I blooded the 260Imp a couple of days ago. The 143gr ELD-X sure are the bizzo, rapid expansion at 179m. Quarter on shot on a spiker took out 2 ribs on way in, a vertebrae and finished up with the...

Yeah I saw your 3 shot ES on the other post. It takes me another 0.5gr to equal what I used to achieve since I lengthened the throat. I could have probably gone another 0.5gr on the SF powder but it...

I tried the Superformance stuff everyone raves about. Cranked my 260 Imp up with 48gr as a max load and I got 2906 fps average. With RL17 45gr gives me 2941 fps average. Accuracy was not quite as...

Stay in touch with GWH and he can fill you in with his findings when trying some different powders. N560 is a popular swede fuel....

Nice selection. I went for a bit of barrel length to help me out as well, 24.5" is good without being to much over all rifle length. Im happy with the safe 2940 im getting from the eldx. Confess to...

Depends how you look at it. I started with the idea of using a genuine medium length action for the project when I bought my reamer, then bought a Tikka as the donor. I wanted an improved so I could...

Yep, some sort of step I believe. Would like to see a diagram so I understand it more. Yeah I had a laugh at the Terminator tag :D

Interesting article I read a while ago about the newish RL26 & 260 Imp.
260 Terminator: Initial Review – Panhandle Precision
I see there was a spin off of this same one in the NZ Hunter mag.

Done a bit more shooting over the weekend after getting the throat of the 260Imp lengthened by about 4.5mm to make use of the Tikka long action etc.
Found that I needed another 0.5gr RL17 to reach...

Yeah, I've heard that could be a good one to try. Some are having good results with N560 too. Be nice to be able to buy "sample powder quantities" aye!

Good point, but when I got the reamer cut I owned a Sako M591 medium action and was going to be limited on OAL with that gun. However it went down the road and I ended up with a Tikka for the...

Yeah but we know speed is not always the answer. I'm hoping for a bit of your accuracy in exchange for some speed. Nice work with yours, good that the short throat reamer has worked well for OAL.

Uplandstalker any progress with your loads?

Well a few months have passed and I've fire formed all my cases and got around to loading up some sample full power rounds with 3 different projectiles. I do like the 129gr LRAB's so I poked a few of...

Yeah side by side they look even, though I must run the vernier over them to see exactly. One interesting note is that this design of improved actually slightly increases the neck length when formed...

R93 no I never did on my 257AI either, only had 60 cases with that and they lasted 20 years of normal hunting. Lost a few with split necks but that was me being lazy and not annealing.

Don't quote me but H2O capacity of a standard 260 Lapua case I think is 53.8gr vs 55.9gr for that same case FF in Ackley 40 degree, so I should be somewhere in the middle.
There are a few other good...

Well after reading all the 260AI stuff of late, I decided to crank my project into G
I've gone down a different path to all you 40 degree Ackley disciples and made up a 260WI (Whitley 30 Degree...
