Re: IMR-4350 temp sensitive???
I burned more IMR powder than any other brand. I found IMR to be very stable and less temp sensitives. IMR 4350 is my powder of choice for my 243 Winchester, 6MM Remington and 338 Win Mag, 4895 for my 3030, 3031 for my 35 Remington TC, 4831 for my 280 Remington and IMR 7828 for my 300 Win Mag. Live in California and temperature here varies from 40 degrees in winter to over 100 in the summer months.I buy 8 pounder at a time though, to avoid wasteful and tedious re-working of load everytime you purchased a pound can with a different lot number. Just like any powder, IMR is not immune to lot to lot variances.
To achieve the maximum possible accuracy, all variables must be remove or at least minimize.
