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.

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?

he probably does mine are doing 2930 and their not hot

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?

Try win 760 as l had the same problem with 2209 760 was much better.

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?

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