Gamo Coyote .177 problem
« on: March 23, 2018, 01:07:15 PM »

Hello, I´ve a problem with my gamo coyote .177 PCP...and I hope someone can help me ....I need to understand and solve the problem..
muzzle velocity 264 m/s     constant..
spread 5/6 m/s  between 232 BAR and 100 BAR
pellet  HN Barracuda match 0,69g/10.65gr
target at 25 mt
accuracy excellent around 150/160 BAR....pellet on pellet....
If the velocity is constant why the gun doesn´t maintain the accuracy allways ?????

Have you tried JSB Exact Heavy 10.3 grain pellets? I suspect the barrel may not like the H&N Baracuda as much as the JSB's.

I´ll try again, but until now HN barracuda 4.51 are the best..

HN barracuda is similar to the Bisley Magnum .....and the BSA barrels likes BISLEYS...

Every barrel is different, not every BSA barrel likes Baracuda/BisMag, I would try some JSB Exact Heavy 4.52mm to see if the grouping improves.
