35remington;
You will get NO guff from me for safety cautions.
One of the reasons I specifically stated "NOE 454424" is that Lyman from time to time has changed the design of the Keith bullet drastically. Casual looking, the different bullets often look the same but the seating depth is materially different. There was an excellent article in one of the major gun magazines that showed a couple of Lyman variations.
It is quite possible that my NOE bullet is materially different from YOUR version of the Lyman 452424.
Again, this is a good reason to ALWAYS question third party accounts.
Again, Lyman cast bullet data and SAAMI have materially different pressure limits for the Auto Rim case and the .45 ACP case even tho' they have essentially the same capacity. This is simply because the Ammunition Companies have always loaded the Auto Rim with soft lead bullets (swaged) and got serious leading if they drove them faster.
A good cast bullet can be driven the velocities that I have reported within proper pressure limits (the revolvers easily handle +P .45 ACP loads) without any suspicion of leading. Shoot those same loads with lead bullets furnished by the ammo companies and you have horrible leading. Been there and done that...
Stay safe, folks.
Here is a page from the Lyman Cast Bullet book:
I would caution anyone reading this to NOT try to use this data in a 1917 revolver. The cylinders were not heat treated. The loads should only be used in S&W and Ruger revolvers made after 1950 or so.
Thosands of shooters have used these loads without issue.
