Quote from: sakorickafter reading each and every post in this thread....no... the 6.5 is not the perfect caliber. The 6.5x'06 seems to get in the top 10. Regards, Rick.:D
Quote from: CAfricaNow that really is an interesting graph. If you say it is also similar for the other 6.5's then it seems that the 140gr Nosler Partitions that I shoot in my 6.5-06 happens to be a good choice. C, after creating all these graphs, I think I'd go with Nosler's 125 Partition. Its performance is "close enough" to the 140s that I'd opt for the reduced recoil of the 125. This only because it's a Partition. I'm still experimenting but I seem to be able to launch them at around 3000ft/s + from my 26"bbl. I asume you'r basing this graph on published BC's and published velocities available in each calibre for each bullet? So the "variance"between the 4 100gr bullets is due solely to a difference in BC? Is that correct? Absolutely. Most of the velocities came from P.O. Ackley, or Richard Lee. The BCs came from the manufacturer ofhte bullet. I set all bullets of the same weight to the same muzzle velocity. That is of course not technically correct, but I'm sure the differences are insignificant with respect to this exercise. Regards. Looks like I shoulda made these graphs before I bought all those "light" bullets. :o Actually, I did get some 129s. But truly, I like the idea of the 125 Partiton. C
Quote from: HondoJohn6508Paul, As I understand your graph, a bullet selection of anything from 120 to 140 grains gives the max delivered energy to the game hunted at 300 yards. Am I reading this correctly? Absolutely correct John. Based on my memory(oops!), the 120's like the Nosler BT would more than likely give the flatest trajectory to 300 but not by a whole lot as compared to the 140. Here are the BCs for the respecive bullets. 120 BallisticTip - .458120 Spitzer - .368120 BTHP - .403125 Partition - .449140 Partition - .490140 BTSP - .490140 BTHP - .526140 A-MAx - .550140 SST - .520140 Spitzer - .465 As you can see, the 140s 'hold their own' with BCs. But I would agree with your assessment below, except that I'd probaly choose a BallisticTip 140 for Moose. My experience with Partitions is that they penetrate very well, but they blow back to the partition, and have an expanded diameter of just slightly larger than nominal - only .264" in this case. I wouldn't be worrying about penetration if I could deliver 2000+ ft-lbs of energy with a Ballistic Tip. I'd rather have the bigger hole. So for antelope, whitetail and mule deer or perhaps Bighorn sheep or Mountain goat, the 120 Nosler BT, 120 Sierra Gameking and the 125 Nosler Partition would be the bullets of choice to do the job required. Given an accuracy maximum of 1.5" at 100 and 4.5" at 300 yards. For elk or caribou, perhaps a selection of the 140grain bullets available would be the better choice. I would think that the Nosler 140gr Partition would be the bullet of choice for moose. What say you? Ol' John..
