I wen't to North Ayrshire a couple of months ago to do a side by side comparison with the Mirage range. I bought a box of each of, Supertarget 7.5, Grand Italia 7.5, Pro Extra 7.5 and Bol D'Or 7.5, got Tom to fix one of his DTL traps to straight away, then shot 10 of each shell in a row from peg 3, 1/2 choke. Break wise, not much difference between them, recoil wise, slightly different feeling between the four. Then I shot 5 of each, letting the clay go out far as I could still hit it, like a second barrel shot, then I felt there was a noticable difference in breaks between the Suppertargets and the other three......it may just have been in my head, the other three may just pattern tighter, I dont know!!! After that I went up the sporting layout and shot the long, hanging crow out in the field, three of each on the hang and two of each on the drop (Tom, how far out is the crow next to the battue?) all killed it, but when middled, the Grand Italia/Pro/Bol D'or just seemed to powder it more than break it. Then down to the compak where ther is a long edge on l-r high off the rocks, when I hit it the Supertargets broke/chipped it, but for whatever reason, the other three broke it with more athority, I also shot this clay with half a box of Pro Extra Evolution (the ones with the harder heavier treated shot) now you can tell me I'm talking pish if you want, but when I hit this long edge on clay with these......it SMASHES them, might be in my head, but my head likes them!!!Supertargets are £158/k, Grand Italia are £209/k, Pro Extra £222/k £55.5/250 (I only buy 250 of them at a time, should last me most of the season)I shoot about 3:1 Supertarget:Grand Italia round a normal sporting shoot, after my version of cartridge testing I have given myself compleate confidence in the shells I shoot
In summery, thats how I settled on MY cartridge choise of Supertarget 8's for everything out to 40yds, Grand Italia 7.5's for everything beyond 40yds and I keep a box of Pro Extra Evolution in my bag for anything I need some extra confidence with. Now before anyone says it, I know the Supertarget's will break anything I hit with them, but I use the two different shells/shot sizes as part of my pre shot rutine (I say two as I don't shoot many pro extra's)
