Thread: Super Pig calibre Question...

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.

Barrel is 18" it's shooting 168 classics hunters. I'll have to check the load data it was load developed by NZ Hunter not me. I'll come back to ya.

Keen to hear about the ballistics in comparison to the 260 / 6.5x55.

Yeah, I know it will be loud as F**K and burn more powder for little gain over a 260 etc... maybe

But sometimes you just want to find out for yourself

Keen to hear from those that have experience.

Thanks Team.

8x57 or 44mag are the first two that come to mind, this year i plan to build a 400 H&H Magnum

Handloads or factory?

Fast burning powder?

May I ask which powder?

Not after your load data.

Yea, RL15, can't get it at the moment
Vht n550 gets close

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..

That will be my next build after the Sako 270w barrels burnt out will rebarrel to a 16" .284w and should be good for 750m, after using a 12" barrelled 300 Blackout, I got the bug for short barrelled rifles.
