: Gamo shadow tune up progress
: Magnum July 31, 2009, 04:06:53 PM
Well finally a full tune and its all back together with new maccari e3650 spring, a telsa seal and a GRT 111 trigger... thanks to support and good help from gta friends, no parts left over lol:) It looks good so far and thought  I would share first results .. its late so only fired about 35 shots 15 to sight in and 20 on target to compare with target shot before starting  my tune up. Both targets where shot identically (5 shots at 5 targets) using arm on a rest and holding the front of stock no back rest. I will try further pellet tests and a chrony check on the weekend.

Magnum,

Great work!  Doesn't seem possible from such an inexpensive gun.  But then again I think the spring and seal was about $30 and a gold trigger at $32?

I got similar results with the E3650 and Apex seal.  Here's a picture from a previous post showing a 20 yard shootoff between my TX200 and my Big Cat.  At 1/3 the price the BC holds its own.  TX on left and BC on right.

Super Job Tony. Isn't it amazing how much better a tuned and triggered rifle can shoot?!?!?!?!? Those before and after target pix are  just another affirmation of why tuning springers (most low-end rifles) is a neccesity for consistancy and accuracy. Congradulations!! tjk
PS How's the spring look now??

The springs looks great now thanks tjk:) ...  I believe its shooting better with every shot but hard to tell such small improvements now when all bullseyes lol:) So glad I did a before and after target. I still need to chrony it and I will post those before and afters too.  Oh and good job Andy on your bigcat:)  Tony.
