Since you named the 8 mm thread, Iím thinking about another topic in this context that might be interesting to discuss. ;-) Adequate calibres for single shot break action - rifles. Iíll try to get it done the easy way now, because Iím going to start with 7 mm and stop with 8 mm which of course includes the 30 cal.
In my opinion, rimmed 7 mm rounds are best suited for SSBA, so Iíll take the classical 7x57R and the more potent 7x65R. The 7x65R is the rimmed version of the famous 7x64 and has about the same performance as the 280 Rem. One great belted mag - round should not be missing in this addition, and thatís the 7 RM.
Now we are coming to an extremely interesting round in the 30 cal. group, the 30R Blaser. This very potent rimmed round of a 30 cal. was invented by Blaser 10 Ė 15 years ago. Especially for use in the numerous numbers of break actions in Europe. It made its way on very short terms and has already gained its fast place in the heart of many hunters. Brass is no issue at all. With new powders and bullets this rimmed round has come extremely close to the performance of a 300 WM. Quite stout recoil in lightweight SSBAs, so a good muzzle brake has to be recommended! This round could give break actions a real boost in the USA and among LRH. Combined knowledge in the US and superb new powders and bullets like the Bergers and ABs etc. should give this round the opportunity of a breakthrough.
Now to my personal all-time favourites, the 8 mms. Since the 8x57 I(R)S has no adequate flat trajectory Iím not taking it on the list. I would recommend the potent 8x75RS, 8x68S and the great American 8 mm RM. All these three need a muzzle brake because of stout recoil. As someone else said before there is something magical to find about the 8 mms due to their final performance on game. + IMHO!
Please come with pros and cons, ideas and suggestions. Every good and passionate discussion is in need of those.
