DRT Terminal Shock Load Data

[SouthPaw]

What powders did you test besides 4831?

None, 4831sc shot plenty well so I rolled with it. I have RL23 and H1000 which would have been my next two to try had 4831sc not worked.

Anyone else dabble in the 22cm with 79 Terminal Shock?
Have a barrel inbound with the intent to only shoot the 79 here in CA.

I'll be shooting some groups with 41.5 gr 6.5 staball soon. Hit pressure at 42.5. Getting 3040 fps out of a new 16" barrel suppressed. I'll probably try 4831sc also though.

My plan, after season is over, is to try 4831sc (found 1# locally), Staball 6.5, RL17. I have a good supply of the two latter powders on hand. 18" barrel sitting on the work bench, 500pc of 79 DRT, alpha LRP brass.

I searched the thread but didn't see any reference to it, figured I'd ask and see if anybody is loading the 95gr DRT in a 6 ARC? I'm brand new and making plans to start the journey with the wife's bolt action 6 ARC as it's the rifle we have the least ammo for. I've also got the same cartridge in a gas gun as well. Figured I'd poke around and see if I can find somebody getting good results with them. Tough to search the forums for DRT because so many references from people using the term for animals that dropped at the shot.

This is the load I used this year: Tikka .223 w/ 22” barrel, 79gr DRT, 23.0 Varget, Starline brass, Federal 205, 2.260” OAL, 2655 fps.

I’ll likely experiment more with XBR as the Varget was a bit crunchy.

Pics are the entrance and exit on a buck shot at 250.

Getting 2720 fps out of my 18" tikka 223 (suppressed) with 23gr xbr and fed 205 in ADI brass. Only loaded 5 to check for pressure but will load up a bunch and shoot some groups. The 5 showed promise though at ~1.5".

 

[cubdriver84d]

23.0gr xbr load. Drops line up with the .395 g1 bc now. +.4 off base quick drop to 400 then +.5 at 500 and +.9 at 600.

@cubdriver84d what did you end up with loads on the 95 DRT in the 6 Creed? Did you find H4350 or RL16 worked better? Going to load up some and see how they compare to my LRX loads.

I ditched the 6 creed after last season. Looking back at my notes, I settled on 42.5gr H4350 with an mv of about 2950. I don't remember why I chose H4350 over RL16, but I think I was getting a little better mv with less pressure. Never got great groups -- best was 1.6ish".

@cubdriver84d thanks for the info. Anyone else out there shooting the 95 is 6CM?
