Nice work
I have been playing with the Berger 230s in the 300 Whisper/BLK for a while now and might have finally settled on a load.
Pointed and HbN coated Berger Hybrid 230 HPBT
Lapua 300 BLK Brass
Federal Primer
Vhit N-110, 9.4 gns
Loaded OAL 2.393, my comparator length of 1.695
I played with seating depth a lot to try and tighten up accuracy and the ES/SD. Everything from twenty thou jammed to twenty off the lands in .005 increments.
Center to center was well under 3/4 inch with vertical spread being about 0.6 inches at 100 yards. That's a 3/4 black paster.
Average velocity of 1077 with a high of 1085 and a low of 1074.

Rifle
Bighorn TL-3 Action
Bartlien 1-8, 16.1 inches
300 Hush reamer, made by PTG in 2008
Accuracy International AX Chassis
Schmidt & Bender 5-25
Thunderbeast 338 Ultra
I am sure I could get it quieter if I switched powders, but my accuracy is excellent and the ES/SD is so low with N-110, I am tempted to just stop experimenting and go with it. The running of the bolt makes as much noise as the gun going off. 25 yards away you cant even tell it went off.
Here is the video of it. Shooting at a 6x6 plate at 300 yards. Camera set up almost like a sound meter would be for a no-shit test.

That.... is impressive.
Loaded up a bunch of 6CM ammo with H-1000 and 115 gn DTACs.
One of my 6CM barrels is still holding 3/4 MOA with the exact same load I started out with over 4,000 rounds later. I think this is a Bartlien or Kreiger barrel. The inside of the barrel looks horrible and the velocity is down a touch.
I still have a couple thousand more of the old DTACs before I get into the new ones.
I also wrapped up hydraulic forming of 500 pcs of 223 brass into 223 Ackley. Tumbled it clean, bumped the neck and then annealed it. Now its ready to hand off to my niece so she can get back to shooting.
200 140gr BTHP's 6.5C, and 100 123 AMAX's single stage .
loaded 100 17 hornet, 100 17 fireball, and 50 17 Remington. Ready for more prairie dogs.
500 rds Sierra 77gr 223 23.3 CFE 223
500rds hornady 55 gr SP 23.5 Xterminator
Now I'm in the middle of detail cleaning the 1050 it's been a while.
Sold one of my dillon's.
Matt I hope.Quote:
