Fellow reloaders,

I need help!

I recently bought a reloading press to load 40 S&W, I bought the Lyman 49th Reloading Handbook. When looking over the data to obtain the charge for 180 grain flat point, I see Lyman used a 180 grain Hollow Point. My question is, will the charge be the same for the flat point as it is listed for the hollow point?

Any help would be great!!!

That is generally a safe assumption.

Compare the data to the manufacturer of the powder's load data on their website.

As long as they are both the same, I mean both are either jacketed or lead. You can't use jacketed bullet reloading data with plain lead bullets, especially if you plan to load them on the hotter side. Like Laserjock said, whatever powder you plan to use, go to the powder manufacturer's website and they should have the data you need and it's free.

gun powder is a funny thing. You get different FPS on it depending on how compressed of a load it is, and the shape and weight of a bullet.

Most load data is very specific for the bullet brand and style, but if you see a slightly different brand or style, you can use the low end of the reloading data to estimate a good starting point to build up a safe load for your specific projectile.

If you're starting at the low end, which you should, ensure each bullet hits paper, so that you don't get a squib and ruin the rest of your range day.

Know the signs of when you are starting to get into the unsafe range, and stay out of it. Don't exceed the minimum recommended OAL (which can vary by bullet shape), because it can cause unsafe pressure spikes.
