No. 5 Accuracy

[villiers]

I think the `wandering zero´ people mean that accuracy diminishes when the barrel heats up. So you´d need more than ten rounds.

To me "wandering zero" would seem to suggest successive groups with changing "POI" not simply increasing dispersion. And since the barrel is fully floating (forward of the reinforce bearing) why would simply heating it up change anything? My rifle (with restored original bedding but using Remington FMJ) doesn't seem to be affected by 30-40 fairly quick shots while that in an earlier post in this thread (Parashooter using Mk VII) does.

I apologize for any confusion caused by my post. To me, the placement of shots 26-30 in the same ~4" group as shots 1-10 demonstrated that my No.5 did not show any significant change in POI after 25 quick shots. (Shots 11-25 were fired with a different load at the lower target - just trying to conserve good Mk7 by heating up the rifle with cheap handloads.)

100 yards

Upper target: shots 1-10 and 26-30, Mk7, X=POA (6:00 hold)
Lower target: shots 11-25, handloads, 6:00 hold.

Parashooter- My mistake. There appeared to be two distinct "clusters" in your MKVII target and I assumed the final 5 shots were the smaller grouping to the left and slightly down.

I know the ten targets wouldn't be "discussing" my accuracy, by then I can let'er cool of and reload for the next ten lucky buggers who wish to have a word about the 303 round.
