Powders

[grmroper001]

Ok here goes, and b4 i'm told to use the search button, I have. Results were extremely vague, never found what I was looking for. Can someone give me a bit of either insight or direction for information on powders, burn rates and and what you would use a faster or slower powder for? Very new to reloading and would like to educate myself to make the learning curve a bit qiucker ( I.E. less expensive).

I'm sure this is rudimentary for most of you but I figured that I would ask those who know. Pleas excuse my ignorance.

Thanks to all.
Joe

Re: Powders

I'll help ya get started then. What powder for what caliber for what purpose?

Use this search,

Read this,

I would read all the manufacturers sites and info, (example)

http://www.hodgdon.com/

Come back and look at the load section,

Do a lot of shooting and less worrying about the surgical precision so you know what really works for you.

Most importantly - heed the safety of the guys that are 'seasoned'. Don't be in to much of a hurry to work up load speed/pressures so fast.

Re: Powders

Heavier bullets, and more overbored cartridges will generally require slower powders. Big magnum cartridges will produce higher velocities with slower powders. Smaller, less overbored cartridges will produce best velocities with faster powders.

Experimenting with powders other than those used in published loads is a good way to get hurt, fast. Choosing an inappropriate powder is one of the very best ways to end up picking bits of action and bolt out of your face.

Re: Powders

Thanks spot69221, I am going to reload for a 260 I am having built. Mosly for intermediate range (800 yards) matches, might see 1k yards now and again. I am reloading for my 308, 204 and 223 now using recipes out of books and havent deviated from the recommended powders. Want to understand why certain powders are used for certain loads/calibers.

Thanks a ton for the info, reading here I come.

Re: Powders

I like IMR4895 for 260 with 100 gr bullets.
I like IMR4895 for 308 with 150 gr bullets.
I like H335 for 223 with 55 or 60 gr bullets.
I like H335 for 308 with 168 gr bullets.
I like H4350 for 260 with 140 gr bullets, but IMR4895 works fine too.

Re: Powders

Hey you can get some info now. I have not loaded for a 260, thinking about it though.

I got a little grumpy with large temperature swings and my poi, so I decided to utilize the Hodgdon Extreme powders. There is no real problem with temp variants if you keep a shooting log on conditions (one of the first things I write down). I try to spend more time shooting than reloading!

To make things easy I went,

Varget (or Reloader 15) - .223, .308

Seems I can't go wrong, loaded for about 10 different rifles and with little effort they shoot 3/4 MOA or less.

H4350 for cartridges with a bit more capacity - 6.5x47L, .243

I try to load without too much stress on my brass. There are always exceptions to the rule for various rifles/calibers. The combination of bullet weight (per caliber) vs. barrel length for the application you choose will help decide.

Can't go wrong reading this stuff as well,
