The locking block will deform until the action ceases to function. I quit at round 62. As far as we could tell and measure, thr receiver and bolt did not change dimension. The 89 copies the 71 more than an 86. The locking bolts are slanted in a 71, straight in an 86. The 89 is made of 17-4 which is really tough stuff. The prototypes were made of 4140 which is also tough. I stuck a case one day, called a friend that runs the lab at Western. He guessed the pressure was over 90k to stick a straight wall case. I shot twenty more.......from the shoulder. This was in a 4140 steel prototype using 296/110 and Kelye’s punch bullet. That is not recommended to shoot in your rifle. Reeder may have built a new locking bolt that holds up but take a look at how little engagement there is. Thats all that keeps the bolt out of your face!!! Also measure chamber wall thickness and receiver wall around the barrel. The Marlin will work at lower pressures in 45/70. The 50 Alaskan conversions are scary thin, like I dont want to be around one being shot. The maximum chamber pressure is reached before the bullet exits the case mouth in a straight wall cartridge. This from a ballistic lab so please dont tell me how wrong you think l am. Let that sink in for a moment, these high pressure straight wall cartridges are something!!!! The firing sequence shows ignition then the pressure go almost vertical!!!!! A little flat at the top and down it goes. The bullet is moving but its up and down before its exited the case mouth. Yahoo buckaroo!!!!

I'm wondering if there is potential for a companion rifle for my 500 JRH BFR here??? maybe with 500 S&W cases cut down, as long as the rifle would feed a "special" length case, like most levers would... would guess the JRH cases could have issues with extraction with the slightly smaller rims... anyone with a 500 played or ever tried a JRH cartridge in the gun???

Good question. I was going to ask that one myself.

For a long time, I was wanting an X Frame in 500 S&W, & I had looked at these rifles over the years, several times... when I finally fell out of love with the X Frame, because of the balance, ( I may still end up with one of the shorter barreled X Frames in the future ) but the BFR ended up getting my original 500 money, in the 500 JRH flavor...
since these are pretty much custom rifles, & very few changes would likely be needed, I wonder if a 500 JRH chamber would be possible??? although it would be more versatile chambered in 500 S&W... I'm just not much of a fan of running shorter cartridges in longer chambers, especially so, when they are of such high pressure, that a carbon ring, or chamber erosion might occur, causing problems in chambering the original cartridge the gun is marked for...
if one was to use shortened 500 S&W cases for your BFR, just by nature of use, the Bighorn would have to cycle flawlessly with the JRH length cartridges

I was with you 450ak till you said you would not want to be around a 1895 50ak when it’s fired. I have shot hundreds close to 750 or so rounds out of my 1895. From buffalo bore 525’s to my hand load cast 375 mountain mold, 435 and 525’s. Using Benchmark powder for hunting and trail boss for the range. Maybe I got a unicorn! Ps. Your welcome to come shoot my 50ak anytime!

Thanks fox trapper but ill pass. There isn't enough metal left around the chamber especially on the bottom.

The lack of metal around the chamber was one of my problems with using a 348 cased wildcat in the 1895. I like the Marlin for what it is . A nice light handy little thumper. A 400 gr bullet at around 1500 fps will get A lot of good work done. But trying to turn one into an elephant rifle is imo a mistake.
What bullet weight/velocity can be got realistically from the Big Horn in 460 and 500 S+W ?

Ive only worked on the 500 Smith. Easy to push a 450 grain gas check to 2000 in the 22”. Easy to push a 400 grain Hornady over 2000 in my 18”. Cases (starline) last many firings but need to be trimmed. Kelye’s punch bullet would be fun to shoot enormous animals with. They are very difficult to stop.

And we have shot the 500 grain Hornady at 2000 fps. Thats an interesting bullet and a good one. Mike Mcourey shot two bull giraffes with them. Pretty good test of a bullet. Most of our higher velocity loads are with Lilgun and federal 215 primers. We havnt melted the rifling yet.....

Would be very nice to have a levergun that shoots both. I will confirm with them before I get one but I do not see why it would not work. That rifle will go nice with my snubby 500 S&W.
