Component confusion

[iMigraine]

Hey all,

Looking over my Lyman 49th Reloading Handbook for .40 S&W load data. I found Rainier Bullets that looked perfect for plinking. Since their bullets aren't listed in Lyman Handbook, I checked their website for load data. So now I know to use a middle load for these bullets.

BUT to my REAL question; say I want to use a different primer (CCI SP instead of WSP) than the one listed in my handbook too. So different bullet and different primer. Would it be wise to use the starting load instead of the middle?

Just want to be safe.

Primers will not have a huge difference on changing a "safe" load to an "un-safe" load between CCI SP and WSP.

Load a few rounds at varying charge weights, working low to high, checking your spent rounds for pressure signs. If you're not looking for +p type ammo, all you really need is a charge weight that reliably cycles when you pull the trigger.

There is not a significant difference in primers. If you starting in the middle with the powder charge, you should be fine.

On pistols substituting type for type, you probably won't be able to tell any difference. Rifle is different, sometimes it could.

[JagerDog]

You're always supposed to start at the starting load.

Most literature doesn't even list primer brand, under the context that you start where recommended. At that level, there's not enough difference to be concerned about.

For "plinking loads" it's common to seek the lower accuracy point which still supports reliable function.

Thanks for all the great information. I'm still in the process of learning how to reload. I'm planning to start with my .40 S&W first (it's my only handgun) before trying to reload my rifle.

Reloading seems to be more of an ART with underlying tones of science. With that said, I think that spp = spp and srp = spp and lpp = lpp Etc.

Use whatever primers you got as long as they fit. Jury seems to be still out on whether or not magnum gives faster velocity, but from what Bubbapug posted, it seems that it might be faster velocities with magnum primers...
