Sincerd,
When I had a brain fart one evening I ordered a RH Savage Tactical {I'm Left Handed} in 6 CM. I also ordered the Lyman PRS book.
Checking what Lyman listed for loads I found I had three powders they listed. Long story short, The RL 15* load with 108 ELD's shoots
< MOA out to 300 yds.
I was headed to the 600 Yd.range today but some county govt. idiots doing a "controlled burn" let the fire get away from them. Several homes were lost, and I've been helping neighbors that were effected. Maybe tomorrow.
Reading here, I read where RL 16 is used with the 105-108's and RL 17 is used with the 110-115.
H 4530 has been ordered
As Rosana Rosana Danna used to say " Ain't it always something"
8208 is my go to powder for my 77 gn. AR loads, besides the 6 CM RL 15 is my back up to N 203B in 308 AR's
* I think they use a little coal dust because patch's look like they were in a coal mine.
