The bbl length on my 8x57jrs is 23-1/2" long, and i drive 200 grain Nosler partitions over 2,500 fps in my drilling. This load shoots plenty flat for 2 to 300 yard shots, and has a lot of penetration and killing power when it gets there!
I tried other bullet weights, but i was looking for a "one gun load" that would work on everything. I think i found it, as i've taken everything from coyotes, blk. bear to moose with this load.
This last fall i took two whitetails with this load, a 9 point and the 8 point in the picture. The longest shot i've taken so far was at the 9 point, and it was 200 yards away.
A "honest" 200 yards is a long shot on any game animial, but if you practice at longer ranges than that, the 8x57 will still do just fine.
