1/7 twist. Range of projectile weights. All brass case as steel is just for AKs yo.
What's your take?
Got some recipes, camera died though. Spent all my money on dog care and guns though. Which I do not regret.
Damnit guns are fucking awesome. (Looks at FALs longingly)
My CAR15 is something like 10.3 or 10.5 and it's handy in tight spaces, but ballistics beyond 200m is crap. With that twist rate you'll want to pair it with 75gr OTM or 77gr SMK bullets. 55gr loses a lot and M855 just sucks all around.
As the years wear on I think I'm kinda with Clint Smith on the fact that "God and Eugene Stoner got together and decided that a 55gr projectile was designed to go through a 20" barrel". I'm wanting to build a "modernized A1". I've got the LMT lower and furniture from brownells. But looking for a C7 upper and doing research on a 20 pencil barrel with 1/8 twist.
