An acquaintance of mine up in Wyoming once told me that he likes to dink around his place carrying a 3.5” 500 Linebaugh Bisley, loaded with some some pretty heavy bullets (440’s I think) traveling around 1000fps. He said recoil isn’t all that bad due to short dwell time and maybe not all of the powder getting burned. My question is: what is the heaviest bullet one can launch from a 3.5” 500 Linebaugh traveling an honest 1000 fps? Thanks
Matt

Since I have a 500 Linebaugh coming I am very interested in an answer. I dont know so I am looking for someone smarter than me.

I do not have a 500 Linebaugh, and may never own one, but I have 3.75” SS Bisley 44m that I might have converted to either 500 Linebaugh or 500 S&W Special at some point (not at the top of my bucket list, but I’m gathering info while I’m thinking about it). A 3.5” barrel is really too short for my taste, but I’m considering it. A five inch barrel is really much more to my liking. |

I dont have one yet, but I am on Ronnie Wells' list. I hope maybe by Christmas. If not, no big deal. I know these things take time. I only shipped him the donor revolver this week. I was going to go with a flat 6 inch from cylinder. I am looking forward to throwing those big chunks of lead.

That depends on the gun and who made it. Different makers guns can stand different pressure.
From most reputable makers 1000fps and 450grs is safely attainable.

The powder burns, it always burns.
Might get the 525gr to 1000fps in that short barrel. It won't be gentle doing it.

My question is: what is the heaviest bullet one can launch from a 3.5” 500 Linebaugh traveling an honest 1000 fps? Thanks Matt I don't believe a short barrel cuts recoil meaningfully through reduced dwell time. I just haven't experienced that with snubnosed revolvers. Unburned powder makes fireballs that add to perceived recoil. Less barrel is less weight, which is always more recoil. I don't know everything, and I admit that I haven't tried big bore snubbies. But I don't think short barrels explain recoil reduction. I think this Wyoming acquaintance may have been using lighter or slower bullets, or be a much tougher guy than me. Possibly all three. Don't get me wrong here, a "lighter" 400 grain bullet going "slow" as a 45 Auto is a hell of a thing to get hit by! I have really enjoyed loading 500 Linebaugh with 420 grain bullets at 768 fps (7.5" barrel). Same thump as a 240 grains 44 Magnum blazing along at 1,344 feet per second, but without any fireball and much less muzzle blast. Actually since there's less powder needed, it should have even less recoil. Every grain of powder kicks coming out the front, burned or not. And usually a grain of powder kicks more than a grain of bullet. Really big slow bullets are almost like cheating physics when it comes to recoil. The catch is the very curved "rainbow" trajectory. But if you can manage that they really aren't too bad. I second a 525 grain slug probably being about the heaviest thing that can be driven to 1,000 feet per second in a short barrel. And it may depend on the gun. One word of caution though — it will kick! I've shot 525 grain slugs up to 988 feet per second (7.5" barrel), and while it's not the heaviest kicking load for the gun, it's a lot! I stopped at the START loads. I just didn't see anything else to be gained by going faster. |

Looking at Quickload and setting the max pressure at 30k, a near full case of H110 should be able to hit 1000fps with a 525 and a 3.5" barrel, modeled at 5" fwiw.

My version of Quickload doesn't have A11FS in it. Does anyone know if more recent versions do?

I haven't used #11fs yet in the Linebaugh. I'm waiting to hear back from them on the burn profile to enter it into the GRT program I use to get starting load data.
It's great in the 357 snub for reducing muzzle flash over #9.

Out of my 4” a 450gr. makes 975-1000fps with HS6. And it is a nice easy shooting load,

I believe Kelly Brost, who was the former owner of Cast Performance, shot 525's at 1000 from his 4" guns. It is highly likely that it is attainable in a 3.5" tube as well. However, as noted above, recoil is brisk.
I have shot 468's at 750-1000 in 4" barrels. All loads were very controllable both in the Bisley and in the Redhawk.

I left my laptop at work. I'll run Universal and Titegroup profiles tomorrow.
