I am curious if anyone has tested the difference between the two H & IMR 4895's and what they have found for real world differences in the two. (velocity, temp stability, kernel size, fouling etc) I specifically may try to see what I see in straight 6BR with heavies and possibly a 223 with heavies but I'm curious to hear from others..

Each powder is going to show different velocities is two different size of cases because you have two different burn areas . Then if you use different bullets IE a Burger and a Hornady’s , again the powders will act differently.

Probably same preference of majority to go towards the extreme line in hodgdon powders.. Seems like most people favor that way anyway.. I like varget , h4350 and h1000. My daughter’s fast twist 22-250 shoots imr4350 w/80gr smk very well too though.. so many choices ...

I can't remember for sure since its been several years. I believe i was running 26grs varget or 25grs benchmark behind the 69smk but that was a factory PSS remy and somehow had a nice length throat in it where i could seat the bullets longer.. Seems to me like i shortened them up later to better fit an LTR remy and they popped a few primers.
