260 Rem, AI & Imp

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

Drop data puts them at 3020fps, Magnetospeed puts them at 2980fps, ES of 7fps over 5 rounds.


I wouldn't say there is bugger all accuracy difference going to palma brass - not any more than you would gain with neck turning anyway. 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.

You have a standard .260 rem doing nearly 3000fps with 130 gr bullets?

Yes, 26" barrel, minimum SAMMI specification 260 Remington chamber except for the neck which was slightly tighter.

See I never bothered to measure mine. The projectiles were always loaded to suit the magazine length - once I determined that seated to that depth they didn't contact the lands. I expect they had quite a jump towards the end of the barrel life.

Blowing a gale here this morning, no load testing today :(

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.

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

Yeah have shot a few - deer , goats, rabbits, magpies, hares, etc. It has been relegated to a middle distance field target rifle now though - it shoots awesome but is a bit on the heavy side for hunting. I have a Sako 85 hunter in .243 that is first pick when I am hunting now.

Magpies and rabbits must be impressive

Not too much really, in my experience the 130gr bergers need a bit of body depth to really open up and perform i.e. I think they do a couple of inch's of penetration before they come to pieces. Freaking impressive performance on fallow and red deer, and on half grown to full grown goats - small goats and small game though they tend to pencil through a bit and then open up. 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.
130 sirroco - being closer to lands increased the pressure much more quickly?

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.
