so I picked up a mid-80's NEF Handi Rifle in 45-70. Two questions....What is the hottest load I can cook up for it? And, can I still get the barrel fit work from H&R for other calibers?

Any of the "Marlin" loads will work. Stronger than a Marlin, but less than a Ruger No. 1. I would not use the Ruger No. 1 loads. And yes other barrels will work if it is a factory 45-70, then most any barrel will be fine.
"Industry maximum average pressure for the .45-70 is established at 28,000 CUP; however, most
of today’s SAAMI specification factory loads hover around 20,000 CUP in deference to older black
powder-era rifles and their weaker actions, along with certain modern production firearms.
Most handloading manuals divide .45-70 data into three categories. “Category 1” is for the US
Model 1873 Trapdoor rifles and actions of similar strength, and should never exceed pressure guidelines
of 28,000 CUP. “Category 2” is for stronger actions, with some referring to it as “Lever Action” or
“Modern Marlin Model 1895” data, which is generally loaded to between 35,000 to 43,000 CUP
(depending on source). “Category 3” is for actions designed to withstand the pressures associated with
modern high-pressure cartridges. Examples include the Ruger No. 1, Browning Model 78,
Winchester/Browning Model 1885 (modern version ONLY), Siamese Mauser and Wickliffe. All data listed
in the accompanying charts are “Category 3” loads, which have been tested at a maximum pressure of
50,000 CUP. These loads should never be used in guns of lesser strength."

Not knowing precisely which rifle you have, I would strongly suggest that you make sure you have an SB-2 frame, plenty of info and pics! available over on the graybeard site. The SB-1 frame and all early H&R's had a cast iron frame, the SB-2 is cast, heat treated steel. I'll bet you change your mind about "hot" loads, that lightweight rifle will educate you quickly. Besides, velocity ain't what counts with that cartridge, it's that godawful big hole in one side and out the other that does the job. GW
Edit: no, the Handi-Rifle is no longer produced and service is not available, in fact parts aren't either from the factory. Fitting a barrel is not difficult, mucho info found on the graybeard site.
I have been using trap door level loads with 350 grain bullets in mine, not uncomfortable to shoot, but I wouldn't want much more off a bench and really can't think of anything I'm likely to shoot inside iron sight ranges those loads wouldn't flatten.
According to Greybeard Forum, the Year of Manf. as told to me was wrong. First letter N (NEF) second letter L (1997), Barrel marked SB2Quote:

Per my calculations and tests, the handi rifle 45/70 is strong.
I worked up to 32 gr Unique 405 gr cast, that Quickload thinks is 88 kpsi.
At that point the case head started flowing through the extractor misfit.

The way to calculating strong is thick metal.
The SB2s are very strong, the limit to your load is going to be YOU! I have one of those and really like it, but OH Buddy can it cross your eyes with safe book loads!! Any 350 gr or better cast boolit at 1000fps or better will kill anything in the lower 48 while keeping your eyes in their sockets. heck, lots of deer fall to 300gr at less than 900. .45 is a big hole!
NEF no longer does barrels or guns for that matter, look to the aftermarket. GBO and search engine is your friend here.
My goto load is a 350 gr. RNFP with 48 gr. Reloader7. Minimum 31 gr. for trap door level to 54 gr. for Ruger #1 level. The latter will push a 300 lb man backwards a step and probably not a good thing to shoot regularly. My normal load has enough energy for anything in N. America.
I shoot a Lyman 457122HP in my NEF/H&R .45-70, and only push it to 1450fps, and it does wonders you wouldn't believe. I have pushed much heavier bullets much faster, think a 450gr at 2200fps, and that was just too much of a good thing, but never noticed any pressure signs of any kind. The guys who said that your shoulder will give up before the rifle does are absolutely correct.

You'll quickly determine the hottest load for your .45-70 Handi, when the rifle moves you out from under your hat as it's fired.............:bigsmyl2:

pietro has it! I've had the NEF for years and for my money, you can't beat it. Load to the top of the trap door loads or into the "Marlin" loads, and there isn't anything around ('cept browns, etc.) that will walk away.
I once asked H&R/NEF this question, and they assured me that the Handi Rifle could handle Ruger #1 loads. Personally, I wouldn't consider shooting such a load in such a light rifle - unless I just wanted to experience some serious pain that particular day!
No experience with the 45/70 Handi Rifle, but my guess is that you will give out long before the rifle does. Every 45/70 I have had kicks like a demented mule with heavy loads.
I have a Handi in 500 S&W magnum which had a pressure rating of 65,000 psi. The 500 has a large case head area in front of the rim. Since force equals pressure times area this means that the 500 exerts extremely high destructive forces. I bought mine to experiment with very large bullets at low speeds and it has done well in that application. If you google "12gauge from hell" you might find some insight into the strength of this action.
Most likely your handi can handle a bigger load than you.
That's what I'm coming to realize. Fortunately, I'm old enough to know I don't have to push the envelope of pain just because the platform can handle it.Quote:

10 to 13 grains of Unique. Cast or j. Works for me. No fillers.
