Gave better velocity and case life of all the traditional and recommended powders I have tried in my rifle.

When I was building my 260 Imp, I researched a lot about suitable powders and picked W760 as being favourable, so I bought a tub of it. Then some bugger mentioned RL17 and yes it gives great velocity but I've shagged some cases proving it. Guess I should dust that 760 off and try it aye

To be fair there is still bugger all info on the improved version. Barrels aside there are a lot of extreme/bullshit claims in the velocity department imho.

I searched heaps as well when I first got it and tried everything (OCD).
Yup. Best velocities came from 17 but you just couldn't get it when needed.

2209/4350 were reliable and accurate but pretty pedestrian in my barrel.

I can't remember who, but someone on here suggested to try W760 and I did. Havent looked back.

I still use 2209 for 140 class and up but rarely shoot them now apart from a bit of steel.

Cheap and dirty old Hornady 129 interlock is as accurate and deadly in close and far out as I need it to be. Barrel has had a few rounds down it now and going well.

Looking to get a 7mm barrel of some description done for steel and so I can take my own rifle on a moose hunt overseas. Unless KJ lends me his 7mag barrel

Have you tried superformance powder with the 140s Mate? With Lapua brass it really gets things chugging.

Yup. Didn't get much more velocity than 2209 in my barrel which is 24" Accurate tho.

Funny that you found W760 different to 2209, according to ADI they have the same burn rate.

How much of a difference did you find in speed?

It may have the same burn rate on the books but it certainly does not perform the same in my rifle for the same weight charge.
I get 2980fps with 760 and the 129 interlock with half a grain less than the 2940ish I got with the same projectile and 2209
Case life is also already better.

Haven't changed primer or seating depth so it must be a how. Not a how fast it burns thing.
The 123 Amax has an even bigger speed gain using 760 over 2209.

Accuracy with both powders is roughly the same.
