Thread: 260 Rem, AI & Imp

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 hot

I'd make that trade off.

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.

more than 2500 rounds through the original barrel. Accuracy had dropped from the 0.5MOA back to about a MOA with the more and more occasional flier. Yep, a compromise i was happy to make. Given i pretty much only compete in field matches the drop in accuracy was barely noticed.

Think that now the temperature has finally dropped under 30 degrees it's time for a night on the bench, gonna cook up some VLD's for the 260, and need to load up some more LRABs for 270.

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 brass

Yeah I have 'plain' 260 Lapua brass I FF...I feel the dark side pull of neck turning though!

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 ?

shot this on friday when i got me new HD vid cam ... looks better full screen
