[QUOTE="RockyMtnMT, post: 1212350, member: 7999"] I just got my 338 lap imp back from Bigngreen and went to the range today to do some barrel break in and start load work with the 307's . My rifle is a 9" twist which puts the 307 a bit marginal for stability at our elevation of 3000ft. My first couple on target were perfect round holes. We started some load work up then and the next on target was oblong. Not good. We may have jumped the gun a bit putting these up on the sight. They are designed for 8" twist but I think they are not stabilizing as well as the stability calculator says they should. These guys are the most aggressive bullet we have designed so far. We are going to move the center of gravity forward a bit to help them stabilize a bit easier. This will probably cause them to gain some weight so we may lengthen the boat tail by changing the angle and try to offset the weight gain by adjusting the boat tail. We also tested a 285g version that is designed for the 9" twist and they shot well. Chose the wrong powder and ran out of barrel before reaching pressure. Will keep you all posted on this guy. Yorke, Go ahead and shoot the ones that you received and let me know how they do. If they do well for you we may keep them as they are. I have a feeling they may cause you some trouble. I will be sending you a box of the new one as soon we get it finalized. Sorry for the trouble. Steve [/QUOTE]
