2. 11gr., 55gr Nite Mare Extreme, mild, very little soot, 1920 to 2019 fps.5 shot 1/8" group @ 50yd., Totally unbelieveable.

3. 11.5 gr., 55gr.VNM., mild, clean, 2052 to 2103 fps. 5 shot 1" group @ 50 yd. @ flyers.

4. 11.5gr. %5gr. VNMX., mild, clean, 2032 to 2051 fps., 3 shot 1/4" group and 4 shot 1/2" at 50 yd.

5. 12gr. 55gr VNM mild, clean, 2124 to 2215 fps. 3 shot 5/8" group and a 3 shot 3/8" group @ 50 yd.

6. 12gr. 55gr VNMX., mild ,clean ,2064 to 2159 fps., 5 shot 3/4" group @ 50yd.


41.5 gr. Dp85, 55gr. VNMX., mild ,clean, 3533 to 3656fps. 4 shot 1/4" group, 5 shot 3/4" group. Errant 5th shot exhibited lead colored comet tail. looks close to max.


55gr. VNM., 36gr. DP74, RP cases, 215 primer, crimped in cannelure, clean 3599 to 3663 fps. 6 shot 1" group @ 50 yd.


52gr. FBHP Berger., 37.1gr. DP74, RP cases, 215 primers, oal=2.505", 3870 fps. POPPED primer, pulling bullets.


DP 74 That I have, again seems to be faster burning than the supplied data would indicate. It is suppose to be safe with 3% more powder than Accurate 2520. Might be the combination of components but I thought I'd pass on this info anyway.

The SR 7625 looks to be doing very well for reduced loading as does the Varmint Nite Mare Extremes. The comet tails at high velocity may prove to be a concern???? roger

Roge,

Good info.. looks like SR 7625 is a good powder to turn the old 22.250 into a 22 Mag...

About 10 grains or so, and the 22.250 would make a nifty squirrel hunting rifle....

at that velocity I also bet it would clean up the accuracy in a shot out 22.250 barrel...

I have a tube like that, I ought to put back on the Mauser it came off of, and see what I get!

thanks for the work up and thanks for the range report...
cheers

It'll be closer to a Hornet with 12 or 13 gr. Really not bad and cool barrel to boot. roger

Roger,

Good info.
I have a pound of 7625 left over from shotgun loading. I'll have to try some in my 22-250.
