Default Proper way to test various pellets

What would be the best way to test various pellets in a barrel?

I assume pull through's between batches is overkill but it seems not enough to simply fire 25 pellets from each batch at a target and judge from that.

At the moment I am thinking 25 pellets (10 fired to ground) 10 to check zero and 5 "marked" with a couple of cleaning pellets fired between batches/types will be sufficient.

I will be filling the rifle to 190 bar before each group and using a 45 yard target to test.

Does this seem reasonable or is there a better way?

FYI the reason for this is that a batch change of JSB exacts have seen my 50 yard bench rested groups go from a ragged hole to a 40mm spread!
