You might consider getting a nice free float handguard to get some more accuracy from that rig, I wouldn't want a nice Krieger hamstrung by a 1986 handguard!

It is a national match free floated tube. The only reason I may get a Qual rail is to attach a bipod to later.
Not at all, I don't hunt out of a blind at night, I'm standing, with my rifle mounted on a tripod.

I do a lot of hiking and usually shoot seated from stix. Only thing I would change is bring the barrel down to 20".

What type of ballistics are you guys getting out of these setups? Curious about your scope height, zero distance, rise before zero, drop after zero, etc.

I zero at 100 yards but usually dial up to 200 yards on the stand. That way I'm good to 280 without any holdover. The rare shot opportunity past that usually allows time to laser it. My 6DTI was purpose built as a sub-300 yard calling rifle and I like to call them in close.
Here's a chart with 100 yard zero, 6DTO 55gr NBT-LF @ 3560 fps (DA 1500).

I've been rocking an DPMS LR243 Ar-10 for 16 years that has killed hundreds & hundreds of coyotes, it's basically stock minus the ambi charging handle and the ELFtmann trigger.
For the last 5 years my thermal setup is an AR-15 chambered in .224 valkryie that i couldn't be happier with.

Go for it, Erich, you'll love it. My all time favorite was a Dtech 243 WSSM w/3.5# Timney trigger, 4.5-14 Burris FFII. Mike and I talked several times as to choice of caliber; I was leaning toward the 25. It shot the 87 gr. Hornady BTHP load Mike recommended into little bitty groups. Used it for coyotes, hogs and culled some whitetail does with that load. Worked up a load w/100 gr NP's for deer, but after shooting several hogs & deer with the 87 gr. while coyote hunting, decided It was not necessary. Not particularly fur friendly, but that's not an issue in S. TX.
18" 1:10 300 BO, 640 Rattler, Kaw Valley comp. shooting 135 FTX or 110 vmax. For 100 yrd shots. 2 hogs and an armadillo so far. EDIT: changed the handguard out for a long one. Was resting the barrel on the stand window to shoot - not a good idea. Missed some shots.

Carbine, check your PMs.
Off the cuff I don't remember but I'm point and shoot to almost 300.

You bought barrel straight off the Sharps website ? . What length did you go with ? Pic. looks like 20"
70 grn Blitzkings should do well . The barrels I have,both favored the Sierra's for the tightest groups . The Speer 87 grn. tnt's group well also but run 100 fps vel. slower .
What I found that was Really Weird, and I tried several different loads . I could never get the 75 Vmax's to group worth a shit from either barrel . I have NEVER had a barrel in my life that the Vmax's would not do at least MOA .

Yessir src 20. That is strange, typically the vmax is the default because they seem to group well every time.

I really interested in hearing what your Vel. #'s are going to be on that 20" barrel . I really been thinking of sacrificing short-length comfort, and going for longer length to increase performance speed.
Vmax's Always, it is for the most part my goto Varm. bullet of choice . 'possible ?' maybe I just got a bad lot# on those .25 cal vmax's . but I have never had a problem with any other vmax's from .22 / 6mm / .30 / that I shoot .
I got NO complaints, The barrels shoot good that sharps uses . The barrels I got from sharps are different. they changed twist . the older one is a 9-1, and the newer one is a 10-1. 3-land poly bore .

You need to post-up that Garmin Pic. you PM'ed me. With the Vel. out that 22-inch barrel .
-
I Was at the 100 yrd. Bench 4+ hr. today with a few loads and a chrony. for the .25x45/ sharps . 16"inch Barrel Length 1-10 twist / AR 15 / #'s off Garmin Chrony. ,with a new 500 pack of Sierra 70 grn. blitzkings .
------
A-2200 is 'definitely' for SPEED in the lightweight Sierra 70 grn. blitzkings . I did two loads I knew were going to pretty Warm, and they were. It will give the blazing speed with the 70 bk's, but you will pay with Abusing the primer pockets and 'very' short brass life.
26.5 grn. A-2200 was Vel. average @ 2988 fps / primers were 'really' Flat . Promising groups sizes. there is a good accurate node somewhere under this charge weight .
27.0 grn. A-2200 was Vel. average @ 3042 fps / really flat Primers, with a little case head brass flow on bolt face . pretty Hot Load and 'crappy' group sizes. BUT.. 3000+ fps Vel. out the shorter 16" barrel in a .25 Cal. just friggin Amazed the hell out of me.
------
A-2230 / X-terminator is slower than the A-2200, but a lot kinder to your primers and pockets . I use and really like 2230/X-terminator for the heavier 87 grn.TNT's. So I did one up with the Sierra 70 blitzkings .
( 28.5 grn.) A-2230 was Vel. average of 2881 fps. and grouping good also . Primers were flat with just a slight round edge. and 2880+ vel. out a 16 inch barrel length using 70's is still pretty respectable. So this is the charge weight I am going to work around for the sierra 70 BK's
Also for Load reference . when using A-2230 and Speer 87 grn. tnt's . ( 27.0 grn.) gives ( 2617 fps ) out a 16 inch barrel . Primers are still sitting little proud with round edge.
( me ) .. using the 16" barrel . I have loaded up @ 27.8 grn, 2230 with the 87 tnt's . Good groups and just sounds like a Sledge Hammer hitting the dogs.

Agreed its all about the dwell time. I’m not a fan of an adjustable gas block. I’d much rather tune via buffer spring and buffer weight for a smoother recoil impulse. I’m also a major advocate for flow through suppressors, and the way lantac bcgs vent the gas. Times I’ve built with an adjustable block I’ve had to run it 100% open it’s like putting a bandaid on a problem. In my opinion.
