TakeEm I was not offended.
...just commenting that I have not had it happen. You know what you saw and maybe it was the RL22,or maybe it was something else. Dunno.
Temp variation with powders is such an old issue to me because I have been watching it for many years with offenders like IMR4350 and IMR4831;I don't doubt it goes on with RL22,but it happens with other powders as well.
It does not get real cold here, but I shoot all winter in temps to 0F and at least to 300-400 yards RL22 does as well as anything else.
Recently I had a 270 Winchester change POI with H4831 that had stayed zeroed for about 4-5 years; I think it was due to a change in powder lots......a shift in components will do it as well....so won't a squirrelly erector assembly or range conditions.
