Re: Idea! Official DTA SRS, HTI, Covert, Hunter Thread
It's been a few months since I visited the thread - in that time, I've received my DTA SRS w/6.5x47 conversion kit, shot it in one precision rifle match, and finished a 284 bbl on a 5R Bartlein DTA blank, and shot one match with that set-up. Awesome rifle, especially with the 284 bbl.
I'd gotten a solid 100yd zero for the 284 last week, then yesterday decided I had time to take the rifle apart to FDE CeraKote the 284 bbl & receiver (I'd balked at paying the extra $200 to have DTA CeraKote it) and the two magazine bodies I'd converted for the 284. Pulled the bbl., took the skins off the receiver, pulled the trigger assembly & scope base, got the whole thing coated, then put it all back together this morning after getting the parts out of the oven.
Conditions were about as close to perfect as possible this morning, so I took the SRS & the three 284 loads I've been shooting down to my 1000yd range, set up at 100, and checked zero again. I know these things are supposed to be pretty repeatable, but this was after complete disassembly, not just changing bbls. The POI was dead-nuts on, and with both H4831 loads using H162 AMaxes & Berger 180 Hybrids.
Moved on back to 600, entered atmospherics & velocities I'd just obtained from a CED M2, ran the data on Shooter & Applied Ballistics, put on the suggested 600yd come-ups, and fired quicky 3-shot groups with 162 AMax, JLK 168 VLD, & 180 Hybrid - all three were on for wind (probably because there wasn't any), and just a little high - .25 -.50 MOA.
Packed everything back up and moved back to 1000, running the numbers again on both programs, and fired four each of the JLK 168s & 180 Hybrids. Got four solid hits with each load, finishing with only 1/4 MOA of wind on the scope.
I gotta tell you, I like this rifle more each time I shoot it. And I'm not unhappy with Shooter & Applied Ballistics, either. At first, with the 6.5x47 bbl, I had trouble finding a good, accurate load, and was wondering what I'd spent all the $$$ for. But eventually, I found a combination with IMR4007SSC & Lapua 123s that hammers. When the Bartlien 5R came in, I had to jump right on that project, and it's been a shooter from the get-go. The SAC contour is considerably heavier than the OEM fluted bbls from DTA, but that's OK for a ctdg with the 284's recoil. I installed a TBAC brake/adaptor for the 30BA can that I got to fondle & drool over at my SOT's place the other day - the brake makes the rifle extremely comfortable to shoot off the bench or prone, so I can hardly wait to get the form 4 back & 30 BA mounted. Hard to imagine liking this rig any more than I already do, but if anything is capable of doing that, it'll be the TBAC can.
