An interesting statement in the AL Miller artikel was that he was using 70 grain Spritzer bullets by Barnes of Grand Junction, Colorado. Too he noted that bullets vaporized before they got to the target even @ 15 metres(+/-) the bullets vaporized and even the jacket didn't make it to the paper. Twist rate were 1 in 8 1/2" in the Bolt Gun & 1 in 9" in the Kombo.

Also from »The Rifle« Magazine Number 13 - January - February 1971 - Page 29

„For the single shot, absolute maximums were 54 grains of 4831 and 50 grains of 4350. Estimated velocity is about 3,400 fps for those loads, so they should probably be cut back somewhat for other single-shots.“

I saw somewhere the OAL was 80 mm, but I had to reduce the OAL to 77.5 mm to keep for getting the bullet stuck & powder getting into the action upon extracting the brass as powder gets in every little crevice.

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!

Sorry, I meant a Walther KKM Match in .22LR, (though they did make a PPK pistol in .22LR!).

Very, very favourable report on 44 grains of VV N160 w/ an 80 grain core bonded bullet by Northern Precision. Average velocity was 3125 ft/s(952.5 m/s) and the accuracy was just outstanding taking a fine bead w/ iron sights @ 30 metres. Grouping was around 1 cm and within a 1 cm of where I was actually sighting.... Recoil was a bit heavier than I was expectin' but a joy to shoot. Without glass atop & reaching out to 200-300 metres, I don't know that I would go much higher in the VV N 160 powder charge? But I am going to compare velocities...... Low was in the 3080 ft/s range with high in the 3170 range.

AL Miller in his publication in The Rifle - Jan.-Feb. 1971 gives the original data given for the 5,6X61R vom Hofe Super Express is 46,935 psi & a muzzle velocity of 3,280 fps(ft/s). I may inch up towards 45 grains of VV N 160 but I am only say 100 ft/s on the top side from the guesstimate......

Anyone toss any wisdom to me as to press on a little more for a tad more velocity? Should a try a slower VV N 170 or faster VV N 150 or even my preferred VV N 140? To tell the truth, without glass on it, I am well satisfied.

44.4 grains of VV N 160 just has a ring to it, so I may try that....
