Hi again Rob44
I only noticed the destabization this last time. The first time it was so windy I thought the target was just blowing around. I wrote to Woodleigh and this is part of the response:
There may be some pressure difference between the two bullets, but you are probably right about the short barrel not stabilizing the PP properly. The rn is
1.250” long, where as the pp is
1.381”, a considerable difference. The 160 pp stabilizes in most standard 6.5 x 55 and military rifles, but they generally have a longer barrel than your’s.
So, maybe several factors conspiring to challenge me!
