Nice hair do!:thumbsup:

I will he interested to see your chrony results with an 18" tube

I reckon N550 would be worth a try with the short barrel.

My chrony turned up so headed to the range.
140 Amax Lapua brass CCI primer 45.9gn 2209= 2600fps on the button
140 corelokt Remington brass CCI primer 45gn 2209 = 2450fps


@Beavis

I forgot to add, the amax's were doing 2720 before the chop.

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.

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.
