6 creedmoor 115 JLK, 115 DTAC, 109 LRHT, 115 VLD

[whatwind?]

here what i have so far with the "new" 115 JLK bullets from JLK with Ed Faber and older 115 DTAC (bare, closed node, rbt) and 109 gr Berger LRHT

6 creedmoor, .183 FB,
30" Krieger, 1:7 rot, 1.25 straight, 4 groove, 237 bore

i had Lapua and RWS 308 win brass made in 6 creed a couple months before lapua announced 6 creed brass offering in 2016?? and just now getting around to this "build"....my first 6mm f open set up and it is such a pleasure to shoot compared to 7 wsm...capt obvious...fired cases weight very similar around 167 gr for both brands, with lapua being more consistent

i am at sea level and this test was done with temps around 55 and actual DA started -60 and moved to +300....these results are with rounds 160-210 down the barrel and are best accuracy so far, just thought i would share, as i dont see a lot out there for new JLK....which ed says has .528 bearing surface

i have not had a chance to stretch it legs yet beyond 100 yards

115 JLK, H4831sc, jam +.010

Lapua SRP, 51.15 gr H20 w/ fired case, CCI 450 primer

I have been looking for information on the JLK 115. I have shot both Berger 115s and newer DTAC. I really like the Berger’s but like the idea of purchasing in bulk with a better availability. Please post accuracy results.

I shot 1000 yd f class Saturday and tried RL 26 and H4831sc and 4831sc was better, less vertical, went with 44gr at +.010 jam
I am pointing this Bullet also, but did not sort OAL or anything else

this is first time past 100 yds with this rifle

 

[Joe Furrer]

This target was JLK?

 

[whatwind?]

Yes sir I only have 115 JLK

 

[Joe Furrer]

Thank you.

1000yd tuning and pointed vs not
+.010 43.70 gr h4831 sc = 3011 FPS avg, SRP

Turned the tuner in about 3 marks to get here

tried LRP with same powder charge and didn’t work, 60 faster, will back down and try it next

 

[whatwind?]

Have been getting the LRP brass dialed in with SW4350 (slowest of all 4350 powders) not H4350 replacement

41.9 gr SW 4350, cci 200, 115 JLK 10 ITL = 3002 fps

tested remington, f210m, BR2 and cci200....rem was shit....

with 115 berger VLD +3 ITL 42.14 gr = 3030 fps, LRP brass best accuracy


my SRP load is still doing very well and got my best 1000 yd result one month ago...all same speeds +/- 3000 fps

 

[whatwind?]

Primer test

41.8 gr on top and 41.9 gr on bottom

the rem primers have a sweet 41 es…cci 200 was under 10

 

[logandiana]

H4831 sc

42.8 gr = 2989

This is my exact powder and load for my 109 bergers. My 6mm CM is a 30 inch bartlein 1:8

 

[whatwind?]

new 6 cm 35 degree shoulder reamer, .162 fb

RL 23 ladder..... alpha LRP, 1x f, br2, 115 DTAC, 5 ITL, 30" 1:7.4 Bartlein

starting at 150 shots down the tube and -300 da yesterday, 60F, 30.29 BP....

40​	2855​
40.3​	2867​
40.6​	2882​
40.9​	2915​
41.2​	2941​
41.5​	2933​
41.8​	2974​
42​	2978​
42.26​	no chrono
42.52​	3009​
42.78​	3052​
43​	3047​
43.2​	3061​

Here is the target to go with this ladder, I got a target camera now to better see the correct impacts per powder charge, easy to see red and blue -and yellow sometimes, green is not

 

[whatwind?]

SRP ladder and LRP group, the DTAC hasn’t been as easy as the JLK for me, the alpha SRP pockets are tight

looking above, really shows the LRP-SRP spread…it even sounds different

A score of 194 first time out at 1000 is nothing to sneeze at. Good shooting....!
