Thread: 303 reloading with lighter projectiles

In my experience that doesn't always work out too well, as the bigger case volume alters the burn profile of the powder maybe the dacron filler will work. In my early days of reloading I thought to make some 110 grain loads for a 3030 and used the load that worked fine in my m1 carbine. Surprisingly thumpy, case ejects with a little effort and the primer falls out. Fired one more then pulled all the rest and reloaded them with 3031.
