Thread: 260 Improved

I wanted to build something on the 308 case so decided on the 260 improved.
This one is built on a brand new T3 Tikka with a Limbsaver & 23" Vulcan barrel.
It has a fluted bolt & barrel.



It performs pretty well with the 140 amax, the only projectile I have tried.



Thats a pretty nice speed, it will go faster but it a bit harder on the brass.



Quite a neat useful little longish range round with the 140s

I might have a play with the 120 GMX or 130 Sirocco.

Good speed there for a 260, touch under 3 nice

Not as fast or as accurate as my 26" standard 260, but it is shorter & much lighter......

Well it wont be at its best till the 3rd or 4th use of the case if using Lapua or similar quality brass. Its amazing 3" in a 6.5 can gain so much speed from less capacity.
I would love too know the load but like thats gunna happen

He was talking about range I think. Insinuating it is in fact a useful LR round. It has won a few accolades in LR circles.

You assume a lot Dave, it is Lapua brass & it has been fired 5-7 times so far, as previously posted it was with Reloder 17

My 260 has a shorter throat than the 260 improved.

The standard load I was talking about, you never gave data for that iirc? Shorter throat gains you what Greg? 120fps with 5% less capacity than the improved. It certainly isnt Barrel length as that is a trade off in pressure.

I have lost count how many times I have said it on the Forums, ADI max load of 2217 50.5 grains, super compressed

why is that?

It takes a few firings for the brass to "settle down" & conform properly to the chamber, especially with wildcat fireformed cases.

The 1st firing on any new brass is never the best, the 2nd will be better

I built another 260 improved, on a Model 7 this time.

I put a VX1, off another Model 7 I got, on it, it has the usual light weight components.

I weighs 6.4 lbs as it is with the heavy factory plastic fantastic stock.

It will be 5.5 lbs when its nice new Carbon Fibre one shows up

It pushes the 120 GMX at 3075-3100fps so quite useable.

Hey greg how does the 120gmx go agaisnt the 140gr Amax at both killing and long range?
