Picked up a new mold for the 45 AR from LBT. Put most of the weight in the nose to give more powder space with a large metplate (WFN). Weights in at 245 grains and should get around 1100 fps without pushing it real hard. Now if the weather would just clear up and I can get out with the chronograph.

That's a great looking sixgun and a really effective looking bullet. The 45ar is an excellent little round and deserves its own bullet. I like how you've maximized case capacity and given it a good wide meplat.

Be sure to post results from a chrono and the targets.
I know another fellow who has ordered a similar mold from Mountain Molds and has tried the same thing.

I have considered something simular, but in the LFN style. I would also get one of my guys to HP one of the cavities....
Still, its quite interesting. An range results update would be appreciated.

I loaded 7 grains of Universal Clays and 10 grains of AA #7. The Sierra manual has a section for the 45 ACP revolvers and relied on that to a large extent. I find I really enjoy the 45 ACP revolvers and decided as well that it just needed its own bullet. I'll report back once I get to the range.

Standing by to hear about your results. That is a nifty bullet. Congrats on your heads up thinking!!
I have several 45 acp revolvers myself. Lots and lots of fun!

What is the size of the body and nose? Why the gas check? Not any criticism intended, just looking your thinking.
Should be enough room in the case for a healthy does of 2400 without jumping pressure to the sky. 8 grains of Unique or a smidge more will also get you where you want to be.

I think AA7 is thinking right. The slower powders will need more bullet pull than you have there. Most of what is in the case neck is lube groove....
Unique, AA5, etc might be the best for the job. Stay away from Magnum primers...

If that fails to please you, you can always send your cylinder to Clarks for a 460 Rowland conversion. I have Verals 230 LFN for my 45 ACPs, so far, it's the most accurate cast bullet Ive tried in my 1911s

Brushpopper, nose is approx. .4 and I size them to .451 as that is the size of the throats in my 2 625's. I use gaschecks on everything. I think they offer a number of advantages and find the cost and effort quite minimal. If I'm wrong they at least give me more confidence in the quality of my bullets and they certainly do no harm. As to the 460 Rowland I rechambered a 45 ACP cylinder for a Bisley to 460. I figured that was a better platform for the Rowland rather than a S&W. I have the same LBT 230 LFN mold and really like that bullet in the 45 ACP. I used it over 7.5 grains of True Blue and get around 900 fps with excellent accuracy.

Made it up to the range today and used the 625 pictured above as well as a 5" Performance Center 625. Both have throats that measure .451 and that what I sized the bullets to. All loads used R-P brass and Federal 150 match primers. All velocities and standard deviations are the result of 10 shot strings using a Oehler 35.
7.0 Universal Clays 5" barrel 882 fps SD-26
7.0 Universal Clays 4" barrel 860 fps SD-27
10.0 AA #7 5" barrel 772 fps SD-6
10.0 AA#7 4" barrel 755 fps SD-12
8.3 V 3N37 5" barrel 895 fps SD-18
8.3 Power Pistol 5" barrel 933 fps SD-11
8.3 Longshot 5" barrel 930fps SD-18
8.0 WSF 5" barrel 957 fps SD-8
8.0 WSF 4" barrel 934 fps SD-25
None of the loads showed any signs of pressure. I didn't have my camera to show groups but accuracy was more than satisfactory. I would also like to try Unique and Winchester Auto Comp. A lot more to do but a great start and I'm extremely pleased.
