Thanks Dicko for that info, I use 2209 in the 260 with great results and truth be known I should use it in the Swede as well, but at this stage I'll see where the 2213 leads me. Interestingly I have done a load with 129 gr Hornady and 42.5 gr of 2209 and got 2650 fps and good grouping, but I'd be replicating the 260 so I will try something different.Quote:

I would be switching to AR2209 for that barrel length (and drop the charge down to say 42gn and work your way up to a node).
I use 2213sc for my 28" target rifle but i never load more than 45.15gn or its too hard on the brass long term / slight reduction in precision.
I would also say, ditch any 'average' brass (like winchester or federal) you have and make sure you have good quality stuff like Lapua if you are pushing this out to high velocities.
Makes a big difference. I find Norma to be almost on par with Lapua. And regular large rifle primers seem to be better for precision than magnums.
But shoot what you got eh. its only slightly different imo.
I once tipped my rifle upwards and screwed on the suppressor, some chunks of carbon got loose and went back down the barrel... jammed up nicely with my stupidly precise ammo i had made.Quote:

I persevered with the 2213, got just short of 2700fps but the accuracy wasn't there (1.5 Moa), I mucked around with seating depths, neck sizing, but couldn't get it any better. So, changed to 2209, immediate improvement, got 2690 with 44gr pushing the SST140's and tighten the group to 1 MOA. I'm sure I'll be able to get it better, but I'm running out of time and need to go and shoot some animals.
I've been following Magnetite's thread with interest, and one of his last posts regarding the accuracy between 2209 and 2213, so I will need to go back there and see if I can improve. I also need to get the gorse out of my pockets and buy some new brass to use as a bench mark.
Anyway, thanks very much for all your help and advise, it stopped me from guessing. Cheers.
@Lambie Is your rifle suppressed?
Hi Magnetite, No, it's not suppressed
47 grn N560 gets me 2700 in my two Husky 1640's. Thats with Lapua brass and 143 eldx. I did push it higher with up to I think 49 grains but 47 was accurate and will be kinder on barrel and case. How many reloads you guys get from lapua 6.5x55 brass?
Some of my brass has had half a dozen firings, but someone who keeps better records than me would be able to better answer that. Because I'm so tight, I keep reloading until I see pressure signs, and then I biff it, not the best way, but.
my first mrs needed a blardy good neck size (strangulise) :)
@Lambie that could be the difference. If the powder hasn't fully combusted at muzzle exit the gases can upset the bullet. Suppressors can help strip these gases away from the bullet. I've pondered 2208 for lower muzzle pressure, but never tested it.
Magnetite, you could well be right, the rifle hasn't been re-crowned so there could be imperfection there. That might be the next step, I'm not a fan of suppressors, so won't go there. But I did get the gorse out of my pocket and brought some new brass so that will give me my "bench mark", so we'll see were we end up.
