Has anyone had any experience with the Sierra 70 gr Blistking out of 257AI.

I have one with a 14 twist barrel (I know, big mistake) and would like to try the 70 grain Sierra.

Looking for starting loads.

Any ideas would be helpful.

Am not too certain of the case capacity of the 257 AI as compared to a standard 25/06, but my Zastava 25/06 likes them, and groups around .75" for 3 shot 100yd groups out of a light sporter factory barrel with 1 in 10 twist. Velocity is 3800 fps with 53g of ADI 2206H out of my 24" barrel.
