mixing rifle powder?
Im looking for some input on mixing rifle powder.Would it be alright to mix reloader22 when both have the same lot numbers?Would this have any effect on accuracy or any other variables?Will be loading for my 7mm ultramag. thanks!

RE: mixing rifle powder?
I would say DON'T do this. It MAY be ok, in the end, with the SAME lot numbers, but conventional wisdom indicates that there could be differences in burn rate (and pressure produced) between containers of the same powder. If loading a MILD load, well below maximum, it might not be too much of a risk. However, with handloading, better safe than sorry, in my view.

It is perfectly acceptable to mix two containers of powder with the same lot #.

RE: mixing rifle powder?
It has been my understanding and experience that one can mix lots of the same canister grade powder provided that the lots have the same lot number. I'm assuming you are half way through a batch of brass and ran out of powder? I personally wouldnot have anyhesitation about opening another can of powder with the same lot number and continuing on. Might want to load a couple with the new lot first - and compare them with a couple of the first lot - maybe over the chronograph.
I don't think I would open three one pound cans of the same lot number and mix them together, though. Keep them sealed as long as possible. |

I have and did. No change for me.
You know guys this annoys me. I will build a load for gun and it shoots great for months, same velocity. Then you buy another can and all the sudden, velocity drops by 50fps consistently. Maybe the rifle. But I have seen this several times. Espeically with RL25. |

RE: mixing rifle powder?
Yea, I agree. Its a big investment but worth it for keystone powders to buy in 8lb containers.
Like IMR4350, or RL22 or H1000. |

Same lot is same lot. You can mix them at will with no problems.
