how to determine max powder?

[lphhunter]

I am new to reloading. I have purchased several manuals, and decided to use barns new ttsx bullet in my 30-06. in the barns manual it gave several powders. i decided to use the RL 15 powder. but my question is when you change your C.O.L. to fit your gun and this increases your total capacity do you still use the min. and max. in the manuals. or should you recalulate to keep your density between 85% and 95%?

Welcome to it, re-loading is a great passtime AND beneficial to yer shootin accuracy.

 Stay with the listed Min-Max. The charge is related MORE to the pressures developed in the chamber than case capacity.
 The capacity issue is related to the efficiancy of the powder used, how it relates to velocity with variables of barrel length and bullet choice also a factor in determining the "best" load for YOUR gun.

 The primary factor is to maintain safe loads for the gun as it relates to keeping your fingers, hearing, facial stucture and the working condition of the gun intact.

 Better go back to your books and re-read the sections about "Pressure Signs". It's always best to start low and work up to best groups ALWAYS watching for the signs.

 It's really easy to do, just takes time to do it. As you advance in loading you'll become more familur with your gun and what it likes, and where to start. Good Luck,,an keep it safe

The best advice is to never exceed the max. and don't use any loads you see posted here, or on any forum, without checking them against a loading manual.  You will learn from experience that the most accurate loads are less than max. and you will learn about pressure signs.  (Like having to beat the bolt open with a hammer!)  Don't ever shoot anybody elses reloads, except maybe from a commercial reloader.  This is a great hobby and with the price of ammo. today, you really will save money and you can custom load for your particular rifle.  When you find a good load that shoots great in your rifle, cherish it.  Good luck and it's going to be fun.  Dee

I am very cautious of overpressure whenever I am working up a new load.  I always start with a load near the low end, if not at the low of recommended loads from a manual I trust.  ( I trust Lee's reloading manual over all others.)  Then work up in charge weights looking for that "sweet" spot.  I never go over ANY posted loads in any manual.  That way I know I safe sided a bit.

Always take your time when reloading and inspect your work before you go to the next step.   I will save you troubles in the long run.
