Here is my situation. I am a new reloader making up some 30/30 loads for my nephews to be used in their Winchester model 94's. I purchased some 1F 30/30 brass. I suspect the brass might have been more than 1F but I do not know this for sure. My Sierra manual shows a brass cartridge length of 2.039 and a trim length of 2.029. After FL sizing and polishing, I measured a random sample of the brass and got an average of 2.033 which is more than the trim to length but under the cartridge length. Only one piece of brass was over the 2.039 at 2.042. Can I reload this prepared 2.033 brass without trimming back to 2.029? Needless to say, I do not currently own a trimmer. Thanks for any advice.

It is fine. But you will likely need to trim it after another firing or two.
Next time just reference the SAAMI spec and put the case back into tolerance.
SAAMI says 2.0395 minus 20 thou. Soooo anywhere between 2.0195 and 2.0395 should be good to go.

If you are between the two numbers, you shoudl be good to go. 039 is the max the chamber will take, 029 shoudl be the trim length to allow plenty of room for "stretch".
That said, I checked my Cartridge Conversion book - and for 30-30 Winchester, it says a finished (factory spec) case length should be 1.976" long. My CotW book says a final cartridge length of 2.0395

Very few, if any, experienced reloaders will load ammunition for someone elses rifle and give it to them to shoot.
I will reload for close relations, but only if I have their rifle.
Firstly, it's to make sure the sized case will go in the chamber, but most important is the safety issue. I always load the different rifle down a bit, then take it to the range to test. Only when I know it will safely handle full power loads will I load and give them the ammo.
