I'm guessing the benefit of deep seating is increasing load density???

ProGun.... HS-6 seems relatively impervious to air space. Deep seating yields same velocity (as same bullet conventionally SEATED) with one-to-two grains less powder. And, as a matter of conjecture, deep seating may hold the pressure wave back for a moment. Some folk like the look of a big ole bullet hanging out of the case.
Deep seating yields excellent accuracy from slow (magnum) powder at below full house loads. David Bradshaw

Hmmm... I may have to experiment with deep seating a 270-SAA atop H110/W296 in .454. Although, I do like a big ole bullet hanging out of the case. However, I'll have to do some more reading. While I don't have any HS-6, I do have Unique, Universal, Titegroup and Green Dot. I don't know how they react to change in load density. I don't want to inadvertently turn them into Bullseye by taking away too much space.

Remember, deep seating predates anyone writing on this forum. While I prefer the efficiency, without ACCURACY none of my ammo would be deep SEATED. As for the .45 270 SAA deep SEATED over 296/H110 in .454 Caull brass, I suspect it to work better than the same bullet conventionally SEATED to crimp in the crimp groove. Note: Dick Casull accomplished his mission to build a high velocity forty-five. A hollow-pointed 280 grain Semi Wad Cutter seems on the face of it a wrong choice to push the velocity game.

ProGun.... were I limited to the .454 Casull cylinder in the Freedom Arms Model 83, DEEP SEATING for light and moderate loads in .454 Casull brass would be a major focus of the handload. Nearly all ".44 Specials" fired in my .44 Magnums are reduced loads DEEP SEATED in mag brass. The same is not true of .38 Special fired in .357 magnums. However, over the years I have loaded a great deal of moderate .357 Mag by DEEP SEATING in mag brass; as opposed to loading hot in .38 Special brass.
POWDER COATING may reduce fouling from firing .45 Colt in the .454 Casull chamber. Without the need to stoke Colt brass in the Casull chamber, haven't specifically tested this. If I had beaucoup Colt brass, yet very few Casull hulls, powder coating might demonstrate a whole 'nother advantage. David Bradshaw

Ingenious. Will experiment and hopefully share some results/finding in the future. I'd think for starters, one could seat .10" deeper in Casull brass and use .45 Colt loads. Not sure where that will land geographically on the bullet (270 SAA). Perhaps right smack in the middle of the front band...

Crimp always where it does the most good with the least distortion. Deep seat enough to avoid distortion of front band by radius of crimp or case mouth. David Bradshaw
