Any one own one?
I think I can get a 375 hh action off a Buddy very reasonably and I've always enjoyed Peter Hathaway capsticks books.
It's faster and bigger than my 458 wm
Having a 45/70 a 458wm and a 458-2" in the works building a 458 Lott seems lacking compared to something else in a different caliber. I'll be getting into moose hunting and enjoy big bores. Also African cape buffalo and South American water buffalo is on my list as well. I originally bought the 458 wm for such adventures but it has become my favorite bear hunting rifle
The action is a cz550 with a grossly huge stock
 
I just traded my No.1-S 45/70 for a No.1-H 450/400 NE 3"... I had Bullet Barn make up some .411" 370 Cast FBRN's and want to tailor a load to 2000 fps with a ballistic filler... just a medium 45/70 with panache... it will likely only perforate spring bears and late season flopheads... but fun.
 
Way more bullet choices with a 458 Lott and fires a 500gr bullet faster than the 470 Capstick. Plus a 458 Lott can fire 458 WM ammo. Here's my Sako AV 458 Lott.

BB......Although someone somewhere decided to call it the 470 Capstick it was developed many years back by P.O. Ackley and is (at least in my opinion) correctly called the 475 Ackley. It does in fact over shadow the 458 Lott by a bit and even the 450 Ackley by a tad. This is totally logical of course because it has greater powder capacity driving the same weight bullet with a larger diameter. Does it matter? Not likely, but some say it has greater stopping power from a little more velocity and greater frontal diameter.
It used to be that the 458 diameter cartridges made more sense from a financial and bullet availability standpoint, but given my search of late for 500 gn 458 bullets I would say they are all about the same now. Woodleigh make great 470 bullets and they are available through several dealers here in Canada.........they're not cheap, but then neither are 500 gn 458 bullets anymore.
I have a barrel and was trying to decide between this cartridge and one I designed on a shortened Rigby case.......then I bought my double 470 NE instead. Still have the barrel, still haven't decided what to do with it......I'll build something with it someday I'm sure....might even be a 475 Ackley. I do have about 400 X 416 Rem cases that would pop out nicely..........

That’s a nice setup. A bit light with full power loads, but should be fun with slightly reduced loads. Reloder 15 with some filler should do the trick. IMR 4831(in my experience) produced a factory-duplicate load, performance-wise.

Trailboss with a Mountain Mold Co. ~410 gr. Flat nosed bullet with gas check proved to be a great plinking load.

Thanks for the info... I have RL-15 and H4350 to use with Puff-Lon ballistic filler... 2000 fps is the target but will test to see where these bullets tune up. From what I have read, 30.0 grains of Trail Boss with 350-400 grain cast is a good plinking load... will give that a try.

I am mounting a VX-3 1.75-6x32mm on it...

450/400 3" is a cartridge I must own but I want a double
Doug I know capstick had nothing to do with the round it was just named after him. I can't afford a double in 470 nitro and don't know of any single shots. The 470 capstick seems the most economical way to get something bigger than a 458 that uses smokeless. I considered a double in 470 as a financial goal but the 450/400 won out as it can be lighter and I feel it's a more balanced cartridge for what I'd use it for.
I'll still drag my baikal thru the swamps for bear but I doubt I'd take it to Argentina or Africa for either buffalo. I'm giving up buying a 370z so I can travel to hunt. I need to go before I'm 40 so my knee can hold up

The Lott makes more sense but i've read with a cz550 all that's needed is a new barrel and second recoil lug. The gun is just to big for a 375 hh. Or I buy it cheap and sell the action and stock to fund another project
 
458 lott is great. Personally i used a 458 Express 3” on a brno action. Just a stretched lott. Could shoot 458 WM, 458 lott amd obviously 458 Express 3”.
Then had a 475 A&M Magnum built on a cz550 action. Brass easy to find, but 475 bullets that work well, not as easy to find. 458 bullets just really easy to come by and if you get stuck in Africa without your ammo (airlines etc!!) you will find 458 win Mag and Lott ammo easy.
 
Ideally I'd like to bring at least 2 rifles. I though theyd be a 300wm and 458 wm however the 400 gr ppsn woodlieghs shoot flat enough and seem to expand well while staying together that I've been questioning the need to bring a 300.
Buffalo
Wart hog
2x Zebra
Oryx
Kudu
Impala
And a baboon an hyena if possible
I'm told shots aren't generally over 200 yards so my 458 is flat enough. I've been told a 400 gr 458 at 2400 fps is Ok for buffalo. However more punch is never a bad thing

Wife says I ain't allowed to shoot an elephant
 
the capstick will reach 2400 with the 500gr, will surpass the 458lott by about 50fps, strange its listed at only 2150, unless its loaded to just equal the 470nitro
damn now i want to build another capstick

30.0 grains of Trailboss is certainly within the 25-32gr range (using Hodgdon's guidelines). I found that, with the cast 410 gr Mountain Mold Co. bullet, the darned thing was actually regulated at 50 yards (!) - Practically speaking, similar to the factory test target. The load was a powderpuff to shoot and the accuracy was surprisingly good.

For full power loads, I would suggest trying IMR (or H) 4831. Fills the case, performs with authority.
 
grit..........I suspect you hit the nail on the head, loading the 475 Ackley (470 Capstick) to exactly match the venerable 470 NE. Because I know for a fact that it is capable of over 2500 fps from a 25" barrel in a 602 Brno, using 500 gn Star bullets, which are very similar to the old original Barnes.
 
I read somewhere that the difference between the 470 Capstick and the 475 ackley is the presence of a "false shoulder" to better keep the round cantered in the chamber. If you look closely at pictures of the 470 capstick ammo there is what looks like a very aggressive factory crimp, and I think this is what they're talking about. I believe it was developed by A-square.
 
Any difference between the 475 Ackley and the 470 Capstick are imaginary as there just isn't anything you can do with a full length 375 H&H case blown out to accept a 475 bullet. Even the shoulder on the 450 Ackley is almost nonexistent and plays virtually no role in the cartridges performance. The powder capacity gain is not worth talking about and is really irrelevant......the 475....even less. Let's put it this way, the differences between the original 475 Ackley and the newer 470 Capstick would never stand up to "patent law" scrutiny. There just isn't enough difference to be classed as a different cartridge, or even an "improved" cartridge, for that matter.
However, whatever you wish to call it, it is a very formidable cartridge and a step up from the 458 Win, 470 NE, and even the 458 Lott. It should be a better "stopper" with greater frontal diameter and equal or better velocity than any of the afore mentioned group.

Depends on the bullet.
If you are willing to commit to weird size bullets consider the 400 H&H.

I have always liked the idea of a CZ rifle in 460 Weatherby,
3+1 capacity maybe 4+1
easy to get 2400 fps with a short barrel
good component availability.
