I do some deepseating in several cartridges, for the usual reasons. You list some additional advantages I'd not been aware of. Thank you.

I've shot a friends 329PD with his 300gr "bear loads". It's a handfull, but fairly controllable. Follow up shots are slower. I think with a 900fps .44 special load it'd be fun. Load .44 mag cases with the 429421 & 8-1/2grs of Unique & you'd be there! It'd be an easy packing, powerful six-gun. I liked it.

Groo here Bradshaw ,,, Sir.. The idea of deep seating to move the peak pressure back is one I never though of. Other than at longer range, would not a Full WC do the same thing??? I went the other way with GT's 190gr SWC HP but crimping OVER the forward driving band would do something similar[??] Please expounde on this.

I went the other way with GT's 190gr SWC HP but crimping OVER the forward driving band would do something similar[??] Please expounde on this. ***** Groo.... way I look at it, many of the early cartridges were DEEP SEATED. Even some of the newer black powder cartridges, .45 Colt, .44-40 and .38-40 to name a few. Wadcutter target .32 and .38, most of it deep seated. Figured I stood good ground when, as a teenager, I started my hand loading of .357 Mag, .38 Spl., .44 Mag & .44 Spl., with deep seat cast and swaged semi-wadcutters. Never looked back and still don’t. If I have a pet load for the .45 Colt, it is a cast 335 SWC Plain Base, deep seat over 10.9/HS-6. Plenty of oomph, good penetration, blunts well on meat, with a noise signature o.k. for use in the barn when necessary. In designing the Bradshaw-Martin 194 SWC GC for the .357 Maximum, I wanted the longest ogive possible, and that was made possible by positioning the front band about .030” below case mouth. This, in an effort to drive COG (Center of Gravity) rearward----get COG away from COF (Center of Form). A hoped for benefit is to hold peak pressure rearward, while boosting Ballistic coefficient. Can’t describe the pressure picture, but the little cannon feels mellow in the hand, and the Bradshaw-Martin tracks like a mother. Is the GT 190 SWC HP a .44? If it is a .44, I certainly would try deep seating. Let us know how it sugars off. David Bradshaw

This is interesting and caused me to post, rather than just lurk.
bradshaw, do you any pictures of some deep-seated .44?

PsTaN ***** Go to Gallery section, first sticky, All the Bradshaw Photo Volumes in One Spot (compelled by seancass) Vol. 2----M-29-2. Two favorite, and mild, .44 loads for 4-inch Model 29: * Cast 240 SWC, deep seat in .44 Mag brass over 5.5/HP-38 (HP-38 is Winchester 231 ball powder. Seat front band about .030” below case mouth & roll crimp. Standard Large Pistol primer. Mag primer fine if don’t have standard. Estimate velocity around 800 fps (somewhere sun notes from many years ago). Photos show goat shot @ 3-inches, and stainless steel milk separator shot @ 200 yards. From a proper revolver, load groups 5x5=4” @ 100 yards. * Cast 240 SWC deep seat in .44 Mag case over 10.6/HS-6. Same seating and primers as above. As I recall, his load clocks around 1,000 fps, depending on revolver. Groups a little looser, 5x5=5-6” @ 100 yards. * Not shown: Swaged SWC Half-Jacket (pure lead core), deep seated in .44 Mag brass over 17/Hercules 2400. 1060 fps from 6-1/2-inch M-29. CCI 350 mag primer (or other mag primer). Far more accurate than either of the above loads, and will punch a whitetail buck in the ribs like Joe Frazier. An M-29 lasts forever with this load and kills clean as anything close to its energy level. The same load with today’s Alliant 2400 should do just as well. The above loads should work fine in an M-69 or M-329. Holding pressure slightly rearward should also benefit in the 69 and 329. David Bradshaw

I see and am intrigued.
I need a load for my M69 and my mind wanders toward a deep-seated Bayou Bullet 240 SWC.
However, I only have Unique, 2400, and Power Pistol on hand.

Try 8.0gr of Power Pistol or 17.0 - 17.5gr 2400 deep seated and crimped over the front drive band of the Bayou 240gr SWC - OAL approx 1.503"+-. Use magnum length brass and standard, not mag primers. The power pistol load should run in the 950 + fps and the 2400 should be 1,150+ fps both from a 4 1/4" M69 (50 to 100 fps slower from a 2 3/4" - depending upon the indiv gun/load).
Good luck,
Paul
