I just received 3 (100ct) bags of starline brass and I need to fire form them. I'm looking for suggestions on a light load of that new fangled stuff that will allow me to rattle off these casings in short order. 
I have an easy to shoot 340 gr cast bullet for the job. 

My apologies if this question seems a bit retarded. Yes I can read loading tables but nothing beats experience and I have not so much when it comes to smokeless. 

Thanks for any advice

Fill them full of Black Powder and set them off.

    What are you going to load in it?    If BP, just get/make an expander button that will let the bullet slip into the case necks, and load and fire.    Best results with BP are had when the necks are not sized.
     Annealing necks is seldom a good idea.   It is hard to do uniformly, and serves no purpose in BP loads where the necks are not re-sized, anyway.
     If you are going to load s-----less, just load and shoot.  Don't worry about "fire-forming"   which is really only useful if you are radically changing the shape of the ctg.

Thanks Gunlaker

That's what I'm going with then "any old trapdoor load" ish 28 gr of H4198. Then I can get this done with about a pound of powder instead of 4 pds...Lol $30+/pd is the cheap stuff. I cant even get the good stuff here

I think I didn't make myself clear enough.

As Gunlaker points out it takes several loadings of black powder to fully form out a case.

1) I load BP exclusively but I simply don't want to go through all the work to load 300 cases with BP only to get a partially formed case.
2) 300 shots is a lot of wiping
3) There is a 5gr difference between the capacity of a FF case and a new case. Thats going to cause a deviation in the velocity. Remember back to my other post where I said the gun likes a full column of BP.

I'm sure that load will do the trick for you.  It might even be accurate .   Every now and then I shot smokeless out of a couple of my .45-70's and I've found pretty decent accuracy with h-4198 and a 450gr bullet.  Regardless, it'll certainly expand the cases in short order and with no wiping

Chris.

If you really must................ make an expander plug, expand all cases over max dia, then size back so shells just fit chamber. Thereby saving smokeless powder primers lead and labor.

But it's not that critical.

Hahaha Westerner

Not to be a pratt but
.....In a previous thread it was held that an ES of more than 10fps was junk.

I'm reasonably certain that if I have a varience of 5grains in my loads the ES will most certainly exceed 10

Ya I can't argue with that

Alright I'll give it a try. But just for fun I'll shoot 20 and then reload them to see if anything changes.

Speaking of reading I just read the FAQ on the starline site and they do specifically mention the possible need to anneal the case mouths of 45-xx to get them to seal with BP

But does that fall into the reading too much category
