I bought a Rem. 700 Classic this past spring in this chambering. The rifle has a 24 inch barrel,... In particular, with 150 grn bullets, using TAC powder, reaching close to 3k and with 4064 and 180`s, close to 2900 fps. None of the usual high pressure indicators present in either load.
Comments or added results?
I also have a Rem 700 Classic in 8x57JS. A 180 gr at 2900 fps seems a little hot to me. I haven't done any load development with bullets lighter than 195 grs, though. I use the following table as a guideline when working up loads as to about what velocities can reasonably be expected with various bullet weights in the 8x57.
I chronographed some of the S&B 196 gr SPCE factory ammo from my rifle and the instrumental average velocity was 2647 fps. (Factory spec is 2592 fps as shown in the table.) Extreme spread was 31 fps with a stand deviation of 10 fps.
Back in 2005, I used a 220 gr Woodleigh RN in my 8x57 at 2400 fps (chrono average 2402) on a couple of Warthog and Impala in South Africa. It worked like a charm. I did most of my hunting with my CZ 550 in 9.3x62 on that trip but took along my Rem 700 in 8x57 as a backup rifle.
Warthog - Rem 700 Classic in 8x57
The 220 gr Woodleigh RN at 2400 fps knocks the snot out of Warthogs!
(He went about 10 yards after my shot and this is the position we found him in.)
