I have used both back in my teens. Both were "explosive" shattering in the game, but the Silver-tip was the worse of the two.
I used them in 30 cals and 270. Not what I like in either.
In the old 30-30 the 170 Gr Silver-tip did ok, and it also seemed to do fine with the 300 grain 375H&H, but I only killed 2 deer with the 170 gr silver-tips from my 30-30, and one large Idaho Elk with the 375, so my experience with those 2 bullets was very limited. Other reading this may have more info. Please chime in if you do.
I saw predictably bad results from the 130 gr 270 S.T. and the 150 and 180 gr ST from 30-06.
I killed about 6 deer with the 270 and the 130 Gr ST and about the same number of deer with the 30-06 with both 150 and 180 grain ST bullets. No good to say about them, other than they were quite accurate. In my old Winchester 270 the 130 gr STs were some of the most accurate bullet I ever shot.
The Bronze Points I used were also in 270 and 30-06. They came apart badly too, but not as violently as the S.Ts.
Both bullets were thinly jacketed and the tips are basically just "wind-screens"
