my 500 linebaugh quest has come to a complete stop in the road. to remind you, it will be a tc encore with a 23" barrel and it will take a 450gr lfn about 1200-1400fps that will kill a deer/black bear out to 100-125 yards. i may try a 500-530gr cast boolit, just for giggles, but it is far off.
the rifle twist is what stops me. will it be either a....
1 in 28" twist that MGM barrels or a 1 in 18" twist that bullberry barrels make?
i'm not a rifle twist guy, i just shoot them. when people start going the greenhill twist........i find something better to do. i'm a big fan of MGM, they do excellent work. i have not tried a bullberry barrel but i suspect they do the same.
so will it be either the MGM or the bullberry? or am i worried about nothing?

A 450 at 13-15? What load do you reckon will get you there, and what pressure are you expecting?

i'm going to use either 2400(24-25gr) or blue dot(19-20gr). what i am guessing it will be around 1200-1400fps.

The Winchester 50 caliber 1886 twist was 1 in 54. Worked well with 450 grain bullets on down in weight. Your 500 grain slugs may take a bit faster twist than that.

I reckon 24-25 of 2400 under a 450 will get you about 1150-1200 out of a revolver at the top end. In a conversation with JL, he called that load "about max" in revolver. You might get a few more FPS out of your 24", but that's pushing pretty hard and I can't imagine a TC is much stronger than a NMB (?). |

i am going to try 2400 starting with a 21gr charge ending with a 25gr charge. it should end up like 1500+/-fps. i know that a tc encore can do 60000-65000psi while a ruger sbh goes roughly 35000psi?(i'm guessing).

You can't go 65KSI in the Encore with a .500 Linebaugh. You are .040 less meat under the scope mounting screws.
Case head thrust on a .300 win mag at 64 KSI is about is 14K lbs. You will equal that same case head thrust on the .500 L at 48 KSI.
If you want more .510 performance in your Encore than you an get with published .500L loads, please look at the .50 AK.

I used to shoot 465's at 1300-1350 form a 6" barrel, though that wasn't with 2400. I don't doubt you could gain a bit more with a longer barrel. 23" might be more than you need though.

If you want more .510 performance in your Encore than you an get with published .500L loads, please look at the .50 AK. i'm sorry about the tc encore pressure, i was just explaining the pressure differece between the encore and sbh. i should have told everyone i am disabled(stroke) and my right arm/leg don't work. everything will be a tc encore that is a rifle. i don't except much more than 35,000psi. the 500 L will be mostly for deer/black bear and it should be 100-125 yards. i'm trying to find what load will work at 1200-1400fps. i know that a 500 L using 450gr cast will do roughly 1300fps(lilgun) from a revolver. from a rifle, i don't know. i am going to 2400 before i go one to something else(blue dot). i know the 500 L and a 23" barrel is not the best thing. but i have found that my tc encore feels right with 444 marlin(23" MGM barrel). i was going use a 25" barrel but 23" is more than enough.  |

I guess the only point I would try to make is that a 450 grain cast bullet from the 500L at 1300, or 1200, or 1100 FPS is easily capable of punching a hole clean through anything that walks North America. No need at all to try to red-line it, no matter the platform you choose.

i thought about the 50 alaskan but .510" boolits you don't need the velocity it produces. i was thinking, if a 450ish gr boolit can do a hole at 1200-1300fps, i shouldn't worry so much about it.
i do like the 500 L, it seems like it can do a bunch more with less pressure and that means less recoil.
