I see measurements here for the BFR and Ruger 500 jrh cylinders. How about Freedom Arms? Would this boolit work in the FA 500jrh? Seating depth to not bulge case and also having proper nose length?

Seating depth to not bulge case You have the gun, you tell us what it needs please (seating depth and bullet diameter used). and also having proper nose length? A measurement from a seated case head to the front of the cylinder. Case lengths vary somewhat, what's yours? |

I have started casting for my buddies FA 500jrh. I'll have him measure his gun and post it here. I know that the Lee 440gr is a little too long. Thanks.

Seen this before, can't recommend more than 2 crimp grooves boys... Just my 2 cents.... AND, somebody needs to take ownership over this design and work with Bob on what the majority wants. And I strongly recommend you listen to his council. Because if you DO NOT, he will draw for you what you ask him for and then when it doesn't come out right he will rightly point out that you did ask for it that way. Just saying, he has drawn us countless successful designs. One bullet can't be everything to one caliber. For example in the 32's, we have at least 3 640 designs as we are working on a couple more and THEY ALL SELL OUT ON EVERY BUY! So, you might want to do a 450, and a 420 and a 400 here. But don't try to make it a do all. We have been down that road before. Let me know when you guys are ready and we will get a buy list going.

This sounds very wise. I'd be interested in as heavy as practical/doable for 500jrh in the FA. Seen this before, can't recommend more than 2 crimp grooves boys... Just my 2 cents....

be careful what your intended purpose is. Al Anderson and I shot a couple 1000lb cow buffalo with cast 410 grain hps in our 500 linebaughs and had some pretty dismal results. Granted it had a big hp cavity but on a big animal like that we only got about 8-9 inches of penetration. In my opinion if your stepping up to animals that weight more then 500lbs a hp doesn't have a place. A good old lfn is a much better performing bullets. If I was going to do a hp in .50 cal id step up to a much heavier bullet then a 420 that might still give good penetration. A 50 cal bullet already has a big metplat. Make that expanding and you have yourself a parachute. My opinion might not count for much but fermin, give Al a call. I know you respect his and hes going to tell you the same thing.

following along... I might be persuaded into a group buy... right now all I have is a 50 A.E. but another fifty is in my future  |

I still need that seating depth that doesn't bulge the case (bullet diameter used also). Lloyd go search this site for a Buffalo kill with the 477640 using the large HP. You didn't do it right. |

Lloyd!! How are you old friend??? Guys, this is one of my very favorite folks in the sixgun community. Glad to have you here here buddy and I sure hope you stick around some. I’m going to send you a PM as I lost all your contact information in a iPhone crash. We have learned a bit about cast bullets over the years. These are Cramer style molds and can be cast as Solids, cup points or medium or large HPs. With this design, even in the large HP configuration the HP “petals” exhaust themselves leaving the generous shank to provide more than enough penetration on Bison. As good as the LFN style was and served us for years, this design is better and far more versatile. It is not all just about bullet design however because in addition we better understand how to properly alloy our cast bullet for its intended purpose. Sometimes making change is like pulling nails with your teeth. It doesn’t have to be that way. Here’s that link, you might search Zues and Sixshots posts, they have had great success with this design: singleactions.proboards.com/thread/9086/bison-long-post-warning |

Here is a quote from Dick Sixshot Thompson from the linked thread speaking to cast hollow points on large animals:
Sorry I haven't responded sooner, I've been out of commision for a couple of days. Glenn thats a very nice write up & I'm glad you finally got it done, I know you've wanted a bison for quite a while, great job.
When I first heard that your loads were clocking 1167 fps I was a little concerned because those 70/30 slugs are normally for 1000-1100 fps, if I had known earlier I would have made yours 80/20 WW & lead. Anyway, when you make a one shot kill on a mature bull bison with a revolver that pretty much seals the deal on whether it works or not.
With hollowpoint bullets there are 3 things that you can change, first is bullet alloy depending on velocity, second is velocity itself, & third is, all HP's aren't created equal, you can use the smaller pins to delay expansion a bit, or use the same alloy & go with a solid, thats the beauty of cast slugs, you can take them anywhere you want & they will work, you just have to experiment. High velocity isn't needed with big bullets.
With that big nose cavity they are actually working much like the softnose slugs that I like so well, you get initial expansion & then great penetration.
That was some great shooting with outstanding results, one shot kills are bison are rare with gun.
Dick

It appears the 440gr Leadhead boolits are fine the FA 500jrh. Here are some measurements taken by Paul105 and posted in another thread... singleactions.proboards.com/post/149951/thread"I just went downstairs and measured some Leadheads 440gr 50 cal WFNGCs. Leadheads over all length of 440gr WFNGC .904" with a nose to crimp of .384" LEADHEADS -- Bullet in case .520" (.904 total length minus .384 nose to crimp)" Perhaps we can verify this with Paul105. |

What I was looking for when I asked for a 640 style 50 cal bullet was something that mimicked the 477640 hp. I love the 477640 bullet and thought it would be great in a 50 cal version cast soft and pushed at lower speeds to make for more comfortable shooting in these lighter 50s like the 500 jrh and 500 we. The 477640 is a proven design on large and small game, just need a similar 50 cal.
