I have been loading shells for a loooong time and allready load 1-1/8oz at 1470 fps and am looking for somthing different, and I shoot a 10ga so am not interested in longer 3'' or 3-1/2'' 12ga,. The load I am going to build is a 2-3/4 Fiocchi hull, Fiocchi 616 primer, 32gr Blue Dot, LBC 50 wad with 2 slits, 1-1/4 oz # 1 steel shot, over shot wad and a roll crimp. this load is for the occasional goose while I am duck hunting, if I am pursuing geese on purpose and I mean real geese ( Honkers ) not stupid snows I use 2 oz of #2 hevi shot in 10ga, reloads of course. I live on fir island, Skagit county, WA so don't give me any grief about snows I kill plenty but prefer to hunt ducks.
Well, I'm not trying to get in your business, but I'd definitely get that one tested for pressure before I fired a whole bunch of 'em. Don't get me wrong, I'm not a big Blue Dot user, so I'm not exactly on top of its spec's, but it seems like you could get more bang for the buck out of a few less grains of Alliant Steel powder. Here's why I say that:
BPI's data suggests a 1 1/8 oz load with LBC 43's using a 2.75" fiocchi hull & primer with 32 grains of blue dot @ 11,000 psi, and it claims a 1,500 fps velocity. Moving to Alliant Steel and using 34 grains in the same recipe drops pressure to 8,800 psi, with a published velocity of 1,475. The same powder charge (32 grains, Blue Dot) using a 3" Fiocchi hull and a 1 1/4 oz load nets 1,425 fps @ 10,600 psi, whereas a 32.5 grain Alliant Steel charge using the same data gets you 1,450 fps @ 8,800 psi.
Adding an eighth of an ounce to the 2.75" Fiocchi/Blue Dot load that is published @ 11,000 psi is definitely going to send you above SAAMI thresholds for 3" guns, and quite possibly for 3.5" guns. Swapping off to a 32.5 grain Alliant Steel charge will probably keep you within safe operating pressures. In any event, using Steel powder for that particular load would dramatically reduce pressures and result in a significant reduction in wear-and-tear on your firearm.
My only other suggestion would be to go with an LBC 43, rather than 50. The 43's will handle a full 1 1/4 oz load at setback, and you wouldn't have to deal with the possibility of having to trim all the wads. Like I said, I'm not tryin' to get in your business, so take that for what its worth.
Smell that? Smells like sumthin died in here.
