This looks interesting. Anyone have the inside story?

That may function in a certain .38 special converted 1911.....

Looks like the definition of "speedloader unfriendly", for a inconsecuential gain in burn efficiency...
Since I've never had any trouble getting accurate 38 spl loads for a snubby (at any power range desired) with normal powders and bullets, I fail to see the attraction.
Less powder to get the same speed should result in a (admittedly minor) reduction in recoil. Powder exits the barrel as either gas or unburnt particles. Mass leaving the barrel makes recoil via the equal/opposite reaction thing. I'm sure there's formulas to determine such things, but I'm not math-smart enough to go to that depth.
The formulas are here:

For a normal 38 spl load, the powder only contributes to about 5% of total recoil. If you reduce the powder charge 10% thanks to deep bullet seating, the overall recoil reduction would be only 0.5%.
I'm no SME by any means but:
Wouldn't the bullet's dwell time in the case now be increased, and as a result an increase in pressures, and/or an increase in pressure duration?

If anyone sees a broken image of mine, please PM me.
Looks like a reversed hbwc.
