IIRC, Denton found that barrel temp is more critical than powder temp when determining PSI/Velocity.
When posters offer their own findings here, how are you controlling for barrel temp especially while firing multiple shots to obtain sufficient samples to be statistically significant?
I did not do anything special other than let barrel cool between shots (admittedly cool, not cold) and I did not allow the new round to sit long. Basically chambered and fired within one second or so. No aiming.
