I'm just a ol' country boy...not a physics major, but this is my own experience owning both. When you're on the line and two shooters are shooting...one a .45 and the other a .50, using the same gr. round, same powder capacity you can tell who's shooting the .50....Maybe someone on the board who shoots both can explain (better) the difference between recoil, torque of the .45 vs .50.

Once you get above 70 gr. in BPCR it seems recoil becomes far more problematic for most people. Shooting a 50-90 or a 45-90 in a regular weight, or even the HB, takes it toll on people quickly. Once you get above 14 lbs. in rifle weight things tone down. Of course, the 14 lbs. & 16 lbs. guns cost a lot more and are not really field guns for hunting unless you're Hulk Hogan or have a pygmy gun bearer.

Regardless of the semantics involving physics, a person should shoot one before buying as $2k of buyer's remorse is a tough pill to swallow. :wink:

Does Shiloh offer a 1/32 ROT?
I Think a 32 would let you get a 600 grainer to still fly straight if one wanted to shoot a heavier bullet at times.
I had my .44-90bn with a 100 gr load of 3F and a 510 gr bullet and the .50-90 with a 110 gr load of 2F with a 720 gr bullet and I could tell the difference, :lol: so could my Wife. She made the comment when I got home and she was in the house 1 1/2 miles away across the field and she said I could tell when you switched rifles :lol:

You were run out of here on a rail in the past, Mr. Liberal. Now run along and campaign for Hillary or Bernie, the very people who would take away our gun rights. :roll:

Run out? Think again. You don't know my politics any more than you know about shooting bpc rifles, but trust you to resort to ad hominem attacks of that sort.

Ya Kurt...Don't know what it is, but I can be shooting my .45 2 7/8 all day at the range...nothing new, as soon as I open a few up with the 50 2 1/2 all sorts of people come over to see what the fuss is all about! But the best part is...they are all smiling :D

:D Dennis I like shooting my .50.
I shoot several times a week on out range and there is always a bowling pin hanging at the 200 yard line and I been banned shooting at their pin. I have to hang my own pin :D Those guys are shooting their black plastic .223's and at times a fine M1A or a Grant and the .30 calibers will swing the pin more then the .223. When I line up on one with my rifles that pin will make loops around the pipe it's hanging from and when I shoot the .50 the pin explodes or it gets sent over the berm when the wire or cord it's hanging from breaks :lol:
:cry: no one lets me play when I uncase the .50 :lol:

When I was in the Corps, I was a M2 gunner for a while. All I can say is you get taken care of when you man a .50. Now I know a .50 Sharps isn't the same as a .50 BMG but I get a thrill either way shooting the .50. Smiles all around!

Kurt that's why the 50's in our aircraft in WWII were so much more destuctive than the Brits were with their 303's or the Germans or Japanese 7.62's. But their 20mm's more than made up the difference with the exception of the P-38 with the 20 in the nose. :shock:

Dennis.
When I went through advanced Infantry I qualified with the .50 and the 1919-A-3 .30 caliber. I made the big mistake that day on the LMG range qualifying with the .30 cal. That zig-zag target with all those connected squares on it going every which way, before my belt was shot up they went to score the targets and a E-5 asked the RO how do I score this one? all the squares are shot out. The RO told him count the few outside the squares and subtract then from rounds fired. :?
I carried the 1919-A-3 for more then a year before they gave me the light weight M-60 :D
I think your .50 BMG would be a little hard to fit in my GP bag with out unscrewing the barrel when I jumped out of the C-130' :D

I have a 16 pound 50-90 that I killed a cow elk in one shot with. The next shot out of the barrel killed a mule deer buck. That was 2003 and I haven't shot it since!

You'd think I would stop there but wait there's more!

I've owned and shot several Sharps in 50-70 1 3/4 case. A few 50-80 using the 2 inch case. A couple of 50-90 2 1/2 case. And one 50-140 with the 3 1/4 case. By far I prefer the 1/36 inch twist in a 50 with the 1 3/4 case.

I think the horses mouth at Shiloh mentioned earlier in the thread only answered the specific question you asked. You should call again and ask which twist and case length most people like today based on results and maybe what would they build for themselves in a 50. You should also listen to Orville when he replies later to this post. :wink: :wink:

In my experience anything other than a 1-36 twist in a 50 is a mistake.

Haw, no more Shiloh's. I have 7. I thought about a 77 in the .40-65 or .44-77 but as long as it takes to get one build and at age 76 knocking on the door I would never get the bluing wore shooting it anymore. The bluing is wore off my 22 twist .50 :D
Nothing wrong with a 1/22, 1/24 and the 1/36 for a .50. I have shot all three twists in the .50's including the 3-1/4. I shot the .50-70 and .43's roller's and sharps with the slow twists and light bullets and hit what I wanted to.
When it comes to the Sharps rifle. A person should get what ever his heart desires and not ask on a forum what he should get. It's just like dry wine or sweet wine. Some will tell you dry wine is like drinking septic water and sweet wine gives them headaches :D
I was talked out of getting a .44-77 16 years ago or was it 17 ???? :D well I finally got it after 6 in different calibers and I shoot it the most now.

My main "go to" rifle was my .45-70. I had Steve Rhoades cut and turn the bbl to 26". Just barrel sights and sling. Nothing fancy to shoot, but a great handling rifle for hunting and general shooting. I recently sold it to a buddy of mine and am having a new one built the same way but with single trigger this time. Simplicity at its finest.

"Dry wine or sweet wine" you advise choose and drink, don't ask!! Your advice on this forum is almost always appreciated. Thank you.

My advice is usually too NERDY, too pedantic with too many numbers. I am 70.97 yrs old and have been shooting a Shiloh 50 3-1/4 for more than 40 yrs but still have not learned to give simple, clear and useful advice like you :D It's not likely I can learn by 75 or 76 yrs old :( . Oh well ; I can keep trying.
I hope the .44-77 is all you hoped for
Andy.
