Well, what do you think about this bullet @ about 2600 fps?
I scored a s**tload of thes for real cheap,and would like to use them.
Probly nothing bigger than Texas whitetail,and feral hogs.
Thanks,
Mike

Mike, 175 gr.'s in a 7x57 will kill anything in Texas. I shoot the S&B 173 gr. loads in mine and over the past couple of years it has accounted for pigs, Dall sheep, Axis, Sika and Whitetail. I get about 2470 FPS with the factory loads and they have really worked well for me. I'm currently working on loads with the 154 gr. Hornady, up to 47 grains of RE15 and this is looking like a good load also.

Mike, I used this bullet in my 7X57's loaded to about 2720 FPS with 54 grains of N205-now gone, alas!! I shot several deer in/around the Fort Hood (Killeen) area, and found that it went right through them, regardless of range, and did not destroy a lot of meat. Had one doe go about 30 yards after being shot behing the shoulder with one - at a range of about 20 yards! If I recall correctly, she went farther than any other deer shot with this bullet. These are tough bullets, and launched between 2600-2700 FPS, retain close to 1000 foot-pounds at 1000 yards from a 7X57mm Mauser cartridge!!

I've always been a proponent of heavy-for-caliber bullets vs the light-and-fast obsession. I'd bet the 175gr in that 7mm will give you excellent service and maximize it's big-game capabilities. Assuming it's of sturdy construction you'll get fantastic penetration with the high sectional density of that bullet. Some Sierra bullets are known to be a little too lightly constructed, but in reality with the animals you mention as your primary targets, this should not be an issue.
