I was wondering what powder and bullet weights any of you might use for the 45-70 revolvers.Ive been considering one of these but have been wondering about the practiality and recoil of this round,any other chamberings you like,Im not looking for knock you of the stump recoil.

I own a BFR 45-70 and with factory rounds its a pussy cat. With the weight of the gun and the scope its felt recoil is about on par with my 44mag or my 480!

I've shot a buddy's BFR in .45/70 quite extensively, and even loaded hot it's not objectionable in least (at least not to me) from a recoill standpoint. I have also never seen a more accurate revolver. It's crazy. I have rifles that aren't that accurate. It's a bulky piece, but I say go for it!

Id thought about a 454 but I hate that whippy muzzle flip of the few Ive shot,also thought of the 475 linebaugh and loading it down some but components are high priced. Thanks for the advice I sold one of my bows so another hand gun is callin me.

That is my gun Whit shot. I shoot bullets, boolits from 300 to 448 gr and the very best powder is SR4759 for the barrel length. I also use a Fed 155 LP mag primer. If you get it, I have loads for all kinds of bullets. The gun is capable of less then an inch at 100 yards. The hole in the top of this can is 5 shots at 100 yards. The other holes are from a rifle.

Thanks 430man I sure appreciate hearing from you,Im going to order it out on Monday and would sure appreciate some help with load data when I get it,I know they are big and bulky as some have said but posting on a field or funnel in the hills that should be a plus in my mind.

They're not svelte, but they are no more bulky than some of the single shot specialty pistols guys hunt with. You will be happy and surprised by how it shoots.

Great gun without the "whip" of some of the high velocity calibers. I use either the Lyman #457193 or a Montana Bullet Works 405 gr. cast bullets with either AA-2015, or H-322. Lately, I have been experimenting with AA-2200 with good results, and very good accuracy. Because of the volume of powder, I use a F-215 Magnum primer. These loads all generate somewhere in the neighborhood of 1,250 fps, which duplicates the velocity of the U.S. Army loading for the Springfield. If you have read much of John Linebaugh's writings, you will know that he likes heavy bullets at similar velocities in all big bore handguns. In his words, those loads "...will shoot through anything on this continent...". He is correct. Higher velocity in a cast bullet just generates more wasted energy. You did not mention barrel length, but IMHO, the 7.5" is too short. I had one, and replaced it with a 10.5", which I liked better, but for me it was a little too long, so I sent it to Magnaport, and had it cut to 8 3/8", along with the MNP custom treatment. Works very well. That is the gun in my avatar, but it looks a little small on the bears head (19 15/16").

Works very well. That is the gun in my avatar, but it looks a little small on the bears head (19 15/16"). I would be interested in your load work. I load for accuracy but the average velocity of about 1632 fps with hard cast does not work good for deer and boolits need to be softer or they just punch a hole. They work better at very long ranges. I would prefer about 1300 to 1350 fps without losing the accuracy. That might be a stretch with the twist rate and full powder burn in the length. 4759 can not be downloaded much or it will fail to ignite just like H110 and 296. That means a slower powder that takes up more space but it must burn. I tried faster powders like 2400 and Unique with sad results. 4198 gave me pressure excursions and 3031 was half unburned. Since your powders dance on both sides of 3031 it is of interest. The funny thing was Varget, did a good burn with decent accuracy. I am willing to experiment more and maybe the LR mag primer will help the slow powders but the BFR has a 22# to 23# mainspring and a 28# should be used for a LR primer. I use a 26# Wolff variable mainspring so it should fire them better.

Sawfish, that is truly beautiful.
If it were supposed to be easy, they'd have sent my little sister to do it.

I have not had any problems with ignition of the F-215 primer. I have heard of some ignition problems with the CCI LR Magnum primers, but the primer cups are quite a bit harder/thicker in them. Thank you for the nice comments, but the compliments go to Ken Kelly at Magnaport for his impeccable craftsmanship. It really makes a difference in the gun, but if they get too pretty, I don't want to hunt with them.

Anybody ever tried a black powder cartridge in a 45/70 BFR?

if it's a JT frame you can load it to 450 marlin pressures but if there is not a JT prefix on the serial # you shouldn't. I used levergun load listings for the 45-70 and I was running a 440gr Hardcast at 1650fps with a max load of Benchmark. I had the 7.5 in and it was a handfull but accurate. With a 2x Leupy it would shoot close to moa at 100yds.

Just how many 45-70 rifles have you seen that will shoot as good? I, for one, will never part with the huge hunk of steel!

Anybody ever tried a black powder cartridge in a 45/70 BFR? I asked MR about that and they told me "No black powder." I have not figured out the reason since pressures are so low. Maybe you can ask them.

430 man Ill bet that the reason for no black powder is because it burns so dirty and with so much residue that it would gum it up before you got thru 5 rounds.I shot Swiss BP in a 45-70 single shot rifle with excellent results but every 3rd round or so I had to patch it.
