Kral Jumbo King edition

I'm building my benchrest rifle for Arizona. It's a Kral Jumbo King edition. Play on words, you could say I'd like to steal the crown 👑. I have a Lothar Walther polygonal rifled barrel in 25cal and just waiting for the gun to arrive next week. The barrel is 23" and should shoot the JSB Heavy 34gr at mid 800's with my valve tune. 



Can't wait to get this thing shooting. 
 
Yeah, beat the crown

"JimNM"Just for argument sake, will you shoot it the OEM barrell for a benchmark verse the LW?

I understand if you are under the gun for time...however, it would be nice to see so.e before and after modified performance photos.
I will be shooting both barrels for comparison. I expect the stock barrel to be a great 1" gun out to 50 yards but I'm looking for better groups at further distance. The stock barrel is getting machined to turn my Beeman Chief in to a .25 squirrel gun.Â
