From what I've seen you can't get a jacketed bullet that's larger than .0005" the boore down the barrel unless you're stronger than I am.Pocampo said:Generally a bullet that matches the groove dia of the bore or slightly larger by appx .001 will shoot the best. Loading from the muzzle end you probably wont get anything down the barrel much over .002" past land dia.
Loading from the muzzle end sabotless I would stick to the bullets with the longest bearing surface that most closely fits the land dia of the bore.

SW said:I tend to think a flat based bullet would be better for smokeless, sabotless shooting for two reasons: 1) it seems to me that obturation of the bullet into the lands would be quicker, more consistently and easier with the flat base, and 2) the most accurate short and medium range bullets are all flat based as far as I know. example: all 6PPC (243) and 22PPC benchrest bullets are flat based, the 52 and 53g 224 match bullets are flat based - there must be some good reason for this. Additionally the 30 cal , for score, benchrest bullets are also flatbased. I realize the longer range bullets are boat-tailed where it must be that the increased BC of the BT helps more than any minor acccuracy degradation due to the BT vs FB. I have a Fred Moreo 22-250AK IMP done as a heavy varmint rifle which is capable of consistent 0.28" 5 shot gps @ 100ydswith 80g Starke bullets but just over 0.3" with 80 Sierras and 75 A-Maxs. This accuracy advantage holds to over 300yds. At 500yds and greater the accuracy is about the same and the BC of the two latter 2 bullets becomes an advantage. At 300yds with a smokeless MLer I see no significant ballistic advantage of a BT bullet.
