What exact ammo were you using ?
who are you asking?
As for me, I hand load everything I shoot. I have been hand loading for over 40 years. I shoot mostly 308 but have replicated the loading process for the 6.5 Creedmoor as well. In simple terms I am using (.308) Hornady 168gr match, with 42.5gr of BLC-2. But the magic is in the prep. Cases are sorted by manufacture and the number of times fired, full length sized, trimmed to the same length, seated with a die that does only that (adjusted for to the brass being loaded), and crimped using a factory crimp die. Every round is a close to mirror copy as I can make it them. These are not hot load and clock in at 2450fps (out of a 22" barrel).
The 6.5 is like wise loaded using 130gr match and 32gr BLC-2.
* I use specialized seating and crimping dies for consistency
* I use BLC-2 because it meters really evenly. I know... this powder has been around for decades. But I have yet to find anything that meters as evenly as this powder.
* I trim my cases to the same length every time to ensure case volumes are consistent.
* I sort my brass because each manufacture and firing changes the wall thickness... which affects seating depth, crimp tension, and case volumes.
* I use one brand of primer for consistency.
* Cases loaded and fired three times and then tossed.
This formula works for me and I can get sub MOA groups. Why mess with pefection?
just my 2c. Please note: I am not endorsing these loading for anyone. Every load needs careful testing and evaluation to find a combination that work for you. These are target loads and not a hunting load, and I worked the process and 308 loads up over the couse of many shooting sessions years ago. The 6.5 loads are new for me and I may tweak them some in the future. I am still in the evaluation phase for these... but the lading process is the same as experience and knowledge indicated that it is a good working process. So I aint messing with it.
