Tad,
I would advise getting some Â“junk binÂ” 7mm bullets of any weight, make, construction, or color and use them to fire form your cases. AinÂ’t any sense in using bullets that you are going to work up accurate loads withÂ—they are expensive and why waste them? I strictly use cast bullets in my Waters anymore, so I donÂ’t have a problem with finding cheap bulletsÂ—I make Â‘em! Regardless, if you find some inexpensive slugs, just use a starting load of whatever powders are listed in a reloading manual for that bullet weight. I have had good success and accuracy with H-335 and WC-844 powders. Years ago when I was really fire forming many Water's cases, some of the fire forming loads were quite accurate. Once you get your cases fire formed, and then go to the expensive bullets for accuracy and hunting loads. Good-luckÂ…BCB

I made up a bunch some time back. I know I used 175 rem core lokt bullets seated out to touch the rifling.
I cant remember the powder...pistol I think it was and just a touch them filled up with oatmeal before seating the bullet.
Check some manuels of fireforming loads.

I used some 140 gr seated out to touch the rifling with a starting load of Varget. Actually, they grouped pretty good.

I do a lot of fire forming in 6.5-284 using a full power load under a slightly lighter bullet. We use the loads to shoot ground hogs, crows, target, ect. I have actually notice EXCELLENT accuracy this way. Once fire formed to our chamber we neck size only pushing the case shoulder back only a tiny amount, to insure proper chambering, and use that brass to hunt deer and hogs.

I have a friend that fire forms 7-30's with my rejected 7mm cast bullets. Yep, even the wrinkled ones.
