So i shot the 601 for about a month and ran it over the chrono this evening, all looks about right.

3 x 10 shot strings from cold.
Average speed 593fps with H&N Excite Econ II pellets (7.4grains), 5.78ft/lbs.

Decent pellets could only improve consistency.

I did have the front weight fitted for a while but had to remove it, still felt very unbalanced so last week i cast a few weights for the stock and it feels much better now, i might even want a little more but its ok for now.

288g in the cheekpiece


and another 335g in the stock


Last job was adding a few baffles which turned out great, it's really very quiet now



Does anybody have a 602 or 603 with the dry fire feature ?
