I'm new to the 6.5 and am just beginning to work up some loads. My setup is as follows:
20" saturn barrel;
mega billet upper with side pull
Paladin on/off gas block
First 3 shot grouping was with Hornady factory 123amax ammo.
vel. 2493 with sd= 8. best group about .5"
first handloads were 123 scenar with 2520 in AA brass with CCI400 primer
30.3gr
vel= 2515 with cci400
vel= 2536 with cci450 sd=15
30.6gr
vel=2493 / sd=20 and vel=2578 / sd=19 with cci 400
vel=2556 / sd=11 with cci450
best grouping about .7"
The weather changed from 80's and overcast to 90's and sunny as the velocity increased. Is 2520 that temperature sensitive, or was the difference likely chrony error?
Next up was BLC-2 with the scenar;
31.5gr
vel=2458 / sd=19 and group size of .41
Final loading was 95 vmax with H4198
25.5gr
vel=2717 / sd=0 group .7"
25.8gr
vel did not record, but group of .4 for 4 shots with #5 opened to .7
Overall, no pressure indications. I like the BLC-2 groupings, but would like more velocity. I plan to try some LVR when I get a chance to load some more. Data on another thread here looks promising. I spoke with Dave @ Hodgdon today and inquired as to any data with LVR. He said they had tested it in the grendel but it did not perform well enough. I suspect his statement may have been CYA.
Does anyone have any suggestions for changes to make with any of the previous loads?
Thanks!
Mark
