Berger 144 @ 6.5x47

[Sandstorm]

Went out this AM and tested the new Berger 144 LR Hyb
in my 6.5x47 Lapua...
Came away with .020 jump using 37.7gr Varget. If I didnt have the flyer
it would have been a solid one hole group. Interesting to see the difference from
.005 in the lands to .010 out and .020 .030 .040 .050 jump.
.015 to .020 seems to be the ticket same as the 140gr Hybrid im shooting with the same powder load. Im thinkin they will work well, just wish all the Competitions wern't canceled........
I got a bad feeling its gonna be a long time too.
Stay safe my friends..and be well.

Did you record the velocity?

I am looking to start load development with 144's in a 6.5x47 with H4350 when i get my shot marker and the lgc opens back up.

Interested...

I have a new 6.5x47 bbl on my f-class BAT rifle - and been testing the 147 ELDMs.

Getting good speed - but only fair groups at 300 yards.

Thinking I may abandon the ELDM and try the 144 Bergers...

Velocity was 2779 and SD 6.2 ES 16....Not too shabby....I think I can further tweak the seating a bit.

what is your freebore

.167 cut for VLD's ..It works well for long projectiles..Not so much for the SMK's
But they still shoot ok at 500 and 600.

Looking for an update...144's are here needing to be load tested.....

My 6.5x47 Fclass gun at 300 yards - with the 147 ELDM.

Best group so far, with RL-17, N550 and H414 all tested on paper.

Velocity here was just a hair over 2700 from a 28" Kreiger.

Ready to try the 144 Bergers.

I think COAL is not correct could it be 3.112?

That is the case base to Ogive dimension using the Hornady 264 dia gauge attachment.
