I have an opportunity to get some IMR 4955, but I really don't see a lot of Hide members singing its' praises. Many seem to be wanting to sell or exchange for other things of the shooting sort, so I thought I would ask for some opinions.
I shoot 6.5 CM, 300WM mostly. Touted as temperature friendly and 'environmentally' friendly. That last part is kind of a red flag for me. Thanks for your thoughts.

It should work for the Win Mag but my only experience with it was in the 6.5 PRC with light hunting monos.

    I haven’t tried 4955 but the 4451, 7977 snd 8133 in that series of powders have been excellent
    Maybe a bit slow for the 6.5 but usable and in the range for lighter bullets in 300Wm.

    10-4 on the 7977. Best powder I have found for our .25-06. Gets the 115 Bergers down the range with the best velocities I have obtained with that rifle and the groups stay tight.

    I just started using it in 6CM. Results are promising. Looks like case fill to the neck junction is 44-45 grains without a drop tube. I loaded 43gr and 44gr under a 115 DTAC; got 2950, 3040 fps respectively @ 82°F. No pressure signs.

    Did you shoot for grouping and how did they turn out? Thanks
    I'd be shooting 140g in the 6.5CM.
