Can anyone tell me anything about the 470 Capstick? Am I correct that this cartridge is based on the full length H&H case and being based on that case is compatible with any action suitable for the 375 H&H? If you happen to shoot this round could you tell me about your rifle and any load data you might have? Thanks. Craig | ||

It is indeed an opened-up H&H case, thus can be used in any suitable action using this length of case. 'George S' seems to be the resident expert in this cartridge, he shoots one, and has hunted Africa with it. I'd suggest asking him for load info. ~~~Suluuq | |||

I will be building one for a client as soon as the Krieger barrel arives, hopefully in a week or two. It's on a M70 Classic, blued action, CrMo barrel. Any action with a 3.6" or longer magazine will work. It's just H&H brass with the largest bullet that will fit the almost straight cylindrical brass. If you are interested I will post a photo of the cartridge and a 458 Lott & 375 for comparision. | |||

I have one on a mauser 98 and I am very pleased with it. It is far more accurate than my 458 lott. | |||

Craig, I have a Winchester M-70 .470 Capstick. It started out as a .375H&H; it has a 24" Pac-Nor barrel, NECG 3-leaf express rear sight, barrel band front sight w/hood, re-inforced stock, 2 Dead Mule recoil reducers, and a KDF brake (and thread protector). The guns weighs 10.75lbs. unscoped. Currently, it wears a Burris 2.5x in Kimber-style lever QD rings. I get 2380fps w/500gr. Woodleigh bullets using IMR-4064. Muzzle energy is 6300ft.-lbs. Recoil is 74ft.-lbs. Here are some pics:      That's a .375H&H on the left, the .470 Capstick on the right.  A .470 Capstick round next to a .270 and .22-250. Impressive, huh?

CraigP, I have a custom shop Model 70 I purchased from Winchester at the SCI show in Vegas two years ago. I have not shot it yet though. I have two boxes of loaded ammo form Superior Ammo and have proper headstamped brass. Brass can be obtained from www.huntingtons.com. If I didn't have my heart set on killing my first buffalo this July with my 470 double, this rifle would be going with me. Jim Miller | |||

George, I am trying to think if I have seen that scope before... | |||

Dan, That's a 2.5x that I've had for a couple of years. The 1.5x I bought from you may replace it, or I may put it on a 'hog & bear' rifle I've been thinking about (.458x2" on a Savage short-action). George [ 03-15-2003, 21:55: Message edited by: GeorgeS ] | |||

Thanks to everyone who responded to my questions. I just bought a set of dies for the Capstick and am planning on building one in the near future. If anyone would like to e-mail some of their load data I would really appreciate it. Again, thanks to everyone who responded. | |||

Craig Check back in this or the Reloading section in the near future. That 470 Capstick that John Ricks is working on is mine. I will be trying out lots of different combos when I get it. According to Quickload, Varget looks promising as do most powders that are suitable for the 416 Rem or 458 Lott. Varget also works great in my 416 Rem. | ||

I like 84 to 86 grains of IMR 4064 behind a 500 grain Woodleigh, Trophy Bonded Sledgehammer or GS Custom solid. F215 primers. But, I plan to re-do my load development and try out the Bridger Bullets nose styles #3 and #4. | |||

quote:David, What sort of powder charges does QuickLoad propose? What velocities does it predict? Thanks, George | |||

quote:I've been doing all my Quickload modeling assuming I will shoot 500gr Woodleighs, both FMJs and SN in a 24" barrel. It looks like a max charge of Varget with the FMJs would be about 82gr for 2280 fps and for the SNs, 84gr for the same velocity. Both are slightly compressed loads. When modeling large bore straight wall rifle cases, Quickload tends to predict higher and faster than actual pressures and velocities. It states this in the Quickload manual and I have found this to be true with my 416 Rem Mag. The predicted velocities were about 75 to 100 fps faster than those that I actually measured. My intention is to load my 470 Capstick to the same velocities as the 470 NE, about 2150 to 2200 fps since that is the cartridge in which most bullets of this size are intended to be used. I also ran several other powders in Quickload, IMR4064, IMR4895, H4895, H322, H335, W748, and RL15 and all give pretty much the same predictions. The charges appeared to be either compressed or very nearly so. I few predicted velocities as high as 2350 fps before going over pressure. It looks as though anything slower than Varget would have to be heavily compressed where Varget is just barely compressed in the predictions. The main reason I am looking so hard at Varget is Varget's temperature stability. I shoot Varget in a 6BR 1000yd Benchrest rifle and my exprience shows less than 25 fps average velocity spread between 60 deg days and 95 deg days. This also tells me that there is probably not much pressure variation over this temperature range either. [ 03-18-2003, 03:29: Message edited by: David ] | ||
