Disclaimer: Below data proved safe in my Ruger No. 1 rifle. Always follow safe handloading procedures which includes starting min. 10% below maximum loads and work up. Any component substitutions also require one to start low and work up.

Some of the loads below SHOULD NOT BE USED IN DOUBLE RIFLES! I will point those loads out with a WARNING.
-----------------------------------------------------------------------------------------------------------------------------

Periodically folks will be looking for some data to give indications of where to go with regard to loading for the 450-400 NE.

There seems to be a lack of data out there, especially with the 300gr bullets, so I thought I'd share some data from my Dope Book.

All loads below are using Hornady brass and Federal 215 primers. Velocities are instrumental at 15 feet.
-----------------------------------------------------------------------------------------------------------------------------
300gr Barnes TSX (.411")

Reloder 15 with 4gr Dacron filler. OAL 3.74"
58gr Velocity 1,883

IMR 4831 OAL 3.73"
80gr Velocity 2,095
85.0gr Velocity 2,250
86.5gr Velocity 2,337 (DO NOT USE IN DOUBLE RIFLE)
88.0gr Velocity 2,399 (DO NOT USE IN DOUBLE RIFLE)


300gr Hornady SP (.411")

IMR 4064 with 4gr Dacron filler. OAL 3.57"
60gr Velocity 2,020

400gr Hornady DGX (.410")

63gr Velocity 1,999

IMR 4831 OAL 3.65" (temp 85F)

87gr Velocity 2,319 (DO NOT USE IN DOUBLE RIFLE)
88gr Velocity 2,339 (DO NOT USE IN DOUBLE RIFLE)


400gr Hornady DGS (.410")

71.5gr Velocity 2,089


400gr North Fork (.410")

IMR 4831 OAL 3.793" (Temp 80F)
80gr Velocity 2,092


Sorry I did not record the temps at firing for all loads....but they were all between 60 and 85F.

Please read the above data carefully. I have reviewed several times before posting to make sure I didn't have any typos...but you are responsible for doing a reality check!!

Good shooting!

More data from the Ruger No. 1 450-400. This time with the new-to-me IMR 7977

Please read warnings in post #1 before reading further here. These loads were safe in my rifle. Start low and work up carefully!

Velocities below are instrumental at 15 feet. MV will be a frog's eyelash higher. ;)

400gr Hornady DGX (.410")
IMR 7977
Hornady brass
Fed 215 Primer
COAL 3.75" (my rifle has a long throat. Not crimped in cannelure. I have turned down my expander 0.0005" for tight grip on the bullets)
Temp: 85F

90gr 2,120 fps
91gr 2,152 fps
92gr 2,179 fps (DO NOT USE IN DOUBLE RIFLE)
93gr 2,229 fps (DO NOT USE IN DOUBLE RIFLE)
94gr 2,243 fps (DO NOT USE IN DOUBLE RIFLE)
95gr 2,266 fps (DO NOT USE IN DOUBLE RIFLE)

All cases extracted easily and expansion of the brass was normal at the web area.

If using this case, primer, bullet, powder combo in a double rifle, I would start at 85gr and work up carefully, watching for signs of excess pressure.

Do not hot-rod your double rifle! I strongly recommend the use of a chronograph for all load development, but especially for a double rifle.

Good shooting!

Mule deer and Colorado elk seasons almost done! Hunters driving farm roads, looking for racks, their PH driving them along, I ask that you not pull into my drive. The buck behind me, on the boundary line of the GMU somehow knows. The hunter laughs, I would invite you in to see my Searcy rifles but social distancing prevails, darkness arrives and the buck slides away into secret tree grove...

Ellwood Epps has 1 box of 25-20 in stock. Look them up on the web. They are located in Orilla Ontario.

On the vx6 2-12 what does the zl2 stand for?

Thanks, Oliver

Many thanks for re formatting my article for the forum

I served my time in both the bush and during the bush war

I hope it did it justice

Good morning friends

i‘ve taken to heart a suggestion to tell my story about a lion hunt 37 years ago. ‘I don’t know, but am thinking there are site rules as to posting and file type. Three of the four posts (chapters?) are done, I took time away from here to write up the story. I have a couple of photos too.

also, I’m going to dissemble the rifles and see if Butch may have signed them. I’ll let you know.
