Help with heavy cast 8X57 recipe

[johnnybar]

I have cast muzzle loader ball, conical, minie, modern pistol and revolver bullets and had good luck with them thanks to info from Lee and board members here. Now I want to produce a heavy 215 or 225 grain 8x57 load for the many Mausers I have (48, 48A, 98/22 & VZ24's). Need to know leading free fps I can expect with and without gas checks. I need advice on: alloy, which Lee mold is likely to work best...8mm Karabiner 215gr or 8mm Maximum 225gr, use of WC867 or WC872 with no duplexing preferred, std or mag primers, etc. I have lots of hard birdshot, soft lead, and can easily get wheel weight alloy to copy recipes. Please point me in the right direction for success. Thanks

I had great accuracy with my Turk 38 with the discontinued Lyman 323471 at NO MORE than 1400 fps. Over that, and it shot 2' patterns @ 30 yards. I used GCs. WW alloy. Don't remember the powder.

[johnnybar]

Is that a common speed limit with GC's in other long guns?

Seems to be what I am getting with my 8mm-06 too.

Must have been stripping the bullet. I see others on hear getting near 2000 fps with long bullets.

my 8 mauser wouldn't begin chambering a long boolit like that,170ish is about it's limit.
i generally keep it in the 1900 or so area with a fast powder like 2400.
but can push the envelope with 30 grs of imr 4895 easily enough or an even slower powder if i wanna go a bit faster.

[HARRYMPOPE]

30g of H or IMR 4895 or 16g of 2400.i shoot this with the Lyman 323471 and the 323378.The 2400 load is most accurate.My Mausers wouldn't chamber the Lee Karabiner bullets without deep seating due to the oversize noses for my rifles.

My Mauser chambers the Karabiner perfectly, I use 35gr H4895 for around 1,850fps.

I shoot the 175 gr lee boolit ahead of 17 grs 2400. Lubed with LLA. Quite accurate and no leading in any of my Turks. 1700 fps

For my Turk ATF Mauser I ask Tom over at Accurate Molds if he could make a mold using the spec's of .313 bore x .328 groove using his catalog drawing of 31-180S. He did but had to increase the radus from R1. to R.75 which was fine as I did not want to increase the length or the meplat of the bullet due to cartridge oal. I shoot this bullet at 2000 fps using 40.4 grains of H4350 and place a 4" group at 100 yards using as issued military iron sights. Tom now has this bullet listed in his catalog as bullet 32-195S. Best wishes to all, Bruce.

...........In the interest of a heavy for caliber 8mm boolit I commissioned a GB through Lee on the Cast Boolits board for the above slug maybe 8 -10 years ago. Due to it's length, at the time it could only be done in a SC set of blocks. It was called C326 - 240 - RF. In most alloys it dropped between 236 & .238 grains. I worked up several succesfull loads for it in 3 Turkish Mausers (M1888/35, M38, and a M38/46). One load in particular was very accurate in all three, It was a ful caseload of TCCI 5020 ball. From the 29" barrels it was doing about 1950. I experimented for higher velocity using surplus WC852 (slow) using the M38/46 (24" bbl) and stopped at 2300 fps. It was all the fun I could handle, and it cracked the stock in the wrist by that time :-) You'll just have to try them and see what you can do. There's no publish load data for those 2 heavyweights currently available but I'd sure start with a slower powder under a solid filler like Grex or other shot buffer, and work up from there.

This is an easy load that will be accurate for the beginner and novice.

Thanks for all the recipes guys. Has anyone used surplus IMR7383, IMR5010, wc857, wc860, wc867, wc870 or wc872 behind any of the 175 to 245 gr offerings? They are really priced right...$39 - $72 per 8#, with no hazmat on a couple of them for 6 jug orders.

[johnnybar]

Anybody out there? lol
Now my powder question is limited to IMR7383, WC860, WC870 and WC872. Surely a few of you are using these $5/lb powders for heavy bullet loads in medium to large capacity for bore cartridges.

[khmer6]

Check out cast pics. They have load data on surplus powder. I do believe a full compressed load won't generate dangerous pressures. Don't quote me on this though. I have yet reloaded this round, but have a case of wc860 coming to me soon to try

Here's a screen shot of some data

I shoot 7383 under the 8mm maximum boolit in my 24/47 with exceptionally good accuracy. Can't overload the case with it, but a case full minus about 1/2cc for some filler, I use Cream 'o' wheat, allows it to go 1800 fps and shoot clean without gaschecks.

860 works well if you duplex it. I use 5gr. IMR4227 under a compressed load of 860 and a paper patched Ranch Dog 165 30 cal. boolit. It runs around 2400 fps with close to MOA accuracy and shoots clean. Without the kicker charge it is very slow and dirty, and not terribly accurate with loads of vertical from the inconsistent burn.

Thanks for the link. I wasn't sure on the rules on linking to other sites. Lots of other forums ban you for posting links :banghead:

[runfiverun]

that's a link to cast pics
had to scroll down 4" to the link to get the spelling right.
there is a ton of valuable information there and well worth reading all of it.

[johnnybar]

Thanks guys! Great load info coming in from everyone. I really appreciate it...makes the powder decision go from iffy to go-for -it.
