i use a regular carbine spring with a light buffer (1.8 oz) so that it cycles everything reliably. Recoil is minimal with supers and feels like a .22 when shooting subs.
I dont get it. What does a black guy know about wokking a dog, much less a portugese water dog? <laughs>
...and besides (for the birther conspiracy theorists out there), dog meat, like pork, is not halal!!
I use these. They work great. I mount the shellholder in my drill press and it takes only a second to trim each cartridge. Everything ends up the same exact length.
These do leave the cartridge length a tiny hair longer (my target length is 2.005") so I fine-tune the case length (shorten only) by gently filing/sanding down the tip of the case length gauge a tiny bit at a time. Cheap to replace too.
300 AAC ... just sayin'...... <laughs>
There are differences in 308 LPK's. The 308 receivers all use longer takedown pins but some are longer/shorter than others. If you're sticking with the MEGA set, then any DPMS LR308 compatible LPK should work. No big concern on the brand - just compatibility, since there's no real standard in the 308-AR world.
That said I do have a couple CMMG 308 gunbuilder (i.e. LPK without trigger) parts kits available. They are DPMS LR-308 compatible.
