Anyone who did this ?
Very interesting. I would be interested to hear of anybody with experience of a .177 ST barrel, that does
group at 50m, sub 12 ft.lbs. I can't say I've read any positive confirmation of this nature.
I've long believed that between 40 and 50 yards is a kind of critical range for 12 ft.lbs .177, where a lot of barrel/pellet combinations will group exceptionally well below that range and start to open out above that range. We read similar stories for the Defiants a few years ago. Great for closer ranges and FAC, by some accounts not so good for FT at 55 yards.
There must be a PhD research project or two in this somewhere.
