So I uber got my self into a little bit of a confusion on what is safe to hand load for my L42 clone, it is made from all original parts with a 20 tons proof. I can only find official load data for 308 Win, or people’s kids data for 7.62 NATO. I am aware that both 308 win and modern 7.62 are more powerful than L2A2 ball, and I am rather concerned that 20 Tons per square inch is only 44,800 psi and my published data likely being for SAAMI 308 at 62,000 psi.
So am I just being over sensitive or does any one have any pushed load data or personal that they can share?

Component wise I am happy to consider anything readily available in the uk, but I have on hand: N140, IWI and GGG cases, CCI BR primers, and Sierra 150 SMK or 155 TMK bullets.

Thoughts?
