Loaded up a few 147's today behind my load for 140 AMAX using IMR 4451
140 AMAX
Mv avg =2868
ES= 14
SD= 5.8
0.020 off lands
147 ELD-M
mv avg = 2848
ES = 9
SD= 4.7
0.040 off lands
I literally used same charge weight from 140 AMAX load and did not touch seating die. The ogive difference between 140 and 147 is what accounts for 140 being 0.020 off lands and 147 0.040
I'll take these results!!
1:8 twist 26 inch barrel
Took this 147 ELD load out yesterday and it performed amazing!
Keep in mind I have not done full work up yet and it has more potential as these are seated about 0.040 vs my 140 AMAX at 0.020
Here's the run down of some dope
----------------------140 AMAX ------------- 147 ELD
----------------------2868fps------------------2858fps----
590 yards ------3.3------------------------------3.5
1000---------------7.8------------------------------8.0
1600--------no attempt-----------------------19.0
I had been shooting my 140 load most of the day (it HAMMERS) and then switched over to 147 load.
Went to straight to 1000 and gathered dope on full size torso steel on 147.
Weather conditions got perfect so I immediately went from 1000 to 1600. First shot was a miss, second round HIT and third round HIT at 1600
All of this was shot out of my form 1 suppressor as well
Temp = 84F
DA = around 2300
Also, had a buddy shooting his GEN 1 RPR in 6.5CM using factory 147 ELD-M ammo and it was an absolute laser.
One of the most enjoyable parts of the day was us having a shoot off with clay pigeons on a short wood stakes at 1000 yards. I was using my 140 AMAX IMR 4451 load. Results were stellar to say the least.
