I just think it's great that all your neighbors came over to admire it, and not to threaten calling the cops on you. :)

I am 6'2" and 200lbs it would take quite a cannon to be too big for me!

Hehe... You're fat, just kidding!
Very nice cannon, and thanks for sponsoring Spud Files...

Dude that bracketry is badass clean in a sick way. I wouldn't be surprised if they sold a mountain of those things alone as DIY kits. Include a dovetail somewhere or something like that and BAM! Instantly it becomes the ultimate DIY bracketry kit ( well it already is). I don't see an advanced combustion kit topping this one for a long time to be honest, because SIZE MATTERS HERE! I love to see class work on this forum. It makes me smile.

Dude seriously

1) wrong thread to ask in
2) learn how to write
3) you gave no info on location, age and so on
4) your making crap posts all over

Read and for christs sake search, or dont waste our time here.

Wow! I haven't been on this site in a long time! Spud gunning is real expensive in NZ blah blah blah, you've heard the story.

That is HUGE! $1000 bucks though, USD even. I would love to know how the meter works... I'm sure some of you engineers could figure something. I think the screwing and unscrewing the cap would be annoying? Easier than shoving one down the front?

Micro, check out this thread on the metering device... http://www.spudfiles.com/forums/viewtop ... tml#243202

maybe someone will post a video of a 60 inch barrel loaded with ramrod for cycle time comparison.

That is an impressive cycle time, even if it does seem a little rushed in it's execution...
Does that thing kinda look like a big cat to you?

Updated:
The fully assembled 520 now comes with take down barrel and new muzzle brake and CONCOA regulator. The photos below are a model for the local gun shop. This includes 2 barrel length variations. The shorter barrel totals 50" when assembled and longer equals 65". The Chamber is small (shorter) than the original and C:B ratios are now 1.22, 1.33 and 1.59 for short, normal and long.

Slip fit Couplings for 1.5" and 2" and Muzzle brakes in 2" will be posted on the web site tonight.
