Cold Bore Shot, Barrel Length/Profile Effects questions

[4g64loser]

This is 15 shots with no cooling or breaks, about one shot every five to eight seconds. The only fifteen I fired today. Bipod and rear bag, just laid down on the concrete and sent them. No cold bore. Measurements are edge to edge. If you want to subtract, then you can take about .21 off as it's a .243 projectile but doesn't leave a .243 hole.

To answer the obvious question, the group is not centered because I dialed off. I'd destroy my point of aim if I shot "zeroed".

I shot this today with a warmed bore from a 100 YO No IV 22 BSA from prone with a sling/50yd target.
COuple of flyers and took a moment to settle in but what the hell my eyes aren't what they used to be either.
I was too chicken to make corrections for how i though they were printing till I saw some daylight pop through the target so I knew I was in the black at least.
Its hard enough single loading one of those old dogs, let alone making a sight corrections with an Enfield sling around your arm. This rifle has a pretty good barrel on it I think from a major barrel manufacturer during its production.

Damn good work.
