Thread: Updating a 22-250

So today I received a dummy 25GT case from @doubleshot - thanks Darren. I was pondering something somewhere between this (a 257) and it's current 22-250 barrel.

Attachment 246427

This shows some possibilities at the length I have to run them to fit the magazine at 2.5" or a smidgen over 64mm

Cases are 22-250, 25 GT and 6.5x47

Projectiles are 224s in 75 and 88gn, 6mm 103gn, 257's 115 and 120gn (not as long as the 130+ I'd like to run, but all I had on hand) and then some 6.5s just for comparison 130, 140 and 156. I already have a "traditional" 6.5x47 and a modern 6.5x47 so don't really need to go there.

Looking at the 257s I'm sorta thinking all I'd be doing with them is duplicating what I have in the 6.5s . . . . which sorta points to either a 224 or 6mm. I don't currently have a 223 bolt gun but will get another one at some stage.

So what to do, it's gotta be fast twist to move high BC bullets, I like the idea of a walking varminter that bucks wind and has sufficient energy to nail deer to 300+M.

Is there a potential problem getting the throat and jump right/getting the "right" reamer with these long projectiles seated well down into longer cases?

Thoughts?
