204 for accuracy

I have a 204r shooting 8208 and 39sbk. It’s a cz 527 with a pac nor barrel. I took charges up to 28.1 pushing 3998fps.
I settled on load of 26.9 as I felt that one gave me best group. Had another at the upper end but don’t need to run it that fast
 
I loaded the Bergers with H4895 on my single stage press and tricked the powder. But when my 39grn Sierra ammo that I loaded on a Dillon 650 considerably out performed them, it's hard to wasn't to waste the powder again. Maybe I will try a completely different powder next time with the Bergers.
 
I bought a ruger 77 varmint target gray brand new when it came out. Also had a 527 and an encore barrel. Ran all 3 for a long time. I never found anything that shot consistently better than the 39gr BK but, all 3 shot everything pretty well. I played w all the powders and bullets and tested on crows and chucks for many years. Pretty surprising how well 32gr vmax always shot. The 45gr hornady sp was the best 20cal coyote bullet we ever had imo. I guess all the cartridges in the 222/223 family just work well no matter what. All great fun. I have since switched to 20-222 and probably not looking back!

Hornady is definitely hot, a close contender is the Federal premium Nosler ballistic tip,40 grain, ballistically almost identical.
 
It’s 24” and think I tested charges up to what you have around 28.3. I got a good group but I didn’t need to push it that hard. As someone said a p dog won’t know difference between 3800 and 3900fps.
Here is what I had for 28.1

It would be helpful if you would list whether you are shooting a bolt action (Safer/stronger than an AR15 build) or an AR15, which would normally have a lower max powder charge.
