Having read other people's reviews on Quickload I decided that I would give it a go. I justified it on the basis of 1/2 tub powder and 100 heads would cost the same and it it could save me that and time I would give it a go.
Load data for my rifle and once fired brass and barrel showed a charge of 39.4 and then 41.3 grains of h4895 with my tipped match kings as acureacy nodes using the optimal barrel time theory. Takes a bit of work to get all measurements exact to enter it into Quickload for reliable results.
Must say I was a bit dubious as but gave it a go, loaded a round at intervals to check for pressure. Here are the results. 3 shot groups at 39.4, 41.3 and above loads 100 yard .308. Not bad for a factory .308 tikka 20" barrel rifle.
