Grain explanation/reasons

Tell us please, in just a few words or maybe lead us to a link that explains the reasons and ramifications of the different grain weights for handguns. For different grains is more powder required? Also for reloading why the different head shaped bullets?

LET IT BE KNOWN, THIS CONVERSATION IS FOR GENERAL ACCEPTED DEFINITIONS. TO BE USED ONLY AS A GUIDELINE FOR BEGINNERS INFORMATION.

Thanks, ammo newbie

Think you opened the can of worms ...

You can get 392fp from a 90gr 9mm, only 326 from a 147gr. You get 399fp out of the 115.

But out to where the 90gr drops off to 206fp the 147 is still carrying 275fp

The 90gr bullets starts out at 1400fps. The 147 only goes 1000fps, you push it any faster and you'll blow the tube...
I'm for the most energy, its the shock that kills... you can poke a hole through a deer and it might just stand there and look at you... you put a crater in one and it will likely be planted.
No... a heaver bullet will.take more pressure to get it moving, you will probably want to go to a slower burning powder to get the most enegry, it will have a lower pressure spike but push longer.

You can still use the faster powder but you have to use less of it to lower the pressure, and energy.
Yeah I'm for the light and fast,
You can only put so much pressure into the tube, for SD you want all that enegry back now!!! For my hunting loads for my rifle and revolvers I want something that carries its enegry a while...
Its a spray on lube for lead bullets, I haven't used it, I'm sure it would be a lot less messy than the waxy oily based stuff I'm using. Alot!!!.

I'd still clean my barrel
