I am looking for some reloading data for 45/70 with Remington 405 grain JSP bullets. For plinking I had good success with 16 grain Unique but I could not find any data for heavier loads somewhere...

Get ahold of the IMR Guide or look for their data at imr.com. All of their stuff is SAAMI compliant but it'll still get nearly to 1800 fps with that bullet which ought to be able to accomplish the vast majority of tasks expected by most shooters.

Hey Jon :wink:

I have been reading more and more about 5744 and the 45-70 for low density loads. I need to give some try ...

Marlin 1895 45-70 22" barrel
405 grain Remington JSP seated to 2.54" and crimped with a Lee Factory Crimp Die
Winchester brass, 2.1" trim
CCI 200 primer
48 grain H322 START
55 grains H322 compressed MAXIMUM
Maximum yields 1950 fps from a 22" barrel
Work up carefully from START toward MAXIMUM watching for signs of excessive pressure or velocity
Adapted from Hodgdon #27

Its not near as fun around here anymore when over 28,000 CUP data isn't pole axed by DLA. :lol: :oops: Jackfish and I would be in the proverbial frying pan. :p What I will say is that it really helps to use a chronograph working up these loads.

Great! Thanks for your help guys! The H322 sounds great but I will also give it a try with the 5744.

Thanks again,
Tom

It may not be so fun to discuss going beyond the SAAMI loads without DLA. However, I will only reiterate what jackfish and Dr A said:

jackfish:

Dr. A:

If you look at the loads comparisons using the 405 and H322 elsewhere in this forum you will see that 1800 fps was achieved in an 18 1/2" barrel at well below Hodgdon's maximum and 1900 fps in a 22" barrel (Ruger) at that same level. The components were not exactly the same as what Hodgdon used, however, so also watch that carefully.

DLA had some serious faults. He may have, however, understood the one fact which many seem to overlook when it comes to maximizing the 45-70's potential in the Marlin; that is that it takes a much greater pressure increase per fps when you are close to the 40,000 cup (or greater) levels than it does somewhat below. Obviously, anyone is welcome to try what they will, whether foolish or not. It is worth noting these details considering the somewhat hazy and/or limited credible data available for the 40,000 cups stuff and the potential for those with limited handloading experience to be reading this stuff.

Watch the details carefully.

Thanks for the reminder - I think I am pretty cautious when reloading in general and especially when starting with a new component.
For the 405 Remington I am not really after the "hottest possible load" but was looking for a good starting point. "Normally" I do not even load to SAAMI max and can be sure that I am on the safe side - for anything that I hunt, a good average load with a 1600 fps 405 grain Lasercast bullet will do the trick (48 grains of Varget, CCI200, COL 2.540, Rem brass). And yes - besides being a great toy, I love the chrony just to find out how to minimize velocity variances...
But I agree, it can not be stressed more than enough that reloading and is potentially dangerous if done by somebody who does not care about an/or know the basics.

Don't overlook H4198 or Reloader 7. Both are good powders. For several years I loaded with nothing but Reloader 7, killed a mulie last fall with what became my standard load, 45 grains of Reloader 7 and the 405 grain Remington. Pretty mild, but very effective.

I've found there is no problem substituting the 405 grain Remington for the 400 grain Speer when handloading for my .45-70 Guide Gun.

Some folks seem to have trouble figuring out where to crimp the Remington bullet because it's built a little differently than many bullets. They can be seated and crimped right where the small "step" or ring is on the bullet. This works well. Overall length should be around 2.55 or so to feed well through the Marlin action.

Good luck handloading the good old .45-70, it's a lot of fun and very rewarding.

Regards, Guy

Here I am reviving the dead threads but I've just ordered some of these. My buffalo classic has been craven some so I'm gonna work up a load using the h322. 2k fps should not be much of an issue with a 32 inch barrel:)

Remington 405gr... great bullets, for me it is over 3031. A few years ago I killed a nice 300+ 6x6, Bull Elk, standard open sighted 1895 ported guide gun.

I don't understand why anyone would plink with most jacketed bullets especially for a cartridge that costs a minimum $40 for 50 projectiles....If you look around im sure you can find 50 or 100 405 cast for around $20 or less...Just a thought.

look at 2400 powder as light to rhino loads can be made and in lots of weights. Plinking with a cast boolit is cheaper and they are available. Check Doc Holiday's site for prices and what weights he has. Brain freeze on that data so no help. Missouri bullets, Western Bullet Co., beartooth ullets Dardas, and lazer cast also can help. Have fun and bangaway.

As of last night these boolits were on midway for 40$ per 100 or 160 for 500 which ain't bad! I never use jacketed boolits so this'll be a first for my 45-70:)
