I just ordered the new Marlin 1995sbl, and have bee doing some research.Has anyone been able to safely duplicate buffalo bore performance? The're claiming 2350fps, 3678ft.lbs. out of a lever action with a 300gr jacketed hollow point.
Any idea what these guys are doing?

Probably something you can not do at home. I can get only 2100 from a 300 grainer out of a 22 inch barrel.

58 to 59 gr IMR4198

62 to 63 gr H4198

i guess id say that why? you now have a gun that will easily devour 400 gr + boolits. these will grind thru most things with a fps rate that is to be seen to be believed.

my 45/70 will out penetrate my 338 on straight grain wood. the load is stout but the preassure is good and the rifle will print 1.5 inch all day long and tho this will not make a boltgun shooter wet their pants,,,it WILL bring home the bacon or moose ect...

anytime i can shoot 400 + gr boolits at 1700 + fps im a happy boy and the knowledge that this {in range] will take on anything i will run into is super.

good shooting and write more...this will be a fun and entertaining gun

Just my $.02,
Why do you feel the need to hot rod your lever gun. I've one of the early ported guide guns in 45-70. I load 53 grains of IMR 3031 and a 400 gr speer. It kills shit DRT. Three bullets touching at 100yds. You can eat the meat right up to the bullet hole.
If you want to hot rod, get a 257 weatherby, a 7.82 warbird or something else. Enjoy the 45-70 for what it is.
If you have to hot rod it, I would recommend you get at ruger #1 or a highwall.

Geedubya is dead right. You don't have to hotrod the 45-70. My Cowboy Marlin 45-70 kills shit DRT too, and I have loaded mine DOWN to where it is really pleasant to shoot. Try a cast 420 grain Lyman 457193 flatnosed bullet over 38 grains of 3031 for 1345 fps. It blows all the way through elk and simply destroys deer and hogs.

60 grains H4198 and a 300 grainer for over 2400 fps.

Check out http://www.brockmansrifles.com & www.garrettcartridges.com I had a 45-70 remington rolling block with a navy arms octagon barrel, it was a converted 11 mm egyption.I had a unertyl target scope installed on it for schuetzen matches and one day a member gave me a couple of 500gr lead bullets to try out in the 45-70,big mistake on my part,I breech seated the bullet then inserted brass loaded with sr4759 with a dacron over powder wad put the curved buttplate to my shoulder and fired it wasn't a comfortable load as it bruised my shoulder which went thru several color phases.That was the only time I ever used that bullet.My advice is experiment with loads that are comfortable to fire and are accurate enough to drop an elk,deer,pig,etc .

You want recoil fun?
All you have to do is get yourself a Hodgdon Annual Manual or go to their website for loading data that will give you all the recoil enjoyment you can stand..
If you must use jacketed bullets may I suggest that you use Hornady's 350grs. They are a tougher bullet, at least the old RN ones I have are..

Absolutely, Low Wall, the 350gr. Hornady's were a very good bullet.

Another good one for elk and moose is the 405gr. Reminton, less than max in the Marlin, keeping them between 1,800fps and 1,700fps.

The 350gr. Hornady's work exceptionally well in the 2,000fps range and up to 2,200fps range on Moose.

With a max pressure limit of 43,500PSI, the Marlins easily make these speeds and up to 2,100fps with 400's.

My buddies Stainless 18 1/2" Guide Gun likes 400gr. Barnes FN's with 49.0gr. Re #7 for 2,007fps. That load is listed in Speer's book with Speer's bullet at 28,000PSI at less than 1,850fps. There are no pressure signs of any sort with the load using Barnes 400's, it's fairly easy to shoot and works splendidly on Deer, Moose and large black bears.

I have a friend with a Marlin 1895 in 45/70. Somehow it won't feed Speer 400 gr. SP bullets. Evidently the action is not long enough, although I've compared the 400 gr. and 350 gr. Speer bullets and the cannalure seems to sit both bullets at the same OAL.

45/70 Govt. works on the same physics as a slow moving freight-train. Big and heavy, it need not move fast to deliver serious damage to whatever it hits. Preferred caliber locally for thick woods and large game.

Marlin 1895CB, 26" bbl. .45/70

525 grain HCGC Beartooth Piledriver, 0.375 meplat, OAL 2.555"

Remington case, 42.0 grains of H-335, CCI 250 primer

Average velocity 1,515 ft/sec. No signs of excessive pressure. Recoil is not bad in a light gun like the Marlin. Feeds well.

If you can't anchor it with this load, you need a big nitro express double rifle.

Just for accuracy try 51.5 grs. 3031 with the 405 Rem. This was an accuracy load given to me by a couple of guys at my range. Fired many sub inch groups before removeing the scope. Many sub 3/4" groups as well.

Several of you guys are right on the money with your loads. I shoot two loads through my NEF single shot with Sub Moa. I use starline brass,cci br2 primers. reloader 7, and 300 gr sierra hp's. The same load again using 400 gr Speer fp's. Both use 50gr rx7.The 300 can go up to 55 gr. and is safe in my rifle. Use caution and common sense when working up your own loads. The 300's shoot flatter and are deadly. But for eastern whitetails I love the 400's. Like the man said It's like hitting them with a freight train.

I shoot a 22 inch barreled Marlin 1895.

300 grain HP at 2150fps have proved deadly on medium game and shoot about 2.5MOA with a Williams peep on the back.

I've shot larger game with both the 350 Hornady RN at about 2000 fps and the 400 Speer at about 1900fps.

Not sure I can tell the difference, they both kill well and even on the medium game, which mainly comprise of pigs and goats here in Australia, the heavy bullets seem to drop things right there.

You can easily get by with either the 350 grainer or the 400 grainer for everything, saves on resighting and other messing about.

Good luck with the 45/70, it's a grand old cartridge that just seems to work.

I have two loads for my 1895 Marlin Cowboy 26" barrel. The first one is a 350 grain Laser Cast with Varget for around a chronographed 1400 fps. That is a load that is fun to shoot and very mild recoil. The second was is a 405 grain Laser Cast with H322 for a velocity of 1925 fps. That is brutal recoil and not fun to shoot but will kill anything in North America and a lot of stuff elsewhere.

I recommend the first load!!!!!
