[QUOTE="tim_w, post: 1046784, member: 11132"] As good as any of the premium match bullets. ON the 6.8 they were in AR-15 but we had numerous .25 groups and that's the best that setup had done with any bullet. ONe thing I do really like about these CNC micro lath turned bullets is on the SP they have a needle point tip and the weight is dead on. I weighed 200 and never had a variance over .001 grain. These were of course a smaller lighter bullet than a .338 so I can not say it would hold to that or if its a % of the total but still it was better than any bullet. Honestly I expect this for a bullet made from high quality copper that is made on a CNClathe machine. My point is not to be a fan boy as when something is wrong I will call it; anyone that knows me knows this about me. Do not ask if you do not want what I think is the truth. I lost my BC numbers from my testing of the 99 gr SP 6.8 bullets but they did allow us to keep the bullet super sonic thru 1K from a 18" and sometimes even a 16" barrel but in that is was in the transonic range. We also worked with Nosler and Barnes to create bullets of the proper weight range and OAL for the 6.8 in the AB and TTSX. The issue being .270 bullets are usually to heavy or long. The ideal for the 6.8 was 95-105 gr. It was the ideal balance for COAL limitations, BC and velocity. It was actually our work with Gerald@ GS that helped us to establishm and test these parameters. Sort tf the catalyze of it all. [/QUOTE]
