	Getting ready to campaign my new MVA action .40-65. I have new Star brass and I want to fire form about 20 case so I can make custom dies for trimming and loading. What kind of load would you suggest to form the case. My custom reamer makes a tight chamber overall for PP bullets and I’ll anneal the cases first. Would like something that uses no lead or projectile if possible, if not no problem. Thanks Richard

	I use 9 grains of a shotgun powder 800X (or a fast pistol powder like Bullseye) in a case filled with Cream of Wheat (some use corn meal but it stinks) and a topper of 1/16 inch or so of bullet lube to keep the contents in place. Note - anything in the case besides the powder is a projectile of sorts and is what provides the pressure to form the case. Only shoot outside.

	FYI, I did exactly as oneatatime suggested and it formed the brass perfectly.

	I wouldn't waste the primers and powder. Load it and shoot it.

	I go along with Westerner's reply. Might as well get some good practice in while you form the brass. You might have to expand the brass if your paper patched bullet won't seat or possible have to use some thinner paper but they will still shoot pretty darned good! Tom

I've had some loads that were further away than your slight change that I wanted to fire form, and during the process I discovered the loads were very accurate, even while forming cases. And those donor cases were much different than your Starline brass is to formed brass! I'd start working up suitable loads and go forward, skipping any forming steps.

	Last fall I had some new brass to fireform. I went to a match just to get the cases ready. Did not even weigh the powder just volume measured it like a muzzle loader, no over powder wads. It really sped up the loading process. I shot as well as with formed cases and detailed loading procedures. Just load and go shoot it. Don't waste primers forming cases. Have some fun doing it.

	I'm afraid the days when you could start with new brass every time are long gone!

	OK, I have to ask - what is the parent case you are using to expand to make the 40-65? The 40-65 cases I made for my #1 rolling block are all from 45-70 cases, sized down in three passes using a 40-65 FL sizer. No fireforming required. Just curious.

	He musta ordered 40-65 brass from Starline. Already formed/sized down. Yes just load it and shoot it with bullets. Let the campaigning begin! I used my old Winchester 40-65 last weekend to shoot silhouettes. It was a hoot. Really nice not to have to use a sissy pad. I did have a problem though. After knocking down eight turkeys I got skunked on rams. An embarrassing situation. My barrel is 32 inches long and I think my lube stopped getting out to the last eight inches of the bore. Perty sure that's the first time I ever got skunked on rams. I'll clean between relays next match. So do we get to see your new MVA 40-65?

	What bullet were you using, Joe?

	I was using the Ron Long tapered spitzer that came with the rifle. The lube grooves are perty small. Rather than buy a new mold with big lube grooves I'll just clean between relays. I got used to shooting all day with my 45-90 with no cleaning.

	At one point I was using a spitzer for BPCR. It was very accurate at 200 and 300 but at longer ranges, especially the rams, it got very squirrely when the wind came up. Switched to one of Dan Theodore's mini grooves and all was well after that.
