Reloading 404 Jeffery

[Roughneck]

Hey guys was wondering what powders or loads you recommend for the 404 Jeffery. I have following powders available- IMR 4350, Accurate 4064 and Accurate 4350. I will be shooting a 400gr Hornady bullets and Barnes 400gr TSX. Any info is greatly appreciated. I wanted to try to keep the speeds somewhere around 2200-2300 preferably. thank you.

I load 80 gr Accurate 4350 behind Barnes X and TSX bullets. No chrono but I estimate they are running about 2200 fps. The load data given to me said start at 77 gr with that powder but those were too soft with primers pushing out. 80 gr group well and recoil is tolerable (barely!). Try it at your own risk, of course.

If you look at the thread on history of 404 recently revived a couple days ago, you will see images of a published compilation of various load data for 404 on page one. Be advised the old boy who is cited for many recipes liked to load em hot! Start at his minimum ... and consider staying there. I tried his recipe for 300 gr Hammer bullets and IMR4831. Boy, did they buck! Absolutely flattened one primer. I quickly gave up on those bullets. The original poster of that thread is no longer with us so you cannot message him. He also liked to supe his 404 to 2300 fps. There really is no point in gassing up 404 to those speeds. Just as well go buy a 416 Rigby ... and make an appointment with an orthopedic surgeon.

OH, appreciate the info and I will give that recipe a try. Will also look for that thread. Thanks

Thread '2023 Range Report: 404 Jeffery w/ 400 gr Swift A Frame'

Feb 13, 2023

A few years ago, I bought a used Win M70 Super Grade in 300 RUM and had it converted to a 404 Jeffery. I purchased a bunch of Hornady and Swift factory ammo, as well as several boxes of 400 gr Swift A Frame bullets, Federal 215 primers and 8 lbs of H4350.

@Shootist43 gave me a magic load, which he got from @Von Gruff: 400 gr Swift A Frame over 84.0 grains of H4350. Since I hadn't reloaded in 30+ years, I went over to a friend that is big into reloading and got a little refresher coarse from him. Using his reloading equipment and MagnetoSpeed, with my dies and components...
