I have yet to fling a 175 NPT at game,but after a lot of use of the 160 NPT in 7 Rem Mags,I am going to make the 7mm Mashburn a "one load for everything" rifle,and the bullet will be a 175 NPT.
I can start the 160 gr 100 fps or so faster, but have noticed they both land the same place out to 600 yards,with the 175 started at 3075....so it gets the nod far as I'm concerned...
Pals who have used it here and in Africa for a good bunch of plains game tell me the 175 Partition a wicked killer on everything started that fast,and two of them also say(after years of 300 Weatherby use),that the 175's started over 3000 fps kills just as well as the 300 with 180's.
I hate looking at ballistic tables, but a glance at the Nosler tables shows the 175 Partition started at 3000-3100 as hanging pretty good to 600 with a a 180 gr 30 cal started at 3200 fps.
I hope to find out,since I have used the 300's myself a good deal.
