Nelson/Marvel barrel upgrade.

I got a 2" diameter barrel blank for 22LR from Lilja to make a few one piece conversion barrels. But I see they have a tight bore barrel with 6 groove, .2215 groove diameter and .2200 bore diameter in 1-15 and 1-16 twist standard diameter. That's getting near Hammerli specs. So as to offset the cost to try it I'm wondering if anyone would want their barrel re-barrelled with 3 of the length leftover. I'm thinking $275 that includes shipping. Yes if more want re-barreling I can get more blanks at the rate of 4 pistol barrels from the blank. Delivery time for the barrel from Lilja is 12 to 14 weeks.

 Let me know if your interested.
