You mentioned a recepie, but have you actually done any load development to get to that? Maybe load a few groups per charge around that number, +/-.5 grain and see what works. Like, 43, 43.5, 44, 44.5, obviously watch out for pressure signs...
If you just loaded 44gr because someone told you too (also because there's no mention of load development in your post), that was a bit dangerous, you should always work up your load.

This you will need to explore with your own components. The powder is fine and there are a lot of people that would be using that powder and qty.

That's my fault, squeezed trigger at the top of my breathing. I knew I've stuffed that shot just as I pulled the trigger.

Thanks for clearing that up mate. in view of that, it could be that your "grouping problem" is more complicated than it appears at first glance and is comprised of two things:-
1) a crook rifle, for instance the loose screws
2) shooting technique: the lone shot above.
If you own a rimfire, practice your follow through. This skill degrades with each shot fired (sorry) and you have to be conscious of it before every shot. Recoil will spoil it; for instance you fired a crook shot with the mild 223 after the unsatisfactory 308 session. My guess is that a poor shooting habit followed you to the 223. that happens. It's some kind of memory thing. If you don't have a rimfire, try dry firing. Maybe get snap caps but always remember to follow through. You have to make a conscious effort

Houge overmold. I know people hate them but personally I like them a lot. It fits my hand better than my thumbi hole that I have on the 223.
Action screws are definitely tight. Scope is definitely tight.

Could be the problem - are u shooting off a bag or bipod.

Bipod, I don't like bag, rather the good ones are a bit dear for me.

Getting very good results with Hornady 168gn ZMAX projectiles in a HOWA .308 1in10 Varmint 20" barrel.
Just my load so caution as always...
ADI 2208 at 43.4 (and 43.5gn), WLRP, TL 2.008", OAL 2.800" give 1/3MOA groups regularly at 100and200m (bipod and bag)
Have shot the ZMAX at up to 700yards with local Long Range Club with more than OK results for a "hunting" projectile.
Other guys at range get super results from Howa .308 in 24" barrels with 44.2gn with 168gn ZMAX as a FYI
Generally pay $195-215/500
I know that's neither projectile or powder you've mentioned sorry.
Point being, every one I see shoot 168gn ZMAX in a Howa .308 1/10twist barrel gets good results.
