I've had two Brown-Whelens both 23 in. barrels.Wore out the first barrel doing load development and have tried every load combination under the sun including the new wonder powders.Best velocity with 250 gr. Bullets was 2620 fps,this out a Lilja SS tube. The Brown-Whelen is a Gibbs type improved version that theoretically should do better than a standard Whelen,mine obviously hasn't gotten the message.
