I kept seeing exploded bolts in threads on other pages from a few years back. I think these were first passes of machined out 556 bolts. I know some new steel has been used but does anyone have more details?

Not just new steel. Better bolt designs as well.

What barrels are guys using?

The saturn button line gets so much love and hate hard to know what's up. The 18" medium contour is a screaming deal if they shoot well....

I'm shooting a 22" satern with the Grendel ii chamber so I can load the big pills. 140gr nosler partitions put a hurt on whitetails.

I shoot a 20" Saturn. It's shoots great, but took a little while to settle in. I've shot it out to 800 yds on 2MOA steel with 123 Amaxs and Nosler CC.

JP uses Lilja blanks and we all know how good both of the companies barrels are. I built a 6.5 Grendel with a Black Hole Weaponry Poly barrel. Shot in the .6's and sold the upper to a friend. I could not get that upper back if I begged him. I think it was around $900 when I finished it.

You can usually buy just the barrel with matched bolt from JP. Their upper wasn't quite perfect for me, so I built a slickside bare upper (which I'm now converting to side-cocker) with JP 18" Supermatch barrel/bolt and adjustable gas system. Then finished it off with an AP 17" carbon fiber handguard, Ace stock, nickel boron carrier, Tubb buffer, etc. The rifle weighs in at a dainty 6lbs and can shoot with the best of them. I shoot it as a Highpower spacegun and as a 3-gun rifle and never feel outgunned. Pic to come. Oh, and it was not as pricey as a direct JP, despite the $630 barrel/bolt.

Is this a 6.5 Grendel or 223 Rem?

It's a .223, but my point was, build a "JP" the way you want.

I shoot many 6.5's, and the 6PPC upon which the Grendel is based, but I've never had the need for 6.5 Grendel. I'd rather do a 6mm variant from an AR.

Thank you very much for the clarification and your other thoughts on caliber.

I've been kicking around the idea of remaking a receiver set into either 6.5G or some 6mm variant (6mm AR, 243 LBC, or 6x6.8mm, to name a few) for longer range Designated Marksman type matches.
