158 gain lead LRNFP vs 158 gain lead Sem-wad cutter?

poline · March 15, 2011, 02:47 PM

I've been useing 158 gain lead LRNFP (cal. 38spl), but now I want to use 158 gain lead Sem-wad cutter.

I can find no load data, per say, for the 158 gain Sem-wad cutter only the 158 gain lead LRNFP, actually just 158 gain lead bullet. Therefore, I'm thinking that I can just use the same data for the 158 gain Sem-wad cutter.

It is a rare thing for me, since I joined the forum, to do anything, concerning reloading, without first finding out what the FORUM has to say about a subject.
Any response including......duh..... is appreciated.

THANKS FELLOWS

Yep. Same loading data will apply as long as the weight and hardness stay the same. If the hardness changed dramtically, you might need to adjust the powder a bit to avoid leading in the barrel, but just changing the shape of the nose won't give you an effect.

your OAL might change because where the crimping groove is on the 158gr LSWC might be different from the LRNFP.

Duh....I agree. The nose shape hasnt made a big difference in my loads as long as its the same weight, but you still might have to fine tune just a little.

LSWC data will be very close to lead round nose. There is plenty of data listed specificly for 158GR LSWC, try the websites below and you should find something to suit your needs. I prefer the SWC or even a full WC for target use. They cut an easy to see hole in paper targets and if you are plinking they seem to really knock cans and such around rather than slipping right through them like a round nose.

Other than the possibility that the crimp groove is located a little differently, which could cause adjustment of the OAL (in addition to the bullet nose shape), I would use the same data.

"I would use the same data"
Exactly, unless your load is on the redline for the gun then I would be careful in the load development.
