Can a break barrel ever be as efficient as a sliding breech springer

[Barryg]

I think some of them are nearly as efficient, like the Feinwerkbau Sport and the Weihrauch HW55.

The first sliding breech was an Anschutz target rifle from the 1950s

Feinwerkbau brought out the FWB150 which soon morphed into the 300, while the Commies produced the Haenal 312 match rifle. In terms of non-match rifles there was the Chinese Lion, and even Relum had a nasty little side-lever.

The HW77 was a very late sliding breech gun, but the first quality full-power sporting rifle with this configuration. The 77 sparked the modern trend for sliding breech rifles. The main things about them are that they fix the barrel and the scope together rigidly and the pellet is seated directly into the bore so there is no jump like in a tap-loader.

Thanks I had forgot about that thread
I think that the sliding breech is a clever invention, I wonder why they don't make break barrels with shorter transfer ports, I think that old BSA cadets had short TPs.
