69gr SMK for 22-250

[Jester8]

Was wondering if anyone would be so kind as to post starting to max loads for 22-250 with 69gr SMK, with H380, Varget, and IMR4350, also COAL. If there is an "accuracy load" powder and charge weight please.

I am a demanding bastard I know, but this would be appreciated.

Most 22-250 tubes are 1:12" or even 1:14" twists, so unless yours is a 1:9", or faster, 69gr SMKs (or whatever,) are probably a bit too long. Sure...you can try and zing them at 4000 fps, but that's nuts.

Stick to 60-62grs and under.

Yep, 69's gonna wobble a bit unless the tube is 1:9

Got one with a 1-7" shilen barrel. The gun loves 68's and up but the only thing I really shoot is 80gr Amax'es at 3200fps loaded wayout (can't rember exact measurement)

As stated before your gonna have to stick to 60 and under, cuz it wont matter how fast you spin them they wont work. I tried it with a 220 swift.
