Benelli super sport prob

Having trouble recycling 24grm carts ok with 28s anybody having same problem 

Properly not enough kick in the shell what are you using !

Tried eley VIP and box of hulls both the same ,shot an all round today and a chap in the same squd has one and he's never been able to use 24s

Sometimes, you have to break them in a bit, with a few beefy shells.

Mind you, if you use a soft 28g, you shouldn't need 24's

Thats one of the problems with inertia systems - they need a minimum force to activate. Its the initial 'thump' that stars the cycle. Unlike gas systems which can be regulated to shoot anything.

I had the same problem with both my Sport 2 and Córdoba. Benelli's are notoriously finicky In this regard. The simple solution is to shorten the recoil spring approx 1 1/2 inches which should allow all 24 grain loads to cycle. It is a bit Heath Robinson but does work well .The alternative is too order a Wolff reduced power recoil spring from Brownells U.K. (£10 ish) which will cycle in my experience Gamebore Evo & Blue Diamond 24 loads but has still too much resistance for Express or Dan Arms to cycle 100%. Hope this helps
