Last night I found my copy of the SPG lube loading book. According to the information there, the only 2 1/4” .40 cal is another bottleneck .40-70. The .40-70 Govt (as developed by Dan Phariss of Shiloh Rifle Mfg) is a 2.1” bottleneck, .40-70 Sharps Straight is 2.5”, .40-90 Sharps is a 2 5/8” bottleneck and .40-90 Straight is 3 1/4”.
