Reloading 45 acp

[DPorterofWA]

Reloading for a 45 acp, I was wondering if the load data for 230 gr RNFP and 230 gr LRN would be the same.

Does the bullet vendor have any data for you?

Considering that we don't even know what powder you're using...the answer would be no.

Will be if they're both cast or both jacketed bullets. You load for the weight, not the shape, but do not use jacketed data for cast bullets.
Your pistol might need a bit of tuning for FP's though. Isn't a big deal and it depends on its age. New pistols are usually FP(SWC) ready. It's just a matter of extending the feed ramp about half way up the sides of the chamber.

Short version is that it depends. As others have noted, lead versus jacketed makes a difference. So does seating depth (which is not the same thing as, but is influenced by, COL). If one shape has to be seated deeper in order to feed or fit the chamber, then that's going to raise pressures, which will lower the max.

Have you read all of the introductory materials in a couple of reloading manuals? One can load by just following the recipes, but a good understanding of the principles involved helps a lot.

Both lead bullets? If so, yep. OAL may differ slightly, but not a problem if you use the Plunk Test...

K.I.S.S. Begin with starting loads and you'll be fine.

Assuming all else is equal except the COL, it will depend on the space that the bullets occupy in the case. With more of the bullet in the case means the the pressure will be higher.

Exactly the same? no.
If you're not at, or exceeding max, maybe you can make it work.

But I'd start low & work up.

Win 231

Both cast, only load data I find is for LRN, just wondering if I could load RNFP using that data.

Start low and work up. You should be OK.

Sorry, wrong thread lol

Welcome to THR DPorterofWA

Hodgdon shows 4.2gr to 5.3gr for jacketed 1.20 OAL and 4.3 to 5.3 for lead at the same OAl of 1.2"
I like 4.7gr of HP38 (exact same powder as W231) with 230gr lead or plated.
5gr also shoots well for me but I think the 4.7 load is a tad more accurate.
I would load maybe 10 at 4.2 or 4.3, 15 at about 4.5, then anotherr 15 at 4.7 and finish with say 10 at 5gr. You might want to work up to the MAX but for practice/fun I think you will be happy with 4.7 or 5.

I had some chrono #s for both loads but due to a harddrive crash I lost some data. AS I recall the difference between the 2 was about 25-30 fps.
