After a range trip this morning, I discovered my 308 dope is superior to my 6.5 creedmoor. And I don’t know what is going on. To gather the dope below I used weaponized math due to not having a chronograph.
Specs:
AI AX
Factory 24 in, 308, 1/10
Win tactical 26 in, 6.5 creedmoor, 1/8
Factory Ammo:
6.5 Creedmoor Hornady 140 ELD Match
308 Hornady 178 ELD-X Precision Hunter
308 (Mils) Dope:
100 - Zero
200 - .5
300 - 1
400 - 2
500 - 2.9
600 - 4
700 - 5.9
6.5 Creedmoor (Mils) Dope:
100 - Zero
200 - .5
300 - 1
400 - 2
500 - 3.3
600 - 5.2
700 - 6.9
800 - 8.1 ( Range finder died and I did not mark my targets when I set them but I was pretty this was 800)
These loads were shot on two different occasions and ranges. I recently built a new range and the 6.5 Creedmoor was the flavor today. However they are both flat. And about a month apart in when the dope was gathered.
The weather was pretty similar, around 30 degrees. But today with the 6.5 I was battling the wind pretty bad. 20 mph with gusts up to 30mph. For the 6.5, targets 100 - 500 had the wind at 9:00, while 600 - 800 had winds at 10:30 -11:00.
600 wasn’t too bad but I felt like the wind was really giving me more fits than it should of. Past that I wasn’t consistently splashing on either side of the target. I will attach the 600 target to show how the vertical spread (after the first bottom right impact) was good but horizontal was very erratic. And once I went past 600, it felt like things went to hell in a hand basket.
Other notes. The 6.5 barrel is fairly new, I have about 160 rounds down the barrel. 40 in the first outing and 120 today. The only cleaning on this barrel took place after the 40 rounds with a bore guide, Parker jag and Hoppes 9. Patched until it came out clean. I boresnaked the 308 and that’s it.
I didn’t check my “group size” when I started today. I shot one at 100 and 5 at 200 which resulted in a small gray blob with the white paint being taken off, good enough for me.
I am leaning towards the 6.5 ammo being very slow.. and try some 6.5 precision hunter. But is there anything else I should look at?
Thank you
