No luck with the hogs, but the small buck I shot had a complete pass through with a 1.5" exit wound. The shot hit the rib cage jellied the lungs and broke a rib on exit. Bullet not recovered. I've shot about 80 throu my Gren and had no feed problems and the tips did not show signs of damage when I ejected rounds after the hunts. I liked the accuracy and they seem to work fine on whitetails.

C.O.L.? What COL are you using for the Sierra Pro-Hunter? The profile is different than the Nolser BT so the SPH looks like it need to be seated deeper. AA's ammo w/NBT C.O.L. is 2.246. I loaded a SPH at 2.246 and it was into the lands. Would this create excessive pressure? Elsewhere I've seen 2.235 and 2.224 C.O.L.

Range report using Sierra 120 Pro-Hunter and Varget.
Lapua brass, Rem 7-1/2 primers, C.O.L. 2.226, 100 yds. 5-shot groups. 80degrees, winds 5-10 mph left to right.
28.3 - 1.186"
28.8 - .983" (Hornady's recommended max load for 120, 123 gr. bullets)
29.3 - 1.627"
29.8 - 1.344"
30.3 - 1.329"
Looks like 28.8 grs of Varget with the SPH could be an excellent deer load(at least in my Grendel). Not bad but want to improve. Tac has been highly recommended but I have some 4064 that is close to TACs burn rate. Any reason not to try 4064?

RR and Whelenon,
Good advice. The 4064 could be a whole different animal even if similar in burn rates. I've also been thinking about my loads and have decided to back off from what the old site data said (30.5 g Varget max) due to what Whelenon found as Hornady's max for 120 gn bullets (28.8 g Varget max). I didn't have that piece of info before, and would prefer to stick with a manufacturer's specs than to old thread data without any details. I didn't see any immediate signs of over-pressure with the 30.5 g Varget loads, but I really don't want to push it. With the new piece of data, it just makes sense to drop down to the 28.5 - 28.8 g range. The difference in group size from the old site max and the manufacturer's max wasn't much and is definitely within the range of operator (me) error. The 28.5 to 28.8 g Varget load will be good enough for the 200-300 yd ranges I was planning on. I'll provide details on group sizes after getting out to the longer-distance ranges. Thanks.

I just posted on your other thread. A little confusion on which bullet we're talking about. I checked Seirra's website, the only Game King listed for the 6.5 is 140gr. and the Pro-Hunter listed a 120gr. SPT. I'm assuming were talking about the Seirra Pro-Hunter 120gr. SPT.
