I still have in mind to buy another .50 cal barrel (either another 24" Deerstalker or 28" Trade Rifle) for my Lyman so that I can have it reamed to 28 ga.
According to Lyman the .54 cal barrels have a max charge of 90 grns (3F) or 110 grns (2F) with a 450 grn conical.
To my mind I don't see why I couldn't load up a one ounce shot load with an equal volume of powder (it should be under the max charge as someone had shown me a chart stating such).
However I'm told that a 28 ga just will not do any more than the original BP loads devised by the British which gives 3/4 oz shot with 55 grns (2 drams) of powder. Their load for the 16 ga was 1 oz of shot to 75 grns (2.75 drams) and seems within reach to me.
Can anyone explain why this wouldn't work?
