Got started patterning 200gr. Partitions for my 8x57JS today. Gonna need to adjust the scope before I go any further.
Here's what's weird, though.
I got some tight little groups, and some outrageous flyers.
I'm wondering if my barrel is too short to reliably stabilize the bullet? That strikes me as unlikely, especially since it's an heirloom rifle and I don't know the twist rate.
Here are the details:
19 inch barrel
New RP brass
Fed 210 primers
200 grain Nosler Partitions
One of these shows two of the three bullets in a group.
The other either shows all three bullets through the same jagged hole, or a tumbling bullet.
So two questions:
1) Does anybody know the twist rate on a pre-WWII mauser with the serial number in Arabic?
2) Can anyone read the first photo for what might be going on?
