Member Posts: 10,035 ✭✭✭✭
I just bough a husqvarna m-98 in 8x57mm, I have some 195 gn. Hornady bullets that just seem to belong in it. BUT my hornady loading book (or any of the others) done list this weight. Any body else out there have any loading data for this bullet? thanks

Also, have you looked on Hornady's website for updated reloading info? They may have some.

Generally what I've found is extremely good accuracy...like in the .4'-.5's with heavier bullets loaded down a bit..like 2400-2500. When I've loaded mild for the 8x57 it usually ends up with a big 'one-hole group'. When I push mine out as fast as they can reasonably go I get 2-2.5" groups. The 200 gr. Speers are getting really good groups with 48.6 grs. of 4064. When I go up that extra 1.4gr. and get that extra 100 or so fps the groups spread right out.
To date the best group I ever shot with mine was a .210(5 shot) @ 100 yds. using Yugo 170 FMJ spitzer stuff that went out at 2360 fps. I couldn't even get on the 300 yd paper (22 in.) it dropped so bad...but it hit the same place every time. It shot a sub MOA group (2.375") @300 when I got it up there, though.
Another thing you might think about doing is taking down Turk rounds(some say this is blashphemy) and cutting the 48.5 gr. of flake powder used down to 47 gr. and stuffing a good quality bullet in the case. Or, transferring that powder to a case prepped already. You'll end up with a 150 gr. going about 2800-2850 instead of the high 2900's that you will experience with full power Turk. The reason I alluded to blasphemy is that some folks aren't sure if the powder is corrosive. I can't say if it is, but it sure is consistent. Hot or cold the stuff stays within 20 fps total variation over a day of chrono'ing 60-80 rounds. And when downloaded the groups get tremendously better. So, my experience has shown 150's getting good groups but 170's getting the best and 196's and 198's showing in the .5MOA several times...if loaded a little slower.
Edit:
Mike, your'e right they won't give it away, even to update their latest reloading manual. I thought I got some updated information from them once. I was really disapointed in their latest two volume manual though. It doesn't even come close on some rounds that I'm working with.
I got some good info off Sierra when they turned out a new bullet. If they have anything new in 8mm they might still have the updated information available.

I still have the better part of a 1000 rounds of the Turk. It has performed well in the K98k rifles in which I tried it, but as you report, it is hot. You say the bullet is a 150gr.?
Okay, I am going to try that and if it works out in Nephew's rifle, I can just pull the Turk bullet, reduce the propellant, as you wrote, and re-seat a soft point 150gr hunting bullet.
How much should I reduce the Turk load to re-seat the 170gr Speer semi-Spitzer?
Since he killed his deer, he is believing that the 170gr bullet is magic for him!

Pinhead,
I have found that 4895 gives great pressure in the 8mm, I do nearly duplicate Turk loads with it too. I just haven't gotten great accuracy with it from My Yugo(scoped)like I have with 4064. But, it is always right up there with the velocity. I haven't worked any loads up in my sons Rem 700 yet though.

Much 8mm load data is garbage; and misprinted. For instance, Lee's Modern Reloading and IMR both list something like 35 gr of 4064 as the MAX for a 170 gr. bullet..... developing a velocity of 2200 fps. No way. Try 1600 fps, double checked with two different chronographs from two different guns. Point being, you can get some great info online, or else work up your own, but regard most data in manuals as a start point.

I find that true with the, .257 Roberts in the new manuals, the 7x57 and 8mm Mausers. I never have a problem starting at their max. Of course all the new manuals new cases report velocities that could almost hit Jupiter... That is until some experts like us get in and work up a bunch of our own loads.
