After seeing Nitro450exp's Lanber O/U 12 gauge rifle I had to have one. So the first range testing with the Lyman 525 (510gr) shows some promise. The two groups are vertical and 6 1/2 inch spread. I'm looking for some insight as to bring the two groups together. I was shooting at 25 yards and using no rest, offhand. My load is 25 grains Herco, a Winchester 12AA wad, Remington Gun Club case, Federal 209 primers. And the Lyman 12 gauge sabot slug. I want bring the two groups together at 50 yards. This will be just right for Michigan hunting. |

25 gr. of Herco is a light load. Muck depends ont eh case, of course, and the wad column. With the Lyman 525gr. (sabot that fits 12 bore plastic shot wads) The slugs I have, are actually 14 bore, ie: .69" and cast from what appears to be WW alloy- at 506gr. I purchased Lyman's new shotshell loading book, just for the slug and round ball loads, but have not experimented much as of yet. Plans ensue. In Fed Gold Medal hulls w/ Win.209 and WAA12F114 wad - folded crimp - 32.0gr. herco - 1,390fps. Increasing the speed might bring your barrels together- or not but unless you experiment you'll never know how YOUR gun behaves. As 12's go, Herco is fairly slow. I started too low for my wads and hulls and got hangfires and blupers. I was using Fed hulls WAA12R(RED) and CCI 209 primers with 28gr. Depends a LOT on the hull. With Rem Prem STS plastics, a WAA12R + W209 - and the 525gr., they used only 25.0gr. and got only 1,249fps at11,300PSI. Rem plastic cases with 1/4" plastic base wad, W209 + one BPGS + 1/2" fiber + three .125" cards under the slug and roll crimped with 36.0gr. Herco, they got 1,533fpas at 9,400 PSI. Same hull, Rem 209P - WAA12F114 + 525gr. slug, folded crimp and 33.5gr. Herco for 1,426fps at 10,200 PSI. When playing with shotshell loads, one must be careful. There are also a bunch of AA STEEL loads in the new 5th edition manual. |

In the morning I'll pick up the Lyman book. I want to stay with the Remington Gun Club shell since I have several thousand on hand. It is the only shell I keep when picking or sorting shells. |

It's good to stay with what is readily available. Note that different wad systems allow for differing crimps. I was able, in my loading for 12 bore double, long ago, to use card and the base cup wads cut from AA12White trap wads. The base cups made a perfect cradle to hold my round balls centered in the bore. I adjusted the card and fiber wads to fit. If at all interested in round ball loads, I placed a cut-ff base cup, cup down against the powder, then fiber wad, then another cup, cup-up to hold the ball. I then fold crimped my cases. I adjusted the powder charge for a 1,500fps load with the almost 500gr. ball. I was able to shoot groups well under 10" at 100 meters with this load - and 12" offhand. I did mount a 2 1/2X to 8x scope for load development. This made hitting at 100yards quite easy. One of the locals needed the gun more than I did, so he gets his moose every year with it. |

Over the weekend I picked up some once fired Rio hulls. Now it's off to the shop for wads and powder. |

In my experience with SXS Paradox guns, increasing the load will move the groups apart, and a decrease will make them come together. I think it has to do with recoil movement, and realize this is opposite to what we expect with a double rifle. I have used Unique, around 22.5 gr. with success. Can't speak to the charge of Herco. This loading at the advise of Ross S. with a 750 gr Fosbery bullet and hard waxed wads. We are talking about small powder charge changes to move the groups here- sometimes a 1/2 gr change will give noticeable group movement. I have no experience with O/U guns, but Graham Wright says the basic principles apply. Enjoy! Doug |

I have picked up some 800X and Blue Dot, I want to try different powders and case's thinking I can bring both barrels shooting to the same point at 50 yards. |
