I figuire this is a good place to start with my project.
I have a Ruger M77 Target in 25-06. Not my favourite rifle, kinda boring, hits everything I aim at.
I want to patch it.
I am thinking using the Lee C285-130R as the base mold. I am then thinking of sizing it in steps to .251.
Long and thin. I cannot jump size it like the .312 to .308. I am concerned about deflection during sizing.
I am partial to Lee molds.
Any other ideas out there?
You might want to start with a .258 mould then size to .251. I think a 130 gr sized to .251 would take a 1 in 8 or tighter twist to stabilize the bullet. I have trouble getting 120gr to work in my 1 in 10 twist Douglas unless I really push them.
Now, finding a mold is an issue.
I like sizing ordinary lead molds. I feel the lube lands holds the paper.
I am contacting Lee, it would cost me as much to have Lee make one as it would to get an iron mold plus handles. I am also very comfortable with aluminum molds
Lee says they will take 8 months, maybe someone here can make me an aluminum mold. I sure have seen some good work.
NEI could make you one, but you said you don't want to be spendy: THAT I can understand! Maybe try to find a 6mm/.244 mold for sale used and patch that?

Pat at Lee got in touch with me on sizing their .289-7mm. We have both agreed it is a no-go. Too much sizing, too much risk of deformation.
Now to find a mold that throws .257. That I can size to .251 and then wrap and size to diameter.
Now to find some specs and maybe get one cut by Lee. That would be as expensive as getting a made up one plus handles. I am also used to aluminum molds.
A 6mm can be bumped up to .251, if you can make up a bump die. Dont think it will work otherwise.
Paper patch molds can be made with a drill (of the correct diameter - with a .250 bore I'd guess at .252. If you pre drill with a slightly smaller drill, a 1/4" drill should be just about perfect.). You must reform the nose to the ogive you desire, and resharpen it. For .25 cal. a .22 cal. set of mold blocks should be fine for a platform. Drills leave a bit of a rough finish, which holds the paper just fine.

We need somebody/something to keep the government (cops and bureaucrats too) HONEST (by non government oversight).
Every "freedom" (latitude) given to government is a loophole in the rule of law. Every loophole in the rule of law is another hole in our freedom. When they even obey the law that is. Too often government seems to feel itself above the law.
We forgot to take out the trash in 2012, but 2016 was a charm! YESSS!
Wow, mayhaps I can find someone to make one for me.
I never thought of that.
