Pressure signs 6ppc

[cwebster]

I shoot a stock sako 66ppc and understand the action is not as strong as the custom ones. My question is wont a stock action show signs of pressure, like cratered,. flattened primers the same as a stronger custom action? Do custom ppc shooters watch for cratered primers or not.

You may see hard bolt lift a bit sooner but otherwise, yes, the pressure signs are typically the same, so much is left up the the one loading for it to use good judgement in knowing when to back off or stop tipping the powder jug. Those little Sakos are nice in one piece. Primary extraction and bbl expansion both under the smallish tenon and the shank are why you may see bolt lift issues a bit sooner, imo.

The reason i'm asking is Iv'e shot LT-32 28.0gr, max according to the book, with normal looking primers. Seems most are getting good results from 28.2-28.5 just wanted to try a little hotter and see if it groups.I'll will stop at 28.5 whether its grouping good or not.

What bullet weight are you shooting?

Just my experience with the Sako and Ruger 6ppc's, but if you're shooting a 68gr or heavier bullets using LT32...... I'd go no higher than 28.2 (maybe). And be extra careful when you change lots of powder some lot#'s are distinctly hotter than others. Those are nice rifles and can be extremely accurate, no point in getting injured or ruining a great little rifle for 10-15 fps of MV. JMHO.

Lastly, I've found improvements in accuracy on the Sako and Ruger 6ppc's by simply adjusting action screw tension and gun handling. WD

64 berger column

I think you will be fine going up to 28.5 with the 64 grain bullet.
