LRN and LRNFP -- Same Load Data?

[nulfisin]

I'd like to load some 230 gr LRN bullets for my 45 Colt revolver. I haven't seen any published data for that bullet, but there are published loads for the LRNFP. Will the LRNFP load data work just as well for LRN bullets? Thanks.

Yes.

Different lead bullet styles of the same weight can generally use the same load data.
Especially in low pressure calibers like the .38 Spl. .44 Spl, .45 Colt, etc.

Where you might see a difference in starting or max load data is where the difference in the number or width of the driving bands, which could effect bore friction, which could effect pressure at the max load level, especially in magnum loads.

I shoot cast .45 acp bullets in my .45 Colt rounds all the time. While I don't load this caliber for shooting high pressure loads, the bullets have been interchangeable as far as weight is concerned.

Hope this helps.
