Does this effect accuracy by changing barrel harmonics?

I have attached the V3 bayonet to many rifles over that past year of load development and testing and have found the following. I have personally run it on a .223 with a varmint profile, both suppressed and unsuppressed and found no impact shift with this barrel in either configuration. I have also run it on several sporter profile barrels including 7mmRSAUM, 300 RSAUM, 300 RUM, and 30-06. With these rifles I have found the impact shift to be so minor that I was still able to mark under 1MOA, 3 shot, 100yrd groups with all but the 300 RUM, with that rifle the best I could shoot was just at 1MOA. I reconfirmed shots again without the bayonet on all rifles tested and found the position of the hits moved a little but the size of the groups were still about the same as with the bayonet. All of the rifles I've tested have been completely free floated and were shot using a bipod and rear bag during testing. The V3 bayonet only weighs 7.8oz with the all of the spacers needed for use on a sporter barrel so I don't think you should see enough change in impact to warrant not buying one.

When recording shot strings, can you return to a saved string and add shots to it after moving to a difftent string?

I am pretty sure that once you have archived a shot string, you can't save additional shots to that string. However on the V3 you can open the archived data in a spreadsheet and manipulate the data there - for example merge two shot strings to determine the Extreme Spread and Standard Deviation.

I know the 1/4" bar is supplied so the projectile doesn't hit the arm, but how far away from the bore line will it read accurate velocities?

I have used it as far out on the barrel as I could position it with fine accuracy. That is about 4 or 5 inches. The reason I positioned it that far from the muzzle was because a huge muzzle brake on a 338 Lapua Mag. it wasn't possible to mount it any closer. This chrono makes everything else obsolete.
