Pressure Test for 19gn Red Dot

[William Davis]

Appreciate your posting this. Thinking about replacing my 23 G Green Dot 1 1/8 oz load, same components . It's a little faster, more than it needs to be, and not a real clean burner. Will load up some of the 19/RD 1 1/8 shoot a round of Clay's and see how I like them.

Question for you guys, seems to me Green Dot is better suited for heavier shot loads. Agree ?

I had trouble with Cheddites not chambering in both of my 10's after a couple reloadings. Even after super sizing. It was a rim diameter issue as well. So far Remingtons are working ok. Different lots than your Cheddites I guess?? Or maybe just my guns?

Regardless of the difference in pressure of these three loads, none of them will damage a well preserved ten gauge. A switch to Green Dot or Unique will lower the pressure, but maybe at the expense of poor cold weather performance. Thanks for sharing this information, Craig.

Thanks very much for sharing this data, Craig. I gave up reloading years ago when I became a wealthy government retiree, and a friend of mine opened his own ammo factory. I don't own or shoot a 10 gauge, but both my brothers are fanatics about them. I know they'll be interested in these figures.

Well if I get an invite to a decent Dove field for the opener I just may carry a 10 with Red Dot 1 1/8 ounce loads of #8 . As well as a 20 gauge VHE . Well that is after I shoot a round of skeet and see how they do in my EH #2 frame .

CL. how are your crimps with this wad column? How deep are you seating the SP10 wad? I found that using a 16 ga. lubed 1/2 inch fiber filler with a .125 nitro card in the wad cup gives me perfect crimps with no dishing. Without the .125 card I found I had dished crimp with some open centers. I am asking only because your .375 filler is quite a bit shorter than my fiber/nitro card filler combination. I had my 1881 Greener out today on the clays course using both Cheddite and Federal hulls and crushed the clays. No large chips and most were vaporized. The 19 grains of Red Dot with an ounce and a eighth of 7.5 shot works very well. Works nicely with all three hulls. Both my Greener and George T. Abbey(probably a Scott made gun) have laminated steel barrels and the tested pressure ranges are comfortable in these heavy barrels. Neither guns are tightly choked or overly heavy at under 9 pounds. I think of them as over bored heavy 12's. Great guns and great loads.

Eric: I think the crimps on my loads look good with no open centers, no wad pressure on the sp-10. I had to add card wads to the red dot load versus 7625 since RD takes up much less room. Craig

good looking crimps...charlie

Those are fine crimps. I too use no wad pressure. I suspect it's just the difference in the way our loaders are adjusted. Mine is a MEC Sizemaster. I use Red Dot and SR 7625 for the once and an eighth and SR 4756 for once and a quarter. I have a very good supply of both of the SR powders. Must take down the 16 ga. machine and set up the 10 soon as I have worked my way to a pile of empty hulls. 10 ga. hammer guns are way too much fun!!

Eric FWIW I do about the same as you with the Federal hull and 19gr of Red Dot. I use a 1/2" 16ga fiber filler wad and a piece of a cheerio to achieve a proper folded crimp using the SP-10 wad. I am not sure how Craig is getting a good crimp with a much shorter filler wad column but obviously he is. Here are three random Federal's loaded with 19gr of RD for the soon to start crow season. Thanks again Craig for sharing this information with us.
