    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.
