45 Colt and 235 gr Flat Base Bullet

Doc.Holliday · January 12, 2013, 11:46 AM

Hi Folks; I see where Magma Engineering has a 235 gr RNFP bullet with a plain base.
Has anyone in this forum used bullets from this mold and would you call this bullet weight light for caliber?
I'm thinking of feeding this round into my three 45 colt chambered rifles for both plinking and hunting. This particular design also has a crimping groove. It seems particularly difficult to find a bullet with RNFP; crimping groove and plain base.
My usual bullet is a 250 grain RNFP BB and I'm thinking on a better bore seal with this plain base.
My Load Data is also a mite thin with this bullet weight.
I normally plink with 250's and 7.5 grains of Red Dot and build hunting loads with Power Pistol or 3N37 powders.
My alloy is #2 .
Any experience anyone has with this particular bullet and load data would be most welcome.

As well I would like to know in your opinion which Lyman manual has the better cast data for older cartridges; the 43rd or the 45th edition?

Respectfully
Doc.

You may want to try "Lyman's Bullet Casting Manual". You may find what your looking for.

What kinda gun are you using this '250's and 7.5 grains of Red Dot' load in? Do you happen to know your muzzle velocity?

I have used bullets cast from the Lee 230 RNFP mould in 45 LColt with excellent results. Although, these bullets were designed for the 45ACP, I decided to experiment with them in 45 Colt and Unique powder where I attained 1,1/2" Groups. This is now one of my favorite 45LC loads.
The bullets drop out of the mould at around 235gr.
The flat point on these bullets should work great in a tubular fed rifle. I have fired them only in handguns.
My newest Lyman Cast Bullet Handbook is the 3rd edition. I have had it for at least 30 years. I did not know they were up to a 43d edtion.
Hope this helps.
