Also agree on the adjustable gas block. A friend shoots a 6.5 ar10 and uses one. I think he shuts it off completely when working up loads.
Ive been too broke (too lazy) to actually start reloading but I’ve read good things about:
Lapua brass - expensive but very consistent, lasts a long time. Read about starline rifle brass. Starline makes good pistol brass but I read the rifle brass was not that good...yet
(May have been a lower priced starline brass, not the one your using)
Redding seating dies - produces very concentric reloads
Foster shoulder bump sizing die - I believe it neck sizes and shoulder bumps. This may not apply to a gas gun. I think my friend always full length resizes for his 6.5 ar10. He also anneals the brass every time he uses it. He also crimps in cause he has to ever run it semi auto.
Hornady concentricity tool - Mrgaf likes hishttps://lockedloaded.com/product/jrtxb382
Redding instant indicator with gauge - mounts on your press and lets you quickly check reloads. YouTube it. It can check a lot of things.https://www.brownells.com/reloading/measuring-tools/case-gauges-headspace-tools/6-5mm-creedmoor-instant-indicator-prod95375.aspx
Sinclair or Hornady bullet seating depth gauge - for Hornady you can send them a fire formed case and they will tap it so it can be used with their system. There are also DYI methods on YouTube. Basically, all are to help the bullet being a consistent distance from the lands (CBTO) vs having a consistent OAL
Redding turret press
Foster coax press (“floating die” for better concentricity) - for regular presses some people just put an o ring under their dies to help it “float “. Saw it on YouTube - 6.5 guys
Powder - if your hunting, I read something about some powder being less sensitive to heat. Because of that the guy also didn’t use a shoulder stock shell holder. I guess it is hot where he hunts and ammo/powder would change temperature a lot if exposed to the sun
Bullets - I forgot which ones. But certain brands are a bit more consistent in weight, concentricity, etc
I just ordered a Tikka in 6.5 but I’m lazy so I’ll probably just buy ammo and the Hornady concentricity tool
Curse you Mrgaf...see what your 7mm-08 has done!
