Great results for me with Alliant RL10X and Federal 205M primers, WW brass in my Cooper M21. Assuming 204R, of course.

yes 204R should have put that down

+ 1 on the Reloder 10X. I've also had good luck using CFE223 with 39 gr BKs. (my favorite bullet)

No worries, magnum. I figured it was a 204R since you posted under "204 reloading". Just did not want to mess you up if by chance it was a different cartridge .

scope and everything tight ? twist rate ? barrel clean ?

Great results for me with Alliant RL10X and Federal 205M primers, WW brass with 39SBK's and 40 Grain v-Max. .2's are the norm. Thats with a 1/11 twist barrel.

Do you have a moderator on your rifle?

Magnum - If the 32s and 40s both work great, then why bother with the 39? You might be wasting time, $$ and barrel life.

magnum--My old Savage 12VLP in .204 Ruger and the 26" factory barrel shoot pretty small groups using 28.0 gr. of H4895, WW brass and Remington 7½ primers.

You don't mention that you tried altering your seating depth. I'd suggest trying a few different seating depths before I abandoned the 39 gr. Sierras. They seem to work great in just about everyone's .204 Rugers.

Reloder 10X, as some mentioned, works pretty good for some folks.

I think because the 39 SBK's are ballisticly the best bullet to use as the have the highest BC over any 32's or 40's.

yes everything tight, 1in12, barrel put 10 rounds down it of 32 nosler it was cleaned just before this and shoot allmost hole on hole then went on to 39 bk and all over the place went back to 32 nosler and back to hole on hole ( i just think my gun dosn,t like them ) but the 40 grain vmax shoot very well it just seems to be 39 bk and my gun

Try it with mod off, just shoot for groups. I have seen stranger things happen.

That is a pretty big jump between 27 and 28.2 in a 204. I didn't see where you mentioned what brass you were shooting. Before you give up on the H4895, you might want to try between 27 and 28 going .2g at the time. There is a very good chance you jumped your accuracy node in that range. I'm assuming you were using H4895 with the 32's and 40's which shot lights out, is that correct?
