[QUOTE="mcdil, post: 2618468, member: 112571"] This will vary depending on the bullet it’s compared against. As an example, the 150gr TTSX is a lot shorter than our 153gr Afterburner. It also has four grooves, which is a lot for such a short bullet when compared to other TTSXs from Barnes. Therefore, it has very little friction in general, and that can be seen in load data for it. It’s a fast 150 compared to others. So, we are 3gr heavier, and when loaded to the same cartridge OAL of 3.370” in our 300 Win Mag, we also crowd the powder a lot more. Even with those two things working against us, on our pressure sensing and radar equipment, we cannot tell the difference in pressure or muzzle velocity between the two with the same charge weight. They are identical. I would think compared to cup and core bullets, the 102gr would be a little faster than 100gr bullets, but the load data should work very well and be close enough to get you in the ballpark safely. As far as production, we are finishing some 30 cal noses from the first batch still. We will cut over straight away to the 264, 277, and 284 in a batch after that. Since these are still first runs, we certainly measure twice, cut once, so it’s somewhat impossible for me to have a perfect guess on timing. I’m really hoping three weeks from now, we have them ready. [/QUOTE]
