My first break barrel was a Crosman Nitro Venom .22 cal. It was a tack driver right out of the box and still is today. My second rifle was a BSA GRT Lightning .22 cal with only a 10 inch barrel. Also a tack driver. (This is an accident but read on) My last purchase was a BSA GRT Supersport with a 18.5 inch barrel. Identical to the Lightning except for barrel length. I assumed (and wrongly so) that the longer barrel in the same gun would do better yet. The gun had so much slack in the hinge assembly that a 4 inch group was the best you could hope for. I peened the hole in the barrel piece to take up the slack and cut the barrel down to 12 inches and finally got a decent shooting rifle. (The shorter the barrel on a break barrel rifle the less any slack will affect the trajectory) I find it sad and inexcusable that a $150 Crosman has a better designed hinge with a larger pin you can tighten that a $400 BSA. Live and learn. Good shooting!
