MiniMag Chrono Testing Results

[Walker]

I was tired of being inside, and decided to rebuild my old 3k FlatLine and run some chrono tests.

Flatline reg rebuild - Quite easy really... First time for me...

https://www.mcarterbrown.com/forum/paintball-news-aa/ask-the-experts/1065-agd-flatline-rebuild-guide-56k-beware

Tank setup: 68/3000, Flatline reg set to 850psi output, not changed during tests.

Gun setup: Classic MiniMag, level 10 bolt, benchmark frame

Ammo: Well used reballs

Chrono: Master Shooting Chrony

Barrels used: 16" SmartParts, 10" J&J brass, 11" Modified Crownpoint, 11" unmodified Crownpoint, 11" Bull, and a stock 8" MiniMag barrel. (ID measurements take at the bore end)

Shot strings: 10 rounds over the chrono

Shot tempo: Drop a ball in, line up over chrono eyes, shoot, repeat...

Excellent. Many thanks!

[DarkApollo]

Awesome! Ive been trying to rebuild mine but I can’t get it off the dang tank!

Interesting that the stock barrel had the best std deviation. Did you use the same 10 reballs for each test?

[Walker]

No! Why didn't i think of that! I should have used the same ones!
