Is there a big swing in ballistics between firing from rifle vertical (up), to firing position, and firing from horizontal, when powder has laid flat? That little amount of powder would lay flat, below the centerline, so the primer flash sets the whole charge off at once. Less forgiving powders would spike the pressures.
I loaded a 10.75x76 with 55gr.s of 3031, but was careful to fill the case with a non-migrating filler.

Back when I was hung up on square bolt Marlin 1895's and 1893's there was a dealer in California I got a rather nice Marlin 1895 in 33 WIN from . He also had a circa 1896 Marlin 1895 that had been rebored most likely in the 30's from 38-56 to 50-100/110 I seriously considered that rifle for awhile but I don't think I ever could have gotten my money back when I tried to sell it . Of course already having molds for the 50-90 Sharps was also a contributing factor .

Montana
 

Just got back this afternoon from the Lewiston area of Montana. Just quick heads up this area got hit hard three times in May and June by heavy hail storms. Sharptail and Huns took a beating in those areas!!!! Pheasant populations seemed to be up!!!

I used to hunt Lewistown but then tv shows and magazine articles came out about it so too many people for me now. I like the town but I am more used to places where you don't see any other hunters for days on end

Great slabs of cow at Harry's Place on the east side of town. Way more than I can eat and my dogs eat well.

Edgar I haven't noticed any difference in performance. The Trail Boss powder takes up more room than you'd expect.

Lewiston
 

Bruce,
I understand about your thoughts on Lewiston as that is how us Arizona Mearn's Quail hunters feel about Sonita and Patagonia. I can't believe the invasion of out-of-states hunters hitting Sonita/Patagonia in January. I hunted that area for 25 years before I ever saw a out of state hunter, oh well I guess it's called progress.

Montana
 

Not to be a 'wise guy' but Lewiston is in Idaho and Lewistown is in Montana. Sorry about the comment, but I used to live in Fergus county and could not help myself. Mark

I fully understand and commiserate with you about more and more hunters invading our favorite areas. When I first started hunting a little section of Vermont's Northeast Kingdom in the late 50's and early 60's we were "outastaters" or "flatlanders" but after hunting there for the last almost sixty years I am considered 'one of the community or fraternity' of local hunters and I truly enjoy and cherish the trust and friendship of those good folks.
I hunted my home state of Massachusetts in my teens but when the pheasant population disappeared I had to find someplace where I could satisfy my lust for bird hunting and deer hunting so I became an "out o' stater". I had no choice - there were no longer any places to hunt in eastern MA and no real game or gamebirds to hunt. I went to Vermont where my Dad and I were invited and welcomed. A lot of folks just need to hunt other states if they want to hunt at all.

Now, more and more people are "invading" our special places in VT too... I can't really blame them.

Lewiston is also in Michigan, and is in good ruffed grouse country

Lots of space in the northern plains but when a place gets on tv and in the magazines , it's not long before it's over run. What discourages me about Lewistown is the bird dog trials they hold on sharptails and huns in the area. Lots of people with 10 to 20 dogs that they run and move all the birds out then many stay for the start of bird season then kill the birds .

You see full dog and horse trailers from Georgia, Tennesee, Kentucky from the big kennel breeders. Maybe they don't have birds left down there.

I've been to too many places that used to hold birds and then find they have been flushed out or shot out. I have two bird dogs and several walking hunters with me. We may have 3 or 4 dogs down at any one time. I can't match controlling 10 dogs by horseback out on a half section field and scouring every bird in the area. That's why I've moved on.

Nothing wrong per se with bird dog trials but when you run them on wild birds then stay to kill every bird you find with full kennels of dogs, that's neither for me, not my kind of hunting , and I don't want to be around it.
