so now we have plenty of 6.5 grendel replacement bolts available with no delay. so what would your opinions be on the best to the not so best without reguard to cost. this post is also to help folks who are lurking find these bolts so be sure to reply with a way to find the site to order the bolts you are going to be fond of. be sure to give a few details of why you like your choice. thanks!
I've had my hands on most of them except for the AA Hard use bolt, so far I like the Precision Firearms bolt. I would really like to try an AA bolt with the IonBond DLC coating (hard use.)

IMHO
1. AA hard use bolt
2. PF bolt
3. AA regular bolt
I have all of these...plus a couple supplied by Satern.
ETA: PF does some extra work on their bolts to polish them up...

AA Hard Use
JP Enhanced Bolt
PF/Maxim Bolt
Underground Tactical Bolt
All of these are high grade 9000 series alloy. I haven't put my hands on the new JP bolts yet, but JP makes products that have never let me down since 2003. The AA hard use bolts have the nicest fit, feel, and finish that I've seen so far.
My AA regular bolt is going strong after 5 years of use, and I shoot in volume. Most of my range sessions involve ~100rounds, some more, some less.

Same here. I've got thousands of rounds down range since I started, and my original AA bolts have never quit or been a problem in any way.
I originally didn't comment, because I've never used anything else.
The only thing I've ever been able to break on a Grendel is one extractor. It was in my 10.5" and had been used full auto, suppressed, and absolutely filthy for a very long time. I have a pack of spare extractors, and keep a spare bolt in the grip anyway. I expected to break more by now but never did. I'm quite happy with AA. I did grab some "Hard Use" bolts to throw with the regular ones in the spare parts pile, but still haven't needed them.
If somebody makes somethng better than the AA bolt, I've never had the need to find out.LOL

Do you guys notice the Maxim's tearing up the brass? Seems like the extractor is really sharp and gouges the rims pretty bad. I have some pieces of Lapua brass that have only been fired three times and they are chewed up.

That is why we hand deburr and polish ours. You can do it too with a dremel and polish wheel.

I have visually inspected both when new and after firing, measured (dimensional), and shot them all.
My personal favorites are:
1. JP enhanced bolt
2. ARP superbolt (no longer sold)

Yep, they do.

I have the following and have used two of the three of them hard with no issues.
AA in an AA factory 20" upper
PF in a Lilja barreled build
Underground Tactical: this is a spare right now although it could grow into another upper.
