I wanted to come back and update this. Keep in mind this a 22" barrel with a 1:10" twist, but here's what I experienced so far with the 117 American Whitetails:
- 1st two shots are always sub-MOA. But obviously I've had to shoot more than two rounds at a time because a) I was "breaking in" the barrel; and then b) moving on to trying to sight it in. At 25 yards the first two rounds go through the same hole, and at 50 they're touching.
- After the 2nd shot the groups start opening up, and after the 4th and 5th shots it's considerable, mostly stringing left and/or down.
- Given how freakin' hot it's been it may very well be that the barrel is hot (and perhaps I'm bit fatigued), though I've tried everything from putting an ice pack on the barrel for up to 5 minutes, or just generally letting it sit for up to 20 minutes.
So with that in mind it's occurred to me that this gun simply does not do well with these 117 grain bullets, so I've ordered some 100 Barnes TTX's and will try those. If I can get my hands on some 100 grain Core Lokts I may also try those too, but if anybody has any thoughts on the matter that may help me out I'm all ears.
