@R93 @Beavis
Using factory winchester brass on its 3rd firing Win760 (49.5gr) 140amax fed LR out of a 21" barrel I got 2,863fps as average, fastest shot did go 2,906.
I'm thinking of changing completely now though and going 130swifts and N560 but it's $$$ for a poor bugger. I reckon I would get them going 3000fps.
Roger. I'm working up a 760 load for my standard Swede. Might make 45gr my max since I am inventing the load data.
Yeah bro my tikka 6.5x55 was getting 3050odd on N560 with no pressure......shouldn't of sold that @Andyanimal or his mate robbed me:)Quote:

Was that with 130''s Brads?

R17 also gives it good shot up the arse to, both will eat the throat so don't put bore scope up it once you done 2 250 rounds lol. I'll look at my load data once off grave yard shift. .

Same here, $95 for a pound is crazy when I get a pound of 760 for $68Quote:

(By the way this is tounge in cheek eh guys, please don't try it really i mean it.........)
Nah she'll be right, I'll use a hot glue gun and add a bit of pvc pipe to the neck to hold the extra powder :DQuote:

I would expect you to get 2950ish with sciroccos easy in that chambering.
21" barrel is limiting in most 6.5 chamberings I reckon.
Dunno if I would use 760. RL-17 or superperformance will go well I reckon.
Sidney had a 6.5x55 ai. Try sending him a message for some ideas.
Not knowing a lot about the 6.5 range, but is 6.5-06 the answer? Or, what about a gonzo?
Yeah that'd be awesome thanks! Much appreciated. I actually only thought about using them because you said they are good.
Had a 6.5-06 and loved it.
I am now using the same bullets in a .260 Ackley and getting 80 fps less on aveeage than the '06.
Pretty insignificant out to 750ish really.
@Toby
By all means don't start at these you won't get near them wouldn't think but work up to these.
Built on a Barnard s action with 28 " barrel.
140 amax
Lapua formed brass
215 primer
79.8mm oal
52gr r17 for 3170
Same as above but n560 was 3190
130 vld
Lapua formed brass
215 primer
80.2mm oal
53.5gr r17 for 3280
Don't start near theses tho drop way back to 48 and come up slowly, if your slapping up Ackley cases hard as your other photos she's bloody hot, invest in good set of mitutoyo calipers or outside micrometer and measure case head expansion, if your moving or marking up Lapua brass she's at the high end.
My 3.50 worth

Toby have you tried 2209 yet. It might not be worth going to 560 for you if price or availablity is an issue.
In my old Mauser 6.5x57 AI 51.5 grains of 2209 with a 129 SST gives 3030.
From memory I settled on 50.5gr N560 behind the 140 AMAX @ 3050 out of a 24" barrel. I pushed it as high as 3170, (around 52gr) before getting really obvious pressure, but brought it back for sanity reasons...
Pretty sure that Crazy was running 49gr N560 in a standard 6.5x55 sako for 2900 at one stage... was a pretty stout load for that..
Didn't do much with RL17..
I reckon you will love getting over 3000fps with 130g using a .270 Toby. Now there's a man's calibre . . . . . . lol. 3200fps with sst. Good varmint round but stay away from the deer and pigs . . . . . hahahahahaha
So it was pissing down raining today so we thought it was as good as any other day for a hunt.
Anyway funny thing happened. I got pressure signs on my brass that I shot an even managed one where the primer fell out. Hardcase alright, it was a lot colder then when I tested those loads and had backed off from when it got hot when testing so didnt think they'll do what they did but there you go.
On your lapua brass? What speed etc you end up with and load?

Nah I haven't managed to get out an test those loads I done in the lapua brass. These were just some loads I had left over. Thought I might as well use them while I can. I have a feeling the one where the primer fell out was one of the old brass with loose pockets and it slipped into my good brass pile
Out of the few I fired these ones where the ones that showed signs, the others were fine.

Of the bottom picture, the two cases on the left side look like they've has a thrashing in the past going by the imprinted bolt face marks on them.
The current load looks mild as the primers aren't even beginning to square off on the edges of the pockets
That should have been their 4-5th firing now but I think some of my rooted cases from when I went too high in the testing got mixed into my good pile
Compressed load? :pacman:Quote:

Nope. How do I go about doing that?
Anyone know why the loads were shooting hotter then they should have been going off the day they were tested? I thought it was a hot day that made them go hotter not a cold day
Heavy fouled barrel?
Hot barrel and a chamber, round sitting in hot chamber to long before shot.
Tho you said you had got them mixed up could be they where rooted anyway from previous loads. Bin then all start on your new lapua brass and mark the head when fired each time on resize with small file. Then you know how many times they been around.http://img.tapatalk.com/d/14/08/24/u2y3ubub.jpg

Yeah. Thats my plan now. I already have the test loads in the lapua brass sorted just need to test them now.
That shells been around a bit hasnt it, how much more do you think it'll take?
If/when you get stamps go back good 1.5grnQuote:
