40-65 brass from 45-70

[Boulder Canyon Bob# 32052L]

Trying to form 45-70 brass to 40-65 and having no luck. I'm using mostly Starline brass, RCBS 40-65 sizing die and Lyman T-Max press. I'm not the strongest guy by any means, but they will barely start and that's it. If I turn the die out and do it in 4 steps it gets it done, but the brass REALLY looks crappy. I've used One Shot and Imperial with the same results. What am I doing wrong.

Why not use 40-65 brass?

If it was available I would.

I resized 45-90 into 40-82. It took multiple steps and I kept turning the case 90 degrees as I did. The first few were ruined but practice made perfect. You also will want to anneal the brass first.

You want a Lanolin based case lube like Dillon sells. 

The wax based lubes are useless.

I’ve done it with the Dillon lube.  Worked for me

Powder Valley has it on their website.

If you still can't find any, PM me. I've got a bunch of once fired and new Starline.

Selling my Rolling Block and all the brass and lead.

I'll separate it if you need brass.

This is true. I changed case lube and it made a world of difference.

Thanks, for the responses, I'll try some Dillon lube. I've got lots of 45-70 brass after I sold my Trapdoor and Sharps,

I made a lot of .40-65 brass from .45-70.  It's a slow process.  I used Imperial case lube.  Had to work slowly, about a turn of the die or so each press, but I lost none that I can remember and the resulting brass shot well in my Browning BPCR.  Just don't get into any rush, and size first in a .45-70 die.  It works....

Try Buffalo Arms for the .40-65 brass? https://www.buffaloarms.com/40-65-winchester-starline-case-str4065.html

Says Out of stock, but they do get stuff back in.

Bob I could trade you some 40-65 for 45-70 if you are shooting this weekend at Rio or Tombstone. I can also show you how to convert what you have.

Same thing for me and my Browning BPCR.  I've made several hundred using star-line brass and haven't lost a one.  I anneal the brass first (very important), per star-line instructions.  It takes 3 passes thru my RCBS dies.  The brass grows a bit long, so when I am finished, I trim the cases.  I found it helps to fire form the new case before shooting them in competition.

I started re-sizing 45-70 brass to 60-65 before new 40-65 brass was available. I was having problems as described above until an old timer told me about anhydrous lanolin. I had my druggist order a one-pound jar and it solved the problem. A very light application and re-size in one smooth stroke. You do have to clean the residue from the brass before trimming to the correct length.

Starline 40-65 brass is not the correct length. It says so right on the order page. It comes about .015" short of the the correct OAL. No big deal if you're not shooting in competition.

I ended up sizing 45-70 and then cutting to the correct length.

We also had a friend GW, that dipped his fingers in STP oil treatment and spread on cases for sizing lube......Think about it you'll come up with his name.

I am not so sure that short brass is all that important as I once did.  My son is a AAA BPCR Silhouette competitor (now working on his Masters class).  All he has ever shot is Starline 40-65 brass.  I load his rounds, and some are as much as .020 short.  Go figure.

Some guys go crazy over that stuff. Me I'm more of a exact weight load and every bullet within a grain of each other kind of guy.

We are shooting Rio,I'll bring some 45-70. Thanks

[Boulder Canyon Bob# 32052L]

Thanks for the responses, I did borrow some Dillon lube and while it was better it still was quite a chore and made the resized brass look pretty beat up. Thanks to Flying W for letting me get some 40-65 brass. Now just the LONG wait for the CPA to show up.
