time.

Where less than five pattern sizes are given, some of the pellets escaped
the paper. Oops. Measurements in inches.

PMC 00 buck, 9 pellets average

9, 8.9, 8, 9, 10.5: 9.1

Winchester Ranger 00 buck, 8 pellets, reduced recoil

6.4, 5.4, 6.2, 8, 6.7: 6.5

Sellier & Bellot 00 buck, 9 pellets

10.25, 10*, 8.2, 11.2, 8: 9.5

Spartan 00 buck, 9 pellets

8.7, 8.5, 8.7, 9.2, 7.75: 8.6

Herter’s Mini Buck 00, six pellets

8.2 9.2 8 8.75 9.5: 8.7

Herter’s Buck ‘n Ball #1 buck 6 pellets and one .650 round ball

5.25, 8.75, 6.5, 7.25, **: 7

*Lost one pellet, made a judgment call

**Shot two shells at the same target, could not
define either pattern

I kind of like the Herter’s Buck ‘n Ball, consider the six #1 pellets
add insult to the round ball injury. With sights or laser I expect
I could get a decent group of .650 holes at 10 yards. I could
not notice any reduction in recoil for that load or for the
Winchester 8 00 “reduced recoil” shell.

Still more 14" 12 gauge buckshot from 10 yards.

Mossberg Shockwave equivalent, cheap buckshot

Spartan 00, 9 pellets average
7.5, 8.5, 10.75, 8.25, 7: 8.4 inches

S&B 00, 9 pellets
8, 14.25, 8.5, 8.75, *: 10 inches

S&B 00, 12 pellets
9, 7.5, 7, 8, 8: 8 inches

Winchester Ranger 00, 8 pellets
7, 5.25, 6.75, 6, 6.75: 6.35 inches

* Wind blew down target, no chance to re-shoot

All pellets caught on paper. Recoil from 12 pellet S&B load
was significantly greater than recoil from the other loads.
Could not detect any reduction in recoil from the 8 pellet
Winchester "Reduced Recoil" load. The 12 pellet S&B shell
jabbed my forefinger of my off hand unpleasantly with the
two screws holding the front strap on my fore end without
breaking the skin.

By comparing these limited patterns with those previously
shot with a similar but different 12 gauge,
although each firearm gives slightly different results, I was
surprised to see how close the patterns from one gun were to the
patterns from the other with matching ammunition!

I have more testing to do, and plan some 10 yard groups with
solids. I'll report then.

Barth, I totally agree with the FliteControl advantage, and have found the same result you have.

This experimental run with cheap buckshot is for me and a family member to get the
best stuff for us. We've both got Class III 12 gauges made from Mossberg 590s. I've also got a Shockwave equivalent I put together before the commercial product came out. My Class III came threaded for interchangeable chokes, so I'll need to wring it out later on. Right now I'm looking for a 33 foot load for in-home use. I tolerate more recoil and prefer a relatively tighter pattern than my family member, so I'm shooting his gun with stuff he might like to stock and practice with while looking for my own solutions.

We both plan to add the green laser/flashlight to our 12 gauge 14" firearms. I'll be using the "shinny sticker" and laser to shoot slug groups in the near future, although maybe it'll be laser and FliteControl buckshot, in which instance I prefer #1 buck.
Actually, sounds like both might be fun.

Right now he's looking at Winchester 00 8 pellet reduced recoil Ranger for home use. I don't think he ever plans to take his gun outside except for practice.
