Nice kit and excellent results.
My rifle was set up primarily for deer stalking, pre moderator time.
I used Nosler 150bt and the 155 smk/scenars.With the slowest barrel twist it gave faster velocity and a Swarovski PV 6-24×50.
Heavy bullets are better for the longer range. Keep up the good work.

2 moa at 100 yds is a 2'' group , are you hoping to hunt mice because anything you shoot at 100yds from a rabbit to a fox will be bigger than 2'' ?

most 270 shooters are happy with a 4'' group !

My go to gun is a 6.5-284 which shoots ⅓ MOA on a bad day so going from that to 2 inch group was a big suprise 🤣
 
If the speed you are after than 155gr. I use Scenar L for this and max load of Viht N150 gets me just over 3000fps out of 26" barrel.
I get more consistent results with 167gr Scenar and 168gr MatckKigs.
I only shoot up to 600 yards
 
I have a 26” barrel on my AX .308. The best weight I’ve settled on is 175 Ballistic Tipped SMK. Accuracy at over 1000 yards is easily and routinely achievable. I got a batch of Target Master Match ammunition from HPS which has proven excellent.

They will be great. For target and deer. Similar to the old A max. I used N140 for mine but N150 would be better for your 24in barrel if you are using vhit powders

Just tested - N150+Eld-M 168gr and got 0,4moa group. Promising load, now i need to fine tune bullet seating deep.
 
I've eventually got round to doing a load as follows,

24inch 10-twist barrel

43 grain N140
CCI 200 primers
168 grain ELD-M
Lapua brass

Velocity averaged at 2612fps with an SD of 8.7

Accuracy was great, about ⅓MOA at 100 yards, although disappointed about speed, haven't had chance to test it any further at the moment

Well done. That's an excellent load. You've achieved superb accuracy combined with moderate velocity which is a mutually beneficial situation as the docility of the load facilitates low recoil and thus better shooting, less wear and tear on the rifle/optics, less fatigue etc. You're winning on every level.
 
I have had great luck with the Berger 185 gr Juggernaut for long range shooting. Varget and PowerPro 2000 work well for me. For deer, I use 165 gr bullets.

This bullet has an average G7 BC of 0.261 (Bryan Litz from actual testing). At 1K, its retained speed is calculated to be 1,174 fps (but that will vary considerably shot-to-shot either side in practice). That's at sea level, 29.92-inches Hg / 1,013 millibars atmospheric pressure and 59-deg F air temperature ('standard ballistics conditions'). Although still barely supersonic, it's rather too close to that boundary for good results and is smack in the worst of the turbulent trans-sonic speed zone. In such conditions, there are considerable stability differences between designs / shapes of bullets unrelated to the BC - some models do reasonably well; some don't, but I don't know where this ELD-M fits in. What is likely is that if shooting on a range using sound-locating e-targets (Silver Mountain or the ShotMarkers used at Diggle) the target will fail to record some of your shots at this distance.

The best all round 308 Match bullet for this kind of rifle at 1,000 is as @3IDV says in the previous post the 185gn Berger BT 'Juggernaut'. Sadly, they are as rare as hens' teeth in the shops such is the demand and like all 308 Bergers cost over £1 each these days. A cheaper alternative which you might actually find in stock and which has proven long-distance performance is the old and once-loved 190gn Sierra MatchKing, but you have to use pretty stiff loads with Viht N150 or N550.

I haven't had good luck with the 168gr bullets - they do great to 800 yards but then run out of gas (petro) after that. I'd vote for the 175-178gr bullets

You're thinking of the first generation of 30-cal 168s, the Sierra MatchKing and its similar form Hornady, Nosler and Speer competitors. They were designed as high accuracy short-range bullets. (In fact, the original of the breed and still arguably the best, the 168 SMK, was introduced way back in 1966 as the 'Sierra International' specifically for international 300-metre rifle competition when 308 Win was the cartridge for the ISU discipline.) It has a 13-degree boat-tail angle which while good at short distance is poison at long ranges when the bullet goes trans-sonic at 1.2 Mach and below. It then produces violent air turbulence around the back-end of the bullet body that at best produces much increased drag, at worst entirely destabilises the bullet. Hence, long-range US Service Rifle competitors regularly getting keyholing shots on the target from M14s/M1As back in their day. At 308 Win MVs, the 168 SMK goes trans-sonic beyond 800 hence its performance falling off a cliff.

There are several modern 168s that don't have this issue including the 168gn ELD-M. For years, my favourite 308 bullet in FTR was the 168gn Berger Hybrid which won me a few medals in high-level long-range competition.

Specifically the Hornady Amax in 168gr
Admittedly I have not experimented with much in the 168 line because I just want to shoot the 175-178gr boolits
