Re: 280 Rem loads
Excellent results with your 280 Rem and the 150 NBT. I am shooting a 280 Rem out of a Remington CDL loaded with 140 Accubonds and 54.5 grains of RL-17 that produces a velocity of 2975+ ft/sec. It is interesting to look at the experiences of different people with differfent loads. I have been hunting deer in Nebraska for a number of years and my results are some what different from yours.
First I have seen 15 or more deer shot with Nosler Accubond and we have yet to recover a single Accubond. Just this year my hunting friends and I shot 7 deer with Accubonds and all were complete pass throughs. The Accubonds were shot out of 3 different calibers(130 grains-270 Win, 130 grain-260 Rem, and 140 grains- 280 Rem..
Second I have seen the Nosler BT blow up on more that one deer. The latest happened to my hunting friend in Nebraska while shooting his 270 Winchester using 130 grain Silver BT's(Same as the Nosler BT). After taking a couple of deer at 200 yards+ with very good results, he shot a doe at 20-40 yards and the bullet blew up on a rib before entering the deer. How do I know this? We did recover the deer after it traveled 300-400 yards. The bones from the rib took one lung out and the deer died. As a result of this I started loading him 130 Accubond and so far the results have been excellent.
My thoughts are this after using and seeing the BT used on deer. If you are shooting at 200 yards are more the BT work great. If you velocity is around 2700 ft/sec again the BT will work great. However, if you have a close shot and your velocity is 2900-3000 ft/sec. you may experience a blow up if you happen to hit a bone. This is based on the result that I have either experienced or have seen during my 30 plus years of deer hunting.
I thing your result are great because you have shot deer at longer range with a heavier bullet and your velocity if 2750 ft/sec.
Congratulations on your success!
