View Full Version : 45-70 Marlin loads?

I have had a good Ballard rifled Marlin levergun for several years, but have only fired it once with just so so result.

I have come buy two new molds 1) RCBS 405 GC and 2) Hoch 350 GC (this mold is nothing more than a solid point version of the old Gould mold with a gas check shank added.

I am looking for load suggestions and experiences that might be helpful in developing loads for these molds.

I am not really interested in running these bullets at really high speeds. Somewhere between 1.4 and 1.6K fps should be about right. I have fired some 500 grain bullets out of this rifle at 1.9K fps and want no part of that again. Jeeeze!

I have two moulds in the gould design(360gr-no HP). One I had Mountain Molds make for me with a flat base. The other is a NEI design with a gas check. I have been running these with RL7. I can't remember the load off hand but it was a mid to low range marlin load from the lyman manual(360gr). I was looking for 1700fps. Gets your attention but not brutal. Shot well in my marlin 95s and guide gun. (PS - I don't shoot 45-70s from a bench, rather stand up and roll with it.)

I have a Marlin 1895 with Micro-groove rifling I load 50 gr. of h4895 under Beartooth 400 gr.wfnbb and use a ox-yoke wonderwad to act as a gascheck[seems to work!]It's the only way I could get bevel-base bullets to shoot right.[I was too cheap to spend on gaschecks when I bbought my first box of cast bullets]You learn and adapt!

Chargar,

Try 27- 31 grains of 5744 or 30-34 grains of 4198 with both bullets should get you close.

Howdy Chargar-

I've had very good luck with AA-2495 in the .45-70. 46 grs. gives about 1550fps with the Saeco 405gr RNFP bullet.

I have tried AA-5744 which has left me unimpressed accuracy wise in all my rilfes so far though others apparently have had good luck.

Best regards-

Sky C.

Chargar-

As you know my family has a long history of making fine firearms so I figured I'd give you my latest load.. Heehee :mrgreen:

1895GS Guide Gun Ballard rifling 45-70- RCBS 405gn GC sized to .459- acww- LBT blue soft- WLR primer- OAL 2.585- Lee Factory Crimp.

From 41gr to 48gr of H322- the best groups were 44gr of H322 with an AV velocity of 1645 and the SD was 31. Groups ran about 3/4" center to center at 50yrds. Absolutely no leading.

I meant to use the term better "Standard Deviation" with the 4895, but not better groups, and lower velocity, with simular loads. (had a momentary sectional density re-occuring brainurism)

I got better sectional density with IMR4895 but not better velocity or groups with simular loads.
I dont get it , how does changing powder change your sectional density?

Chargar, try 50 grains of 3031 with your big RCBS boolit. I first used that load with the Lee 405 FP, and have since used it with the RCBS 405. The Lee boolit weighs 415 grains and chronographed 1660 in Winchester brass. I haven't chronographed the same load using the RCBS boolit, which weighs 427 grains, but it feels about the same on my shoulder and is more accurate than the Lee in my Ballard Marlin. It is a pretty stout load, but I keep a sandbag between the rifle and my shoulder when shooting from the bench.

Perhaps Mr.Marlin meant LOAD density,meaning that 4895 filled the case more than 322 which is very likely but I've never used 322 before so I don't know for sure.Shootrj2003

Yep. Sorry bought that.

Disclaimer- use any of my information at an incredible risk... :shock:

I meant "Standard Deviation"... fixed it above.

Sorry bout that, but you sent me into a vertigo spin I have not yet recovered from. I feel kinda lop sided and even though I aim for the door I still run head long into the post,OUCH! Your disclamer is duly noted and proper caution will hence forth be adheared to. I will soon be running a batch of speed green and if you pm an addy will send you a sample slice. It can also be used as a soothing salve for abrasions and embarresment. If a sample slice wont fully heal your wounds a two oz hollow stick is $3.50 or bulk at $30.00 per lb cake.

I have a Marlin 1895 and recently bought a NEI 350gr. mold for it.With wheel weights it drops bullets weighing about 420gr.Friday I took it to the range to try them out .The load was 45gr. of RL-7 with no filler.This load fills the case fairly full and I see no need to use fillers.At 50yds. I put 4 out of 5 shots in a 1in. group.At 100yds. 3 shots were at about 2in.This was with a peep sight.This load should give you about 1600-1700fps.according to the manuals.Good luck,Jeff Taylor.P.S.This load kicks !

With the RCBS 405 grain bullet my favorite load is 28 to 30 grains of 4198 (either) with a Dacron wad of about 2.0 grains. It is a good smokeless duplication of the 70 grain BP load. Any standard primer will do.

That's OK Dan, I don't get many abrasions, but what I need is a brain Doc- and now I just learned we have one of our own... Here!!

Dan-

Do you and the Mrs. Bull Shop still homeschool youngsters?

If so maybe we can make a trade for a stick or 2. Go to:

In addition to the XMP5744 mentioned above, I use 23 to 26gr. of 2400. Very accurate, if a bit dirty. My 1895's have improved greatly with firelapping.

I've Had some nasty/scary experances using AA 2495 with lighter cast boolits with the 45-70 .
such as boolits hitting everywere , the differances between high velocities and low velocities was 250 fps , hangfires , but the worst was i got a boolit lodged in the bore . my conclusion was that 2495 is too slow burning for cast boolits lighter than 400 grs . here is a tip. if there is a lot of unburned powder left after the shot , switch powders .
ive had lots of good results with reloader 7 , reloader 10x , H322 and imr 3031 . reloader 7 worked the best with the lighter cast boolits .

one of these days , i am going to try Imr 4198 under the 315 gr NEI ......one of these days .....
