Lothar Walther for .25cal slugs

I think the more important aspect here is the bore uniformity. I would take a barrel without a choke. However, we need to be sure that the tightest part of the bore is at the muzzle. There is no barrel with the exact same diameter throughout the entire bore. The best barrels have the uniformity of about 2 microns. Other aspect is the barrel twist uniformity.

I machine a couple barrels for my Impacts then swear I’m done. Then ideas start floating in my head. Months go by and suddenly I’m $1,000 poorer and back at my lathe. I just got done with another .25 last week and will be doing one more two weeks from now. After that, hopefully my ship comes in and I will get to build another .22 barrel. Then I will be sick of it but hopefully happy and swear I’m done again. I will only offer one thing. What Seeker says in his first response is priority. So how can you as a consumer control how true your barrel is? You can’t. Unless you buy 20 at a time and gauge them. So, you decide to play it safer and order a barrel with a crutch (choke). Then you can start to experiment with choke reduction. And we have to start another topic about that.
 
Yeah, I know that feeling.
The crazy thing is ideas wouldn’t float in your head if your gun was truly great. Conflicting that is my guns are way better than they were with the multi piece FX stuff on them. But the FX stuff was capable of very small happy groups on its good days. So if you step back and were able to look at yourself, you might appear insane. So I just define it as the hobby within the hobby. And viewing from an outsiders perspective, throwing money and time in the toilet.
