The Speer .228" bullets, meant for .22 Savage Hi-Power at some 1,000 fps slower, will also come apart before the target in the rimless 5,6x61 reloads with their much higher velocity, (than rimmed). One (piece of jacket?), took out part of my Oehler 35P sky screen. However, with Norma, Degol and (now discontinued) Hornady bullets in .228" there have been no problems. I haven't tried S&B (.228"), bullets yet.
Jeff Munnell found some of the Speer 70 grainers would fail to reach the target after 3,600 fps, but the Hornady's 70-grain, (.228"), had a much harder jacket. They reached 3,700 fps and achieved sub 1/2" groups at 100 yards. He found, incidentally, that .224" bullets were hopeless in his rifle.
Twist in my Frankonia from 1957 is 1 in 9". In Jeff's rifle, (which had been Dave Wolfe's), the twist was 1 in 8.5". The reason why Dave Wolfe did not use prefixes of IMR or H before the powders he used is that, in 1971, there was only one of the powders with that number, not two.
Beauty is a personal thing, of course. My Walther Roell Mauser in 5,6x61 SEvH has some lightly carved oak leaves in the stock. I also had a Walther PPK match .22LR with much more prominent oak leaves, a stags head and such. The vendor, a gun-shop in Germany said, some people love these carvings and some people hate them, so he had not added any more to the price for them. That suited me just fine!
