Get a single stage FIRST ! Then buy the progressive press ,second.
77gr 223/556 projo's are kind of long, you might want to start out loading 55gr,62gr and 68/69gr projo's.
Can't comment on CFE223 in 308's but in the 223/556 case my loads are near the top of the load range and I didn't see any pressure signs.
With the 800X in the 10mm the overly hot load would not chamber the next round. I think it was.3 to .4gr less powder from winter load to summer load. Temp range (50° to 60°) in the winter to (105° to 115°) in the summer. The other big difference is the primer selection. An example was going from a CCI350 to the CCI300 for summer loads.
Read a thread I did on primers, very informative. Look at some of the charts and choose a less powerful primer.
Ron invite me and I'll pelt his ass into submission if he stands to the right of me. Does not matter the distance,zero to 30 plus feet.Hot burnin'10mm brass in his Face !
Funky thread title !
"Forbidden Knowledge about Hand loading" . on the second page of the reloading section. It has a ton of info about subsonic handloading.
Rob should pin that thread, its a keeper!
I could only imagine they want to compare themselves with the likes of Hornady,Remington,Winchester or any of the large established manufacturers that they are NOT !
