225 gr 8mm ?????

[leadhead]

Hi Guys,
I'm wondering if any of you guys have used the lee 8mm Maximum
boolit that midsouth sells as a special mold?
I just ordered one and was trying to find out if anyone has used it,
and what were the results.
A few loads would be nice also.
Thanks,
Denny

How about this :

BY THE WAY, MINE ARE SIZED .3245 DIA.

It works fine in all of mine IF I seat it right down to the top of the front band and work the bolt rather vigorously. Mausers don't like large meplats, which hang against the edge of the chamber.

I haven't yet tried my 8mm Karabiner mould, which has a slightly shorter nose. Ought to help, but it'd still need to be seated to the same depth. This seriously decreases the powder space available.

I'm an IMR 7383 fan. The amount that will fit under the bullet without much compression is perfect. About 2.8 cc I think, or about 37 grains. Velocity's around 1700-1800 FPS from my various 8mms.

[waksupi]

Keep in mind, Mausers were designed to be worked vigorously. None of this "push them in slow" for old Paul Mauser. Same goes for ejection.

[Ricochet]

Right, but if I seat that Maximum bullet out to land contact length, I can't work the bolt vigorously enough to get the cartridge to chamber. It jams very firmly against the rear edge of the chamber in all of my Mausers with certain cartridges in the magazine stack. For some it's one coming off the right side, in others it's coming off the left, and in some it makes a difference whether it's the first or last. Whichever way the bullet is pointed as the cartridge angles up the feed ramp, some will hit really hard and jam. For reliable feeding, the only fix is to deeply seat the bullets. Round or nearly round nosed bullets with small meplats are no problem. I can seat that Group Buy semispitzer right out to land contact, not a hiccup in feeding.

brand new member got a karbiner mold the other day in the mail.shot my first shots yesterday . 28 grs imr 4895 3 in. group 29 grs imr4895 4in. group 30 grs imr4895 5 in.group . looks like im going the wrong way? this is at 100 yards

Oldarkie,

Welcome aboard. Sounds like you're in the ball park. IMR-4895 is a good powder to start with. Try reducing your load as well, a grain or two.

Good shooting,

[leadman]

oldarkine, what gun and cartridge? What is your alloy, gas checked? lube?

Any leading after the shooting?
Be aware these boolits are long enough you need to make sure they are solid enough when dropped out of the mold they don't bend slightly on you.

[Kraschenbirn]

Don't have the "Maximum" but the Lee Karabiner (sized to .325) feeds just fine in both my Kale Turk and my DWM 98k and, loaded over 29.5 gr of H4895, will match ball ammo accuracy in either rifle.

thanks for the welcome uber7mm i was so encouraged by my first test i had to get back after it,so i started at 26 but 27 was just right, shot 13/4 at 100 in a high wind. im shooting and old k98k 8mm. 9lbs ww 1lb 50/50 ,hornady gc rooster red lube sized .325 .never thought about them bending should i try dropping them in a pan of water

[legend]

Ben, darn it... you always shoot better than i can.

ok, it's a bit off topic but I like showing off my 8mm targets. :)

I didn't have any good when trying the Karabiner boolits and would have settled for 3" groups. Sold the mold to a friend and went back to .30 or .35 caliber without aggravation. Happiness is found where aggravation is absent!

[UBER7MM]

oldarkie,

There's different philosophies regarding air cool and water cooled boolits. I'm not out to start any heated debates. I happen to water quench them but only because it's safer to handle them quenched. I drop them into a 5 gallon bucket with about a gallon of water. Water in the mold is a bad thing, however. Whatever you're most comfortable with. I believe that you'll develop your own methods.

Good casting,

[Dutchman]

My 8mm Maximum double cavity from MidSouth cast a too large bullet for 8x57 Mauser. The nose is too large, body is too large. Another worthless purchase of a Lee "custom" mold. That's two with the Cruise Missile mold.

[oldarkie]

thanks uber7mm im pretty green at this stuff and welcome all advice. i will try water quenching next time i cast

My Karabiner mould does not want to fill out. I've tried all the tricks. I've run it hot, I've increased the tin content, and I loosen the spure in hopes of venting better. It just doesn't want to fill out properly.

Anyone else have this problem?

Everett

[oldarkie]

was having the same problem . turned up the heat and started casting faster, seems lee molds cool faster than steel molds. boolits are almost frosty. works for me .good luck

Who sales the Lee 8mm Maximum mould?

Yes, besides venting at the top you may need venting at the bottom. Also you may need to change your technique- try tilt, swirl, gap between nipple and fill hole. Its all about letting the air out as well as the lead in, before it cools.

Leadhead,

BTW:

The Lee's 8mm Karabiner molds drop 235 grains casts. I believe that the 8mm Maximum will be more in the 245 grains range. Perhaps someone with a Maximum mold can verify.

Good casting,

[Jim]

The max drops around 250, depending on alloy.

Anyone tried launching with WC872 or WC867? I was just getting ready to try one of these molds. Anyone want to sell theirs?

[1Shirt]

My Karabiner is no good for my Swed 98, due to little if any throat, but will shoot the Maximum ok and chambers without problem. Regardless, both are long enough to be below the neck. So will probably sell the Karabiner in the near future, and will be wringing out the Max for best load.

Thanks, this is the info I've been looking for, for the last week or two. Guess I'll put in and order for some Wideners or Bartlett powder. May post on the group buy forum and order a case of six to save the hazmat.

PS: Did you get a clean burn with the big slug up front? What was accuracy like, relative to other loads in the same rifle?

Notes do not say and this was June of 2005, they do say 5-.871" @ 50 yds, 70*F ES 19fps- pushes bullet out of case after a day-crimp

A lot will depend on the lot of 872 you get :), think I have went through about 4 different lots, the one listed is the fastest and cleanest and came from Bartlets 4 jugs-32 lbs. In several large capacity magnums this lot was a full 200 nfps faster than the slowest lot from Pat's, although it is still slower than any of the 3-4 lots of 860 I've tried. Their are several other surplus powders that may interest you T870-T5020-T5070 Laveen, AZ, don't know if Red is still there or not.
