[QUOTE="RockyMtnMT, post: 1767359, member: 7999"] I would run the 117g Hammer Hunter like you stole it. We are getting 3400 fps from the standard 270win with rl16. Guessing the ai will get another 100fps. One of our customers took a large bull elk with the 117g HH at 570y from his 270wsm. He was running them just shy of 3500 fps. I'm not sure your altitude, but I ran 2000' elev in JBM at standard atmosphere with a vel of 3500 fps. This would run to 700y and keep 1745fps. All conditions right I would be comfortable with this. 10" twist in the .277 cal is a tough thing to deal with for long range. There is only one way to make bullets heavier. They gotta get longer and it requires more twist. Bullet weight is the biggest factor when it comes to bc. Our 133g Sledge Hammer will fully stabilize in the 10" twist and it will run very close to the 117g Hammer Hunter. Not nearly as sexy of a design but the weight gets the bc higher. We have not rung out the 133g at longer ranges like we have with the 117g. So not positive it will hang in at the longest ranges. Will be close and with the 2.5mm hollow point vs the 1.5mm hp of the 117g Hammer Hunter, it will open much easier at low vel. We advertise 1800fps on all of our bullets regardless of how low they will go. It is the only place that we let our ethics inflict our marketing decisions. If anyone is comfortable with lower vel impacts they should impact test whatever bullet they are using to make sure it will do what is expected, regardless of what the manufacture says. Pretty easy to say that a bullet performs properly on game at 1500fps. How many people will ever know? Very few can make that shot and chances are it will pass through the animal. I had a customer contact me a couple of days ago to let me know that his area game warden used his rifle to take a whitetail buck at 1890y with our 260g .338 Hammer Hunter. One shot dropped it in it's tracks. They recovered the bullet in the off shoulder. Zero deformation. To my calculations that put his impact vel at 1200fps from a muzzle vel of 3450fps. Right at the sound barrier. Did this bullet perform properly? I guess that is a matter of opinion. Deer was DRT. I wouldn't do it. [/QUOTE]
