Thank youI've used H335 with 55gr, never ~75gr, but I'll echo the two things that others have said:
-I find it extremely hard to believe that you could go from fine at 22gr to grenade at 22.7gr, especially in a bolt action rifle.
-The "known H335" on the left does actually look like H335. The other two do not.
I don't know if you said this was possible or not, but when I switch powders in a thrower, I dump all of it out first of course, and then look into the very bottom with a strong flashlight. If I see any remaining granuals sticking to the sides due to static or whatever, I flush the whole thing out with water and let it dry. I want ZERO chance of mixing any powder in the hopper, of course and especially if switching from pistol to rifle.
I used the hogdon chart from the Internet for 75gr
My rifle powder thrower has only seen varget and now...h335
I have not loaded pistol in over a year and those are set up...I'll end a picture
