Thread: 577-450 case forming

So the numbers on case volume are

577 Snider case water capacity

Bertram new brass 120.0 grains

Magtech 24 gauge formed Snider 134. grains ( so plus 10% volume on the Bertram )

Kynoch vintage 122.5 grains ( this is a fired case and will have increased volume on new )

So as @rambo-6mmrem mentioned a lot more case capacity and care and filler required with both the 577 Snider and 577-450 formed with Magtech

On the up side you will have no trouble loading a full charge of BP into these cases and still have space for a grease cookie etc
