Thanks for the confirmation !Just to confirm that compared to any 21g load I have shot, the 26g litespeeds are significantly harsher/punchier. As I said right near the top of the thread, recoil was (maybe unsurprisingly given the 2g difference) not dissimilar to a 28g fBlack. My other half, who shoots TT21s, tried one litespeed for a longer target and said 'never again' due to the recoil.
As ever YMMV; it's all dependent on the individual and the gun being used.
I'm a casual shooter and personally find the litespeed gives me similar confidence/results as fBlacks for a significant discount. That allows me to forget about cartridges and enjoy myself whilst saving some cash. If I was to shoot competitively in the future though... I'd probably pay the extra for fBlacks
As an 11 stone weakling and very recoil sensitive. it sounds like I will steer well clear.
