Certainly want to start loading for it after my two years is up in Germany. Chrono'd three Nosler factory loads at the range with Hawk_Driver. Was only 34 degrees with a PA of about 60 feet. Have read velocity slows between 2.5 - 4 fps per 1.8 degrees so that factors in.
...............Claimed.....Actual avg.....spread..... diff 140 ABs........3150........2983............49.........-167 150 LRABs.....2930........2904............10.........-26 160 NPs........2950........2736............31.........-214
I would expect a difference with the cold temps, but a 214fps difference? Claimed looks real for the LRABs

Don't speculate when you don't know, and don't second guess when you do.

Great looking rig. You are going to love the 280 A.I. especially in that rifle.

So did some shooting today, tried different ammo, played with the scope, and don't know whats up with these flyers. Group on the left is off a bipod measured 9/16" (not including flyer). Group on right without bipod, off bags, went 5/8". About the same really. Had another group touching, also with a flyer - and didn't clean between groups. Am I just [bleep] it up? Both Nosler 150 ABLR ammo Next week trying some handloads

Your rifle may not like that ammo.
Could also be the bipod. With a stiff stock I use a soft rest (bags with cloth diapers folded over them).
Could be the scope, due to parrelax. Could be your cheek weld, or sight picture.
Or wind gusts.
If those were handloads I would suggest adjusting seating depth and purchasing a concentricity gauge.

Flyer typically seems to be the second shot

It could just be some inconsistency in the factory fodder possibly.

Shoot a nine shot group, one three shot group at a time, all at the same POA. That will likely give you a better idea of what the load is doing.

Loading up some 150 TTSXs and 160 ABs tonight, but will keep playing with the factory stuff as well. Might just try the 9 shots to see. Thanks

Accubonds were under an inch, but not impressive at .866" and .706" with IMR 4831 and 4350. Really wish I had more of the TTSXs to try out, but just went with three of each to get a general idea. After shooting earlier to check velocity we loaded up 56.5 grains of IMR4350. First 3-shot was .05 off, went .307". Second was .1 off and I pulled one. The other two were .156". Loaded up nine more of each and can try them next time. All were running in the 2960ish range

First time shooting it in 18 months. Here is the first group then I tried a similar load with different seating depth that went to crap. Then weather went bad. Happy with that first one at least. Same load as the one on the left in the other photo

Keep getting tempted to switch the scope and stock due to the rifles potential, but keep telling myself it is for hunting and not groups.

So were you high, shooting to the left or right? I see in the other targets, you are also not zeroed. Do you have any target pics where you are zeroed in? Very nice rifle though. "18 months" later and I expect the damn thing to finally be zeroed in...
I try to stick with the basics, they do so well. Nothing fancy mind you, just plain jane will get it done with style. You want to see an animal drop right now? Shoot him in the ear hole. BSA MAGA

That's what happens when you get a new rifle, a few rounds loaded, then sent out of the country for a year and a half without being able to settle on a round or even think about zeroing it till you choose a load. But 1.5" high I'll take. One click left, should be good if I stick with that load.
