Popped into the local gunshop today for some Vhit 133 and they didn't have any. Picked up a partially used tub (approx 20rns used) of 135 for £50 so thought I'd give it a whirl.

Would anyone be able to help me save a few rounds and establish a good optimum charge weight to start with using 53gr V-Max? Max charge weight would also be useful to know

I'm using a standard 223 Tikka T3 Varmint, CCI BR4 primers and new lapua brass. I'll use the same COAL as before which is 2.285"

Any assistance would be much appreciated. I'll hopefully be buying Quickload myself soon. One of my local RFD's introduced me to it briefly and it seemed great with Vhit 133
