B525 LIGHT Posted June 18, 2018 Report Share Posted June 18, 2018 Have just noticed Gamebore have changed the packaging on their Mamoth Steel lines but according to their website they’ve increased the muzzle velocity too. Quote Link to comment Share on other sites More sharing options...

B525 LIGHT Posted June 18, 2018 Author Report Share Posted June 18, 2018 1460fps Quote Link to comment Share on other sites More sharing options...
figgy Posted June 18, 2018 Report Share Posted June 18, 2018 So gone up 10fps nothing to be too bothered about. Johnnys testing shoes them to be close to the published speed so a decent shell at a reasonable price. Quote Link to comment Share on other sites More sharing options...
