	There are more intresing stuf in this pamplet. I'll see if I can get time to include more pages. Like: "use only coarse Curtis&Harvey No.6 powder" "always use a tight fitting tallowed wad under the bullet" "do not compess the powder" "airgap is not a problem" also they have a "new" bullet for their 8mm express rifle with flat rifling grooves, bullet without lube grooves, without paperpatch

	Swede, Got any more info re 9,3mm express bullet mentioned in old text you posted? All that text gives in "same weight as bird bullet" and for medium game. What was intended velocity, construction, etc. Tis fun to see the older Swedish spellings and words in that text!! Thanks for posting! Look forward to seeing more old Swedish.

	Back out at the range with the chrony trying to get around the high ES. I had a few extra cases so I though I would try a couple of things just to see what the chrony would show. One thing was to try the standard US replacement for the British nitro for black load of using 40% of the weight of black with 4198. Since Swede found the BP load of 50 to 54 grains I shot one load each of 20, 20.5, 21, 21.5, and 22 grains of 4198 giving respective fps of 1230, 1279, 1350, 1177, and 1380. There's that ES again. I also wanted to try some H108 and had enough brass to shoot 2 of each load to get a little idea of the ES. I shot 10, 10.5, 11, 11.5 and 12 grains giving average fps and ES respectively of 950-36, 968-51, 996-43, 1020-100 and 1117-13. Two of those loads had the bullet holes cutting on the target. I think I will definitely work some more with the H108 (as soon as I cast more bullets.) In the meanwhile I have lots of 176 grain bullets (bird weight!) I can try. It was a bad eye day for me and finding that front sight in that little V was a real problem. I have just opened up the V a little and I think next time will be easier.

	When you get a nice "bird load" for your newest M33, you should take it bird hunting: turkeys and blue/dusky grouse would be good Colorado subs for tjäder and orre. However, in order to get a more realistic hunt, you would have to scare them up into a treetop shoot them there, especially tjäder, as is Swedish toppjakt. Especially in winter while hunting on skis.

	Thanks for the load work up data Chauncey! I've got a lot of H108, but haven't tried it in my 33. So I might do some load work up with H108 and see how well it plays in mine too!
