Sweet think I'll take mine to 18. 2600 is plenty.
Sweet.
@gimp, I ended up getting 3050 with the 100's with no pressure signs 51 grns of 2209 group was 2/3'rds of an inch :D
I'm trying some 120 pro hunters as I can't get hot cors for love or money.
Much better than 2200fps.......!
Although the Amax might not work well at 3000+.... might be better off with the slower 140gr at 2600-2700. In terms of how it expands.
My thoughts too. I used to run 140's amax and corelokts for that reason but I've decided to run just one bullet now for everything hence the 120 sp prohunters. Idea is 1000ftlb at 400m and I will be happy.
I've been thinking about chopping a spare 6.5x55 barrel to 16" on my R93. Was going to do a 308 bushpig but I already have dies, projectiles powder etc. I wonder how a 16" 6.5 would go?
At the range right now doing a ladder test with 120 pro hunters, the things are fucking one holing across a 2gn powder difference!!! Pics to follow
In this group there is 6 shots, the way the FPS read out was two where slow (low 2500's - lower left) with 44gns of 2209 then there 4 "faster" ones from 2570 - 2650 (where I wanted to be) the main group with 44.5-46.5 gns 2206
at the groups largest, its .52. After shooting 4 of the rounds I had to walk up to make sure I was hitting the target as I couldn't see the bullet holes.

had the range to my self.

Bugger I could have joined you!
You in taupo Maca?
@gimp @Pointer Heres something thats annoying, Went back to the range today, and on 3 different loads I shot 2 bullets in the same hole (like .1" off each other) and then there was a flyer an inch or so off!!
only thing i can think of is the brass might be getting old now, I've had it for 3-4 years and probably shot them all no less than 8 times (Lapua) any other ideas
I let the barrel cool a bit between each shot - in that bottom group the flyer was the first shot of the day.

Clean tube? Don't stress sometimes we all just have shit days shooting paper:)Quote:

Yup. Don't think it is the brass either as the flier in each group would have to have the same issue looking at it.

Old instructor would say that being horizontal flyers trigger pull is to blame
Weigh your projectiles perhaps. Some batches of bullets are terribly inconsistent with weight. Another variable to check.
Thanks boys. Will have another go this weekend
To revisit this, ended up with 120gn pro hunters doing 2600fps groups are an honest .25-.5". I've only shot reds to 70m and fallow at 30m but it drops them like a sack of spuds. Range finder binos on the way so will be able to push the distance later.
Tried any N560 @Timmay ?Quote:

Attachment 66142 was sighting in hence the POI. Two shot groups @ 100m.
Na me neither and I have a factory R8 barrel- longer.
Accuracy is good using 140 amax and 2209. Want to try a different powder soon.
What about that RL19 stuff? that can give better velocity apparently.
Maybe in longer barrel lengths 20"+ I would imagine?Quote:

I also use that in my .243 and it also shows extremely tight 5 shot groups.
-This all stems from somebody's comment that an shot from a nearly full case will give a more repeatable Shockwave to the back of the projectile..... Seems to be on par so far. Could be bollocks tho
IMR 7828, and or RL22 - the 140 VLD has a shorter bearing surface and that helps veocity gain. (the 120 TTSX gets 2209)Quote:
