I've recently been using a method recommended to my by SeanMP who laps barrels regularly.... I use the VFG cleaning pellets in the appropriate size, two of them screwed onto their brass adapter.... I got the one with 8-32 threads to fit my cleaning rod.... You put some oil on the pellets and add some JBs Bore Paste (coarse) and working from the breech polish the bore 100 strokes full length, but trying not to push the pellets all the way through the muzzle.... I add more Bore Paste about every 25 strokes.... Then I do 4 strokes an inch short of the muzzle, 4 more 2" short, 4 more 3" short of the muzzle, etc. so that the breech end gets a total of 200 strokes but the muzzle end only 100.... I then clean the bore with solvent and patches until all the bore paste has been removed and then repeat the entire process using new cleaning pellets and JB Bore Bright (fine).... followed by a thorough cleaning and one patch lightly oiled.... By the time I'm done, the bore is like a mirror, and the chamber and leade are completely smoothed up.... Once you have put at least 100 rounds through the barrel, polish using the same method, but 10-25 strokes, full length, with the fine Bore Bright only.... You are trying to remove excess lead, but leave the lead in the micro scratches in the bore.... You repeat this process until the groups no longer tighten up.... After that, the barrel seldom needs cleaning.... I've only just begun to use this method, but it certainly seems to make a difference.... Sean seems to get miraculous results, it's pretty neat when you see a barrel from a QB pass the "Feinwerkbau Test" where you can put a pellet in the hole in a paper target made by a 5-shot group at 10M and it doesn't fall out.... This is from my .224 cal Hayabusa....That's a 41.5 gr. RN bullet sitting in the hole from a 5 shot group at 7 yards (all the distance I have indoors).... The gun shoots those at ~1030 fps, the same power as a .22LR target load.... The .22 Hornet barrel was prepared as above.... Bob
Resurrecting old thread...When you say "100 passes", does a pass count as down the barrel and back, or is down one pass and back is the second pass?Yes, I'm OCD.
Where do you get Krytek? Would it be under any other names?

Does that take care of the sharp edges at the beginning of the rifling and in the transfer port?
