"built as a better than a dasher in the wind at 600"
but my 600 yd range lost its road and no idea when i may shoot 600 again,
maybe at 1000 some where

My Dasher beats your GT in drop and drift at every point out to 1K.......

Are we pretending this hasn’t been done by other 6.5s, even the one everyone loves to hate?

my first 6.5 since 6.5x55swede.
bigger than a dasher smaller than a 6.5x47.
just to be different
the only competitive 6.5 i have seen in BENCHREST is the 6.5x47

Nice group! The real trick is to do that every time! I have problems doing that.

 

[lb-ft]

I think it’s cool to try new ideas. I especially like the long barrel you’re running; I expect you’re extracting the full energy available from nearly every grain of powder.

Bigger than a Dasher but smaller than a 6,5x47; sounds like a 6.5 Arisaka. WH

I love the 6.5 jap case . I’ve built a few great shooters .

I toyed with the idea of building a Jap for use as a silhouette rifle. It should be perfect. I use a Creedmoor but I think it's actually a bigger case than necessary. WH

yeah....me too..

 

[762plinker]

no , i want SMALLER

 

[762plinker]

well so far no luck at getting smaller.
may change powder
started a fire storm when i asked a simple question about neck tension for jamming.
just bought 3 new bushings
more work to do

 

[762plinker]

so today, in an effort to find smaller with the same powder i went to JAM vs jump.
4 three shot groups at 0, plus .005,.010 and .015. the only change was to use a 1 thou smaller
neck bushing. no other changes
2 of the 4 groups went 2 and 1 with the 1 wrecking the group.
not in order but .276,.297,.304 and .405
the bolt cycled harder, but the velocities remained the same
not impressed going to try a different powder.
( 276 is nearly .04 better than the .315,BUT my first 1k rifle shot .315 at 200...so i got goals)

 

[762plinker]

so moving on, RELOADER 17. i was not impressed with this powder in a 300 wsm. quickload shows potential in this bullet/powder volume mix
today was a simple ladder( education time, this was 10 single shots, not 10 3 shot GROUPS)
38.1 2865
38.4 2893
38.7 2901
39.0 2923
39.3 2971
39.6 2987
39.9 3021
40.2 3040 100% CASE FILL normal bolt feeling
40.6 3074 101% case fill firm bolt
41.0 3118 102% case fill very firm bolt
pretty sure i will skip the last 2, but if the next top 3 show any potential in group, i will have an advantage on a dasher.
i will plot vel/powder and see if it show any nodes

yes but...i aint done
look at today's data
dasher 105 at 3025 600 3.5 drift/10.6 drop 1k 6.7 drift 25.2 drop
6.5 gt 130 at 3040 600 3 drift/10.1 drop, 1k 5.7 drift, 23.4 drop

just saying there is a possibility

maybe you can share the make and data, vs opinion
i knew when i posted that you would come back with a "better" answer

It's not a better answer nor opinion, just fact......

Berger 105 Hunting VLD's pointed give about a half percent better BC over stock.

28" Krieger fueled by Varget started by Federal 205 M's shot over an Oehler 33.
