I was considering building it on a Sako 85 but there is no lefty in stainless. Once you get rid of all the shit tikka bits they are actually a reasonable action.

Fast burning powder?
May I ask which powder?
Not after your load data.
Dont waste your time chasing every last fps, it doesnt matter in the real world, it wont make a difference, all it will do is cause head aches and frustrations. And dont listen to silly old cunts
I have a 'bush pig' 6.5x284 - started out as a factory Tikka stainless 6.5x55.
Has been, rechambered, shortened to 17.5" and a durillium suppressor fitted (along with fluting, half bolt etc etc).
Rifle has been a bit of an experiment (bought the rifle when I exchanged my credit card points for H&F vouchers - it was either the rifle or home appliances etc for my wife!)...
Only in the initial load development phase. I have started with Norma 130grain Diamond Lines (which I have several hundred of - but to be fair are probably not the best for pushing to max velocity given a long bearing surface etc). I am using Reloader 17 (which has given the best velocities so far - over AR2209 and AR2213SC, which I have also tried).
To be honest, it has been a bit disappointing.
I don't have direct experience with 6.5x284 in longer barrels (although do also own a 6.5x300WSM and a 6.5 Rem Mag - the latter has only has about 1 gr greater case capacity over a 6.5x284). Looking online with long barrelled rifles it appears that some people are getting close to or over 3000 fps in 6.5x284 with 140 grain match projectiles - with up to - or in some cases over - 50 grains of RL 17.
Using the 130 gr Diamond Lines (i.e. 10 grains lighter than the above) seated well out (but not into the rifling) I have maxed out at around 47 grains of RL17 in Lapua brass. After that I was getting ejector marks etc. Shoots very well but I am only getting an average of 2711 fps. If the barrel were 16" like a true bush pig (if there is such a thing!) I expect it would be under 2650 fps.
Although the Diamond Lines have a great BC (.548), the reality is that a straight 284 Bush Pig (i.e. 7mm) kicks its arse 'grain for grain' when loaded with a 162 gr Hornady Amax etc. I expect even a 7mm08 will do better than 2700 fps with a 130 grainer (albeit with a lower BC)...
By further comparison in my 6.5 Rem Mag (again, effectively the same case) I am getting 3213 fps average with a 129gr Hornady on top of 54gr of RL 17 in a 24" barrel.
I am going to try some different projectiles (probably 120gr ballistic tips) but have put load development on hold as I don't want to burn up any more of my remaining RL 17.
Hope that helps...
I found the same results as Huntsika I used 2217 and was getting 2800fps with the 130 Nosler AB and that had a 20" barrel.
I tried RL17 but it was no better so I sold the bits and went down the .260AI 10 grains less powder same speed..
