The old Mauser surprised me today after running some handloads over the chrony.
The 195 grain Hornady loaded with 46 grains IMR 4895 clocked 2491 fps.....:cool:
The 220 grain Sierra's loaded with 45 grains of H4895 clocked in at 2487 fps..:eek:
Rifle is a postwar Brno in full military wood with the original sights. I got 8 shots under 2 inches at 50 yards,I think that will be ok to hunt with it.:dancingbanana:
Thanks to hs4570 for the chrony results........:wave:

I found some old 35 Whelen chrony data to compare to the 8mm....
225 Speer
52 grains IMR 4895
2412 fps

I have nothing but respect for the 8x57. While my rifle is a modern, commercial action, I have been impressed at the velocities possible with various bullets using the right powders. I have exceeded 2800 with the 175's & 180's using Vihtavuori N550 & N150. N550 has also given 2600+ with the 195 Hornady, 200 Accubond and 200 Partition. All these will shoot around 1-1¼" at 100 meters. I have shot a couple of moose [125 meters and 260 meters] and a big black bear [75 meters] with mine. All died right there, and I have yet to recover a bullet. Regards, Eagleye.
 
I checked Norma's website and their velocity for the 196 grainer is 2562 fps, I got pretty close with my first handloads getting 2491 fps.:dancingbanana:
This load is very accurate and should flop'em pretty good..........
 
I've got a Turk rifle cut down to a carbine and with a 20" pipe I was only getting 2350 fps with the Norma 196 grain factory load...And it works just fine!

If you get an extra 100 fps plus over what I do...you ain't gonna have any problems at all!
 
Worked up to 2670 fps last Weekend.

Sierra 175 Grain SPT - IMR 4064 . I would like to get a hold of some of those Vihtavuori powders like N150 to see what kind of velocity I can work up to.

Looks that Model 98 is gonna need a better recoil pad. My old man's is not enjoying the recoil with that Hockey puck !
 
I got to buy a chrony. I reloaded using 195gr Hornady sp and 48gr H380. With my k98 I got 1-1 1/4 groupings open sight at 50m
 
when i had one, the norma 196 stuff ( which was really HOT, BTW) chorno'd at about 2800-had the "small" stock on it too, plus a recoil pad and it still kicked like a mule-the winchester factory 170 stuff wasn't near as bad
