I've tried the 100gr. and 120gr. Partitions in my M77 Bob. The 100's are showing some promise seated closer to the lands and running hotter. The 120's I'm about to give up on. Nothing I've done with those is showing any promise. Of course I'm pretty much coming to the conclusion that my rifle likes nothing better than 100gr. TSX and 46gr. of H4350. I consistently get those into .625-.75" groups. Nothing else gets under 1".
If your rifle will shoot either the 115 or 120, pick one and move forward. Either will do a tremendous job at least up through mule deer and I wouldn't be afraid to use them on elk. As for me, I'm stick with the 100gr. TSX. They're about 10 cents each more expensive which realistically isn't much. And they just plain work. Most importantly, my rifle loves 'em.
More choices, the American Way. At least until the Obamanation has his way with Lady Liberty. God help us all.
