50-90 sharps from a tc encore 27" MGM barrel

Post by todddoyka » Thu Sep 01, 2016 7:07 pm

i'm thinking of getting a 50-90 sharps in my tc encore with a 27" MGM barrel. since this will be my first black powder cartridge, i' will have a bunch of questions!

the first question is what kind of sights do i put on the MGM barrel? it will be a factory heavy barrel(.810" at the muzzle, .850" at the action). i only want to go about 150-200 yards for deer and informal target practice(200+ yards). i prefer a peep sight and a front blade sight but i don't know which does what?

i have found a rear peep sight, but i'm not sure...

not knowing your bullet, load, or velocity, you might require approx 15 moa comeup from 100 to 200 yds.
for a 36" sight radius, 1 moa is 0.010" on the back sight.
15 moa is 15 x 0.010 = 0.15" requirement in adjustability.
you will probably have about a 28" sight radius or even 27".
so your adjustment would be (28 /36) x 0.15 = approx. 0.12".
that sight looks like it might have that much adjustment, so would be useable as long as the 100 yd zero is at a fairly low setting.
a blade foresight is quite good for hunting, and reasonable for casual target shooting.
some prefer a copper coloured blade on dark coloured animals but matte black suits most target shooting better .
a copper one can be blackened with a cigarette lighter and cleaned later, offering versatility.to get a low rear sight setting at 100 yds, a blade has the advantage over a bead that you can file it down if necessary.
I have used similar rear sights on a win 94 and a marlin 95. for hunting it can be advantageous to remove the insert.
that rifle might give it to you a bit, but should be a good killer.
with the available case capacity, you could reduce recoil a little while being more reliable shooting dirty with using a grease wad to reduce powder space.
keep safe,

sorry about that. i think i want to go with a 450gr boolit(lyman 515141) either pure lead or 40:1. i'm thinking of 1000-1150fps using goex fg. it probably will be zeroed at 100 yards and 150 yards will be it for deer. anything over 150 yards will be a informal(meaning rocks, soda bottles and the occasional groundhog!) practice. i won't be using it for a 1000 yard shoot, or even 500 yards.

I was not talking 1000 yds, only 100 to 200 yds.
the setup should be good for that.
if you were shooting 1000 yds you would need up to 1.5" comeup and that sight comes nowhere near that.
your bullet wt is good for what you want, and that gives you a guide to twist requirement.
baco and brooks will supply you a way better bullet mould than lyman.
make its diameter such that it slides neatly into a fired case for best accuracy.
you might find 20/1 or 30/1 to be superior alloys.
pure lead will expand too violently and have insufficient penetration on bigger game.
how I know this is that I was attacked by a feral pig hit well with a pure lead bullet, and was lucky someone else was there to stop it.
keep safe,
bruce.

With that short light barrel you might ask yourself how much recoil you can stand and control that light rifle in the .50-90 caliber. Even with that light weight bullet you listed you will drive this bullet with a load of black powder past 1340 fps and the recoil will be substantial.

kurt,
hence the potential use of greasewads to reduce powder capacity and with it recoil.
one thing is for sure, not many people know more about using the big 50 than you.
keep safe,

Bruce,
I shoot some pretty heavy bullets and full loads I my rifle, but it weighs close to 13# but it still knock your hat off if you don't control it right.
A thin 27" .850-810" barrel on a TC action I doubt that it would weigh 9 lbs especially with a .50 caliber hole. It surprises me that they would even use a barrel that thin walled for a .50-90 Sharps cartridge.
