Disappointed In My New 404 Jeffery

[Considering Africa]

Well after waiting months and months, I finally picked up the 404 Jeffrey today. I came home, and I immediately went out back and put some rounds down range. Much to my surprise, the recoil was very significant. “Much more than my 416.” After just three rounds, I was ready to put the rifle down. I went to the safe and got the 416 Rigby and shot it a few times. After shooting the Rigby and realizing the recoil was much less, I installed the muzzle brake that came with the new 404. I then shot 3 more rounds and the recoil was significantly less, I would say around 40% less.

“Both ammo was factory Hornady”

The 416 weighs 11 lbs and the 404 weighed in at 9.2.

I found the felt recoil of the 404 very surprising. What are all of you guys think?

There are several recoil charts available comparative recoil charts on the web. They show loading of a 400 in the 416 and 458 Winchester 416 has 52 foot pounds of recoil felt, the 458 shows 55 projectile. When I went to a different chart that compares the 458 both Winchester and 458 lot with the 404 Jeffrey the 404 Jeffrey with the 400 green projectile shows 55 pounds of recoil. These charts are all available via Google Chrome.

I've said it a thousand times. A 400 gr bullet at 2350fps is a 400 grain bullet at 2350 fps. No matter what case it comes out of. All this nonsense about the 404 being some pussycat to shoot is BS. Gun weight and stock fit are infinitely more important than any slight case design differences. When the 404 came out it was loaded to 2100 fps or thereabouts. If you load any of the 416 rounds to that level you'll have an easy shooting load as well.
My Winchester 70 416 Rem Mag weighs in at 9lbs even with scope mounts only, no scope. With scope it comes in at 9lbs 14 oz. Loaded to 2350 fps it is no pussycat to shoot either. But it is shootable nonetheless. Especially since I had the stock lengthened to my correct LOP.
Did you have your 404 made to your correct LOP?

I agree mostly with you but the amount of powder is also a consideration. In this case, 416 Rigby vs 404 Jeffery, it's not a factor. I can tell you both by math and feel shooting my 500 Jeffery with H4898 vs IMR 4350 is a substantial difference with the same bullet and velocity.

With the IMR 4350, what amount or grain-weight (roughly) replicates the original .404 Jeff velocities with a 400grn bullet, i.e., 2000-2100fps?

I'm shooting 400 gr Barnes with 80 gr Accurate 4350 and though I don't have a chronograph, judging by felt recoil I'm guessing about 2200 fps. I started at 77 gr and got very good group but was pushing primers ( = not enough gas) so I jumped it up to 80 gr. Accurate and IMR seem to perform about the same. At the time IMR4350 was unavailable due to pandemic. Accurate powder seems to work so I stuck with that load. At fifty yards bullets land on each other and recoil is stout but manageable. I tried loading 307 gr bullets with H4895 and the recoil was just too much. Still trying to find a powder/load that will work with that bullet.

Tried AA5744? The Woodleigh 350grn RN SN bullets really liked it.

What is the weight of the gun?

What is the weight of the gun?

More importantly how is the stock fit for you.

Thanks. What's an equivalent North American powder brand?

 

[Ontario Hunter]

What is the weight of the gun?

Over ten pounds loaded.

More importantly how is the stock fit for you.

LOP may be a little short but not significant. I will be getting a NECG recoil pad that's a half inch longer. 30mm scope is mounted very low. Actually had to shave a very tiny amount from bolt handle to get complete clearance. I can now pass a dollar bill between bolt handle and ocular bell when bolt is opened.

You guys are really close. If it was me I would go into QL and enter my desired FPS of say 2150 with a 400 grain bullet then run through different powders to find the one with the lesser grains within safe PSI…that load will generate the lowest recoil and deliver your other requirements

5744.

Can you mount the rifle with eyes closed, and when you open them you are looking through your sights? Or sight, close eyes, relax grip, then tighten grip open eyes, are you still on POA or very close to it?

yes, this is a basic rule of physics - energy is energy

This is true but stock fit, more than weight, will determine how that energy is transmitted to your shoulder.

Also the design of the cartridge case and powder used will contribute to the energy produced.

Yes. But that is because scope eye relief has been properly adjusted. Iron sights line up very close with the mount-and-open-eyes test. The LOP for my Springfield 03A3 seems more natural and it has LOP that's about 5/8" longer. The 404 scope will just touch me sometimes. A half inch extra LOP should take care of it.

This should mean you have very good rifle fit and felt recoil would not be as bad as from a rifle that was a bad fit. Other things come into the fit but a pleb like me is not up to speed with this like a good stock maker.
