Finally got out to test the first barrel from Mike @
https://www.manzellaprecision.com/ . The machine work on these barrels are excellent. Amazing fit and finish. The thread to receiver fit is perfect, no wobble when screwing the action on the barrel. Nice engraving on the driving bands on a chambered round and zero issues extracting a live round. High polished chamber and chamfer. No lead shaving after shooting 100rd...
It didn't disappoint! Started hammering from the first rounds down the barrel.
20" Bartlein M24
1/2-28 rimfire muzzle threads
22LR Match Eachus chamber
XLR Envy chassis
BnA TacSport Pro 2 Stage
Athlon Cronus Gen2 BTR
Shot from a SEB NEO
Here is the first 12rd down the barrel of SK+ to zero at 50yd. After adjusting zero with the first 4 shots, the rest shot into a nice clover leaf.
I then took an opened box of Center X that had 10rd left in it and shot 2 five shot groups. Top center first, then the left group.
I then shot these 4 5x5's at 50yd...starting with the top row and down row by row I shot 3 lots of Center X and then 1 lot of R50 across the bottom row....that 3rd line down, last lot of CenterX was really shining compared to the rest. Not a bad 0.292" 5x5 AGG!
We had rain coming, breeze was kicking up and it was starting to spit. Decided to shoot a few groups at 100yd and get out of there since the breeze was really starting to blow.
That 28554 lot of CenterX was really shining at 50 and 100yd! R50 performed better at 100 than at 50.
This is 3x5 of R50
Can't wait to get out and get some more rounds down this barrel. Especially at 100, 200 and 300yd. Very impressed with the results with 100rd or so down the barrel!!
I also have a 1.2" Straight GM 4140 20" barrel from Manzella to test next. Stay tuned....
