Hello everybody! This site is great. I've learned a ton already, and there is much more learning to be had!
I've been casting and loading for a few years. I recently purchased a Springfield Mil Spec 1911.
I've been searching the web for information as I develop a load for this 1911.
I have about 8 lbs. of Ramshot Silhouette. Apparently it is close to the same stuff as WAP. I have read conflicting accounts regarding its use for 45 ACP. From what I understand, it is a good powder for pushing higher velocities.
I ordered a Lyman mold, the 4542460. The Lyman handbook suggests an OAL of 1.161". This thread suggests an OAL of 1.175" to 1.125":
http://castboolits.gunloads.com/archive/index.php/t-46622.html
Here is the Ramshot Silhouette load data:
Bullet: 200gr Lasercast SWC, Lead
Start load/velocity: 7.6gr @ 964 fps
Max load/velocity: 8.4 gr @ 1,071 fps
Max Pressure: 20,349
OAL: 1.267"
I am trying to determine a safe OAL for this powder, as it may generate higher pressures. Can anybody suggest a safe place to start, regarding the OAL? Also, will the hardness of my alloy be more critical with these higher pressures and velocities? I have read that alloy for 45 ACP typically does not need to be very hard.
My intention is to develop a load for practice/plinking.
It would be nice to hear suggestions! I could always purchase a different powder, but it would sure be nice to use up the Silhouette that I have on hand.
Happy thanksgiving everybody!
