So yeah, the 6.5/.284 is getting 300 extra fps but at considerably higher pressure.
I was comparing 260/130 data to 6.5/130 data.
Even so, I'll take the performance and eat the pressure. After all, it's a hunting round I'm looking for not a target round.
My experience is that barrel length makes a difference of 25-30 fps per inch on average, not 20 fps
Ok 5 fps dif. I did say 50 fps less to take variations into account.
This is really splitting hairs!
