Anyone used this yet in a 6.5 CM?
I just ordered 200 of them.
I was wondering if they were more like a 140 ELD or 147 ELD?
I am using RL16 and Hornady brass for both ELD's and have good results at 2830 fps and 2750 fps to start from.
I will post my results in a couple weeks but wonder if any of you have already begun load development???
~43gr RL16 @16 off gave 2820 FPS out of a 30" tube.
Very good accuracy. ~.75" group at 300 yards.
Was that with Alpha or Lapua brass?
I just tried loading it in unfired Lapua brass and willhave to wait until they are fire formed.
Anyone else tried this bullet yet?
Here is some very preliminary results with the 144 grain Berger with both Lapua and Hornady brass.
Looks like I started too high with the Hornady brass. 42.7 RL16 was accurate w the 147 ELD at 2750 fps. Will back off 100 fps next time.
I knew the Lapua had less case capacity but was still surprised I could not get a 147 grain up to even match factory ammo velocity in new unfired cases. Looks like I will use the 140 Nosler RDF to fire form Lapua brass as it was very accurate even in a composite group. then work up a load for the 144 in once fired Lapua cases.
144 GRAIN BERGER.

Minus 20 fps from new brass. 2 shots touching at 200 yards.
140 NOSLER RDF

42.0 2788 fps
42.2 2787 fps
42.4 2831 fps
Entire string very accurate at 200 yards. (Node at 42.1) Use this to fire form Lapua brass.
147 HORNADY ELD.
Lapua brass (new)/RL-16/CCI 450/2.899-2.921 OCL/Not sized
41.0 2612 fps (fouling shot after American Gunner ammo)
41.2 2610 fps

41.6 2649 fps
(41.2 grains max without using a drop tube).
147 Hornady ELD.
Hornady brass (3-fired)/42.7 grains RL-16/210M/.290 bushing/shoulder set back 0.005 by mistake.
2807 Average. (About 50 fps faster than normal).
Les accurate than normal (2 x 1 ¼ inch ES @ 200 yards).
What kind of groups were you getting with the 144?

I have had great results with the 140 & 147 ELD's, but they seem to fall off around 1400 yards with the H4350.
I'm getting greedy and want to reach out a bit farther, here at sea level.
Try some RL26, people are getting crazy velocities with it and heavy 6.5 bullets.
I got to the range w new Lapua brass yesterday, the 144 Berger, CCI450, and two 5 shot groups of RL16.
42.0 and 42.1 grains. Velocity a cool 45 degrees average 2753 and 2756 fps.
1 1/8 x 1/2 and 1 1/2 x 5/8 inch group w 6- 24 X Luepold and Tikka in a KRG Bravo stock. 200 yards.
I used Area 419 drop tube and funnel and was able to easily seat bullets.
This is not an improvement in accuracy over the ELD's in Hornady brass. But I have not spent much time with the Berger's either.
The 140 and 147 ELD's are still the easiest to get groups out of in my Tikka. Right now Id say the 144 Berger is easier to tune than a 140 RDF but "a drunk monkey" can load the ELD's.
I shot about 40 140 RDF's in new Lapua on steel targets out to 1,100 yards and was hammering left edge of 9 inch plate at 600 w just 3.3 mil elevation. 2790 fps, a fairly mild load but accurate. They are flat shooting but like a lot of jump.
I did finally get around to trying several combinations of new Lapua brass, once fired and Hornady. Preliminary results below.
I hope this might save someone a few trips back and forth to the range. Tikka CTR action and barrel in KRG Bravo stock.
