No rivalry mate, just inspiring us to get out and shoot! More of a personal challenge to knock off the 1000 yard target.
Shot back in January this year. That is a 10" target and was planed about 980m if my memory serves. I shot this group as a test for the load development on the brand new barrel (hadn't even been blued as you can see in the photo.
Rifle is my .260Rem Sako 85 varmint. Group was shot with 130gr berger VLD-H, lapua palma cases, AR2209 powder, and federal small rifle match primers.

Large rifle primers?
Palma brass uses small rifleQuote:

Nice shooting Gillie. Did you settle on the 130gn VLDs, what did they chrony at?
Thanks Ryan....haven't heard of that for 260....much difference accuracy wise?
Im not sure, I have some Palma 308 brass I bought and was gonna size to use in my 260 but havnt got round to it yet
I have read small primer is meant to have an advantage, but not sure why or if even how much.
mainly so you can run higher pressures as there is more brass in the head but not good for the throat if you you run hotQuote:

Yep still using them. I think they are a pretty efficient projectile for the 260Rem if you are feeding from a standard small action magazine. I would prefer the 140gr hybrids for their BC but they simply take up too much magazine and case capacity. Drop data puts them at 3020fps, Magnetospeed puts them at 2980fps, ES of 7fps over 5 rounds.Quote:

What you gain with palma brass is a stronger case design that you can push to slightly higher pressures than standard 260 cases. For me that doesn't amount to much as my load i about a grain under where i started to notice the increased recoil and thought i had better stop increasing the powder load - didn't actually see pressure signs on the cases. But i have about 300 palma cases in total for this 260 and have put about 3500 rounds through them (over two barrels) and have thrown out less than 5 for either split necks or loose primer pockets. Some of the original 100 lot of cases i got have done easily more than 15 reloads now.Quote:

I need a bigger bench!

I would be keen to try some Palma cases in 260AI.
I can probably give you some of the 308 ones I have, Im not too sure on the ins and outs of sizing, then fireforming, plus possibly neckturning, maybe easier with straight 260 brassQuote:

You will get more velocity from standard brass over Palmer brass both loads being equal.
i have only put 8oo through mine and have lost 0.047" of the lands so not real impressed with MADDCO barrels ATM but it is accurate but for how much longer ?Quote:

Got my first load of 140 VLDs ready to go, will test them tommorow and hopefully post a video with results. Have decided to use Vit N560 powder, starting at 44grs

he probably does mine are doing 2930 and their not hotQuote:

Shoot any animals with that thing @Gillie or just steel?Quote:

Magpies and rabbits must be impressiveQuote:

The 130gr bergers are not a varmint bullet in my opinion.
40gr V-Maxs at 3200fps out of my 22K-hornet are much more impressive on small game.
Got out this morning and had a crack at the 1000 yard shooting. Conditions were good with very little wind and about 20'c warm and sunny. First shots were high with 1 from 3 hitting the top of the target (20 x 20 inch steel plate) I dialled down 1/2 MoA on the second attempt with 3 solid hits. Took a total of 32 MoA at 995m or 1088 yards to impact target. Had about a 6 inch spread of shoots in the 3 round group.

What powder? To kick an old thread back in the guts. Obviously a 26" vs my 20 but hit pressure early using 2209. Yet to chrono.Quote:

I know others have tried different powders. I started with 2209 like you had pressure signs also, the tried Superformance powder which is a slower blend of powder I used in my 300wsm which gave good results. Worth a try?
2209 and no because i do all my load development starting in to the lands
as if it don't work out there is only one way go and thats back off , so far
my 223 is the only rifle that don't like it touching . ;)
Try win 760 as l had the same problem with 2209 760 was much better.Quote:

I found the opposite, I was developing a load for the 139 Scenar and got pressure real early using w760, could only get them going about 2670 before getting sticky bolt and ejector marks. How do you find the temp stability of 760? Have read it can be quite variable between extremes of temp?Quote:

Still early days but got higher speed than 2209 before pressure
Have just got some super primacy to try.

Can you tell me what load you are using of super proformance as I have some to try in my 260AI with 130 SwiftsQuote:

Start around 45grns and you will be close with superperformance I reckon.
