@cmk If you want to try 240 grain Woodleigh PP projectiles in a .30-06 without creating excess pressure, you need to first determine whether or not it has a tight barrel. The following advice is derived from my own experience with the tight barrel in my ZG47 .30-06 rifle. Actual internal dimensions were verified via use of a soft lead slug.
The easiest way to determine barrel tightness in a .30-06 via a shooting test is to buy a packet of standard 150 grain spitzer flat-base loads and a packet of 150 grain spitzer boat-tail loads; and to then fire a chrongraphed test series with each packet. If both loads come within cooey of advertised factory test velocities you should be good to go, provided that the rifle’s chamber is set up for .220 grain round nose projectiles. If the flat nose load is 150-200 fps slower than the advertised test velocity ... I advise you to select a different rifle for your 240 grain reloading experiment.
Best of luck with your reloading, shooting and hunting.
