controlled feed - I think you'll find AR2206 has finally dried up in the meantime, but let me know where I may get some if you hear about it. I've only got just under 1kg left and I'll save that for my 308 hunting loads (and special target loads, if I get serious about competition again - I was only half serious at the best of times anyway).

Daryl S - I think also another factor why the bigger bores also shoot accurately is that the bedding has to be more "solid" from the factory on this sort of rifle - has to be for reasons of the stock taking the recoil. The bedding on the CZs these days is not as good as the earlier Brnos and most will advise to have them bedded from new - mainly to prevent (defer?) splitting stocks (at least in 458WM, 458Lott & 416Rigby). I bought my CZ 375H&H brand new and it was actually bedding on the lug under the rear sight! I bedded it myself (Acraglas) but it still won't shoot the lighter projectiles (270gn and smaller) well. The heavier projectiles are longer (and also usually round nose) and I can seat so they are closer to the start of the rifling and I think this is why they shoot better. Anyway, getting off topic now.
