The only problem I have found with nicking down is some times the brass on the neck gets to thick and I have had to neck ream. Especially going from 7.62 nato all the way down to 260 Remington. Nato brass tends to be thick anyway.
I just looked again on Midway, they have 50 round boxes of 86 grain Remington Corelocked 25-20 in stock.they are $1.84 per round but it might be worth it if you can't find brass.
I don't have an annealing machine, I just use a soldering torch and spin them in my fingers till they get to hot to hold. Or I put a socket in my drill and spin them that way. Doing it with my fingers I certain not over heat them, lol.
Yes I anneale after every couple of reloads or if necks start splitting. I lost several of the blanks that I might have saved had I annealed but I had a hole bucket full so if one split I just trimmed it and used it for something else. For the most part the 7.62 Nato blanks were pretty soft.
I even trimmed the messed up 5.56 cases all the way down to 9mm and 7.62x25 Tokerov. And the 7.62 Nato down to 458 SOCOM and 45 acp. But that was a lot of work and they were only good for one shot after that.
I have done a lot of repurposing of brass, during the last ammo shortage I couldn't find much on the shelves but managed to find a bucket full of 5.56 and 7.62x51 Nato at a scrap yard. I opened up those 5.56 blanks, trimmed them to make 6x45 and 25-45 Sharpes. I didn't need to make 5.56 ammo...
The 110 FTX must have been for the 25-35 Winchester. Have you tried cast bullets? That must be a pretty slow caliber so lead bullets should work well in it.
25-45 Sharpes does, with a full case of Ram Tac powder and cci 41 primers I get 2688 fps average. When I bought the 110 grain FTXs from midway I assumed they were for the 25- 20. Wasn't it a lever action or am I confusing it with something else?
