I recently got this mold
In the photo below, you see a trio of bullets- the HVTH is on the right. Long bearing surface, small lube grooves, meplat slightly larger than the XCB- bullet (in the middle). HVTH is an acronym for High Velocity, Target, Hunting.
I have a 4 cavity mold, that works very well. I have shot the bullets a couple of times, I started with water quenched bullets BHN27, and Viht N-110 powder; pan lubed with 666-1, tumble lube top coat; 19 grs worked well in my Howa .308. 27 grs Vectan TU-3000 also worked well with these conventionally lubed bullets.
I shoot from prone position at 100m. Front support on a bag. Rear support on an old gym sock filled with rice (really should get a better rear bag). The circles on the target monitor represent 1 MOA increments. With this set-up, my shooting skills and experience level with cast bullets (intermediate-ish), I consider 5- shot 100m groups better than 2 MOA «good», 1,5 MOA «very good» and sub-1,5MOA makes my day. Sub-MOA- groups I consider a fluke, until proven otherwise (still waiting for consistent sub- MOA load).
Today, I tried powder coated bullets, BHN 14. Intermediate loads with Tu-3000 gave disappointing results (3 MOA). However, jacketed-level starting loads with Tu-5000 (quite similar to IMR4064) were interesting. I shot groups from 36- 38 grs. The hottest load gave 4 hits really close together, and one flier (un-called, but might be me anyway.... dont know). Will shoot this load some more, and try to push it a bit further.
Powder coating is still a bit fresh territory for me, but I must say it is a facinating tool to have in the box.
