I suppose. I got the barrel back today and I think I'm happy with it as-is. Lotta effort to flute one barrel.If he can machine it down would there be enough to also flute it?
To YOUR KNOWLEDGE which are the best pellets or slugs to use in the HP MAX .50 cal?Took er to the range today.
I've learned a bit about how the barrel is performing:
JSB pellets, hades and regular - terrible.
NSA 79gn .356 and .357 - not great
NSA 93gn .356 and .357 - not great
NSA 108gn .356 and .357 - a little better
NSA 125gn .357 - best so far
This is 100yds. The 5 left-most shots are NSA 93gn .357. Group on the right is NSA 125gn .357. Both with a regulator at 250 bar.

There were some strong gusts on the range today. Not sure how much that had to do with these groups though.
I'm thinking I need to try some longer/heavier slugs. Gonna order some more NSA 125s and NSA 142s. Any other slugs you guys think would be worth a try? The barrel is spot on .357 btw, so I'll stick with that size.
@caliusoptimus Nice thread. Thanks for taking us along for the ride. I have a question for you. It’s difficult to see in the video, but when the bolt is cocked and out of the loading slot that you milled (bolt handle up), is the probe protruding slightly into the breech preventing you from inserting a magazine?That was worth the effort. For sure.
Yes, the probe is protruding a bit unless the handle is pulled back farther and locked into the second notch.@caliusoptimus Nice thread. Thanks for taking us along for the ride.

It's advertised as .357 with .351 lands. Of course I'll measure to know for sure.@caliusoptimus 0.368 down to .3585 is a significant difference on your leade. What’s the groove diameter on your incoming TJ’s barrel?
