I was trying to help the man out as to what tightened up my groups. My box of bullets were .276 other brands were .277 I dont know which is right. Now your probably going to say my caliper is off. It is not an issue of how fast the bullet is traveling. It is an issue of 2 in 1 out. My group was one ragged hole and was the last group and the highest velocity. Tomorrow is another day!
Do as I say do, not as I do!

I split a chapstick tube and shoved it between the stock and barrel at the tip of the forearm.
Looks like I'll be bedding in some pressure.

Rainy day group, windy day group. Half inch targets, think we'll call it good for now. FL bedded the channel to try to stiffen the forearm a bit, nipped mechanicals, added tip pressure. Whats the lastest with the OP?

Was this issue resolved?
Sorry if I missed something, just wondering whether the rifle is shooting now.

If I'm reading the original post right the flyer is always the third shot. If it was a bullet jacket issue wouldn't the flyer be less consistent (sometimes 1st shot, sometimes 2nd?). If it's always the third you'd have to be always picking that non-concentric bullet to fire as the third shot which seems pretty statistically far fetched

Could be trying too hard on the third shot letting the round warm in the hot chamber and causing a little extra juice throwing the bullet off its node.Quite common on a sportier weight barrel especially if you are in a small node or at the edge of a node. Never seen it happen with a three round group but that may be because I shoot five shot groups at least?
Just messin with you guys,its probabably the bedding

The OP`s question was interesting to me, thought I may learn something, as I`m having the same issues with the 7mm 168 LRAB`s. I`m shooting a 7 Wby,9 twist, 26 inch PAC-NOR and working with the Wby lead. Have tried various powders/primers/seating depths/cases/ neck trimming etc to no avail. Best 300 yrd groups are at 1MOA. I think these bullets should do better. Interestingly, the Berger 168 proved just as difficult to get to shoot, someone here suggersted 180 hybrids, these bullets shoot wery well, 1/2 MOA at 3, 4, and 5. In my rifle, I think I`m limited with both the twist, and the lead. Don`t remember reading what the OP`s rifle has. And no, it`s not the bedding...

Loaded some of these up and shot them today. Onlyn did three powder charges in half grain increments. Stock Kimber Monatana 300WM, and it was the 190gr 30cal version.
Two charges shot about 2MOA, whilst one shot .7MOA and was "2 in 1 out" , similar to the groups shot by the OP. My buddy ho gave me them to try had the same issue with the powder charges, and im curious if anyone else has seen this?
Obviously different powder charges will shoot differently, but ive never seen such a big differencd in group size. Now all ive left to do is tinker with my one good load and see if it can be improved.

My heavy barrel 338 EDGE tends to throw a flyer, sometimes, on shot #4 or 5, but I generally will fire 5 shots fairly rapidly. I'm using 250gr Accubonds @ 3000fps. I'm thinking the bbl might warm up a bit. Here in AK, much of my shooting is done at temps of 50* or cooler.

I experienced a similar problem over the last week as the op did. Funny thing is on my rifle the 3rd round was also always the flyer. I then removed bedding from below, sides and front of recoil lug. I also seated bullets slightly deeper and the rifle then grouped extremely well. Unfortunately I did not try one element at a time, but by changing the two elements I solved my problem.
