BB and Omark- the GRRW .58 hawken I had weighed enough with it's 34" x 1 1/8" barrel that sub-120gr. 2F loads didn't kick much at all. I found I could barely stay on a pie-plate (maybe 8" round) at 100 yards off the bench with less than 100gr., but as I increased the charge accuracy got better and better. Where to stop is the tickler. When I reached 140gr. 2F, it was shotoing into 1 1/2" consistantly - no wind. This was back in the late 70's using the GOEX or GOX - whatever the "G" powder was then. Using C&H or Meteor powder in 3F, that charge had to be 160gr. to match POI and group size with the GOX/GOEX powder in 2F granulation. I was using the ball/patch combo that worked so well in everything else I'd shot until that time - ball .005" under bore size, patch of .022" (12oz denim) and bear grease or mink oil for lube.
When powder charges were reduced below 140gr., accuracy fell off to where I didn't trust it and therefore this rifle wasn't any good for rondy's etc. One has a difficult time shooting that much powder for an entire day - the narrow butt kicked me enough that I sold it to a more recoil-insensitve fellow. Great hunting rifle, flat shooting, hard hitting, but not suitable for plinking. At that time, I was a one load for all type of guy. I didn't believe in diferent loads for 'each' range - something even then, guys were doing.
When we built the .69, I found it's GRRW barrel needed very heavy powder charges to shoot it's best, but I put up with mediocre accuracy to save on powder, and used a piddling charge of 80gr. It shot this considerably better at 100 yards than did the .58 with the same powder charge and so was barely OK for plinking with it. Even with it's enormous (in comparrison) ball weight, and even heavier charge, the English-styled .69 kicked with less felt recoil than the much heavier .58 did with it's 140gr. charge. The .69 weighed 9 1/2 pounds while the .58 had to be 11 pounds or better with it's 4" longer, much heavier barrel(smaller hole, same barrel size).
