Imr 4955 & 4451

[SHR970]

Has anyone tried these? I'm trying to get some here for 6.5x55 but a long wait. Just thought if you guys found them no good it may save me a lot of time & order something else. Thanks guys.

970, I've tried both. Looking at a burn rate chart the 4451 has a burn rate very close to H4350 and 4955 is close to H4831. A friend is using the 4451 in a 30-06 with great accuracy.

Nice one, I'm leaning toward the 4955 for my 6.5x55SE only as it has 260 on the bottle neither show 6.5 but burn speeds seem suited for it.

I just picked some up today at a local store, how well did the 4955 perform? Im planning to try it in my 7mm rem mag with 168 bergers. For my next build i would like to use the same powder for a 284 win using the same powder. How did it do with temp stability?

The best info I can give you is that my 22" 260 Rem delivers 3032 fps with the Badlands 125 gr mono & 47.5 grs of Rel 26. Considering the greater capacity of the 6.5x55 I see Rel 26 as a prime powder for any bullet of 125 gr or heavier in your 6.5.
