I still shoot the 7mm 130g spt bt in a 7/08, 42g of IMR 4895 with Rem 9 1/2 in a Rem case is wicked accurate and kills good to 350 that I have shot white tails...puts a lot of shock on a deer.
Killed a lot of antelope with the 243 and 85g sptbt in a 243. I think that this is a MUCH better bullet on antelope and deer than the 85g sierra BTHP(which I have shot thousands of).
30/06- 165g sptbt with a hot load of IMR 4350 is wicked on deer on how much shock it puts on a deer.
In my last Rem 700 in 25/06, a near max load of R#19, win primer, win brass, 100g Speer btsp could shoot small birds at 300 yards with my Burris 6x24 scope. This is a fantastic deer and antelope combo.
I used to make my own bullets for shooting benchrest competition. I had just made the decision to quit shooting Benchrest comp matches.
A friend was at the range shooting with me one day, and I saw his very tiny groups with a custom rem 700 with a Hart 14T in 223. I tried the 22 caliber 50g tnt and the 70g tnt and was simply astounded at the accuracy in my 22 & 6 PPC.
I sold the bullet making equipment the next month due to the EXTREME accuracy of these tnt bullet.
