.303 light load

I wouldn't jump down to a low load. Work down to it from a known load. Stop if it does anything weird happens. Getting a bullet stuck in the barrel is a pain (particularly if the bolt is locked in place by the retained pressure in the case).

Small charges of N140 would be difficult as it is too slow. The coatings on the outside of the powder will make ignition and so pressures unreliable.

Fair comment Thanks for the input.
