So it seems as though a ballistic tip will work good, is a Hornady SST just a ballistic tip ? I have some 125 gr nodler partitions in factory loads also. Sounds like any of the bullets I have will work, maybe I should just see what is the most accurate and go with it
I am not sure that the SST is the same as a Ballistic Tip because years ago most of the users of the 7mm 120 BTs were pelt hunters and their only complaints were the explosive nature of the BT. Give that this was the largest market for the 120 BT, Nosler changed the jacket thickness
to minimize this issue. Problem solved. Being the non believer that I am
that Nosler had actually done this, I decided to compare the 120 to the 140 Ballistic Tip by sectioning each bullet like a metallurgy cross section specification. I found that Indeed they had thickened the jacket thickness by .010 thousandths over the 140 to compensate for the added velocity.
So the 120 Ballistic tip has a .010 thousandth thicker jacket and seems to be very predictable. I have not done a side by side comparison of the 120 BT and the 120 SST so I cant comment on the difference.
