I wanted a powerful 100-yard, mid-size game defensive load that would complement the 460R pistols I plan to carry on all-day treks. While commercial loads are available from folks like Buffalo Bore, Cor-Bon and Underwood, they are chronically out. As for components, the Speer 4481 JHP and 4484 DCHP are both viable candidates but even these are gone everywhere. Nada.
So I started to look around for molds that would give me the following:
1. A true-to-Keith profile with 3 equal driving bands that is 250+ grains and with expansion possibility
2. 1100+ fps MV from a 460R case without powder compression or over-pressure
3. A nose/ogive/leade/shoulder that would reliably feed in a 1911, M&P or Glock
In other words, this is a mid-range 429421 load for autoloaders that carry more than 6 rounds. Although I already have a couple of Lyman 452424 molds, they do not provide the above. So I reached out to a few guru's and honcho's on the forum and got some quick and helpful replies, but alas no solutions without waiting for many months, or even more expecting the next GB.
I wrote Tom at AccurateMolds.com and Erik at HollowpointMold.com. I saw the many options in their catalog but although some were close, none really met all three of the above criteria. Tom wrote me back quickly and Erik called me on the phone and we had a great chat. Over the course of a matter of days, we came up something pretty cool.
Tom drew a new design and it's now in his catalog - the 45-265K - that is a true-265 grain Keith that has an OAL of 0.685. This leaves the ideal amount of room for powder with an COAL of 1.250: up to 10.4 gr of Power Pistol or 13.6 of AA7 for a MV of about 1150 fps.

With 15 gr for hollowpoint cavities, the 250gr weight will fly a little faster at between 1160 and 1180. Erik is ready when initial testing is finished to devise his inset bar conversion and he mentioned he can vary his pins to reach a specific target weight. Looks like we are good to go!
As a noob to this forum, I am really impressed with the friendliness and support of CB members. I hope this foretells the success to come, and I thank everyone for being so supportive and encouraging, as well as living the values of openness and innovation.
Let the journey begin!
