Gentlemen,

the 11,2x72 Schueler can be regarded as the equivalent of the 404, but with the odd bullet diamater and the unusual case with the rebated rim it is a piece of history.

58cm barrel: I load for the 11,2x72 Schueler (new buildt rifle of Harald Wolf) the Rottweil R907 powder and can obtain more than 700 m/s with the Degol 400grs SPRN and FMJ in a 65cm barrel. A shorter barrel with 58cm should be close to 680 m/s (recoil is another story...).

@ Jim:
Wim Degol in Belgium has a 400grs bonded core SPRN and a steel-jacketed FMJ in his standard bullet program.
Additional a 330grs SPRN for the 11,2x60 Schueler (not Mauser M71!)

best regards
Rolf
