I have a 6.5 STW built on a Rem 700 action with Nightforce 5.5-22 zero stop on it. Not having any luck finding load data anywhere. Anyway, I worked up a load using 143 gr ELD-X's and 74 grains H1000. They will group about 1/2" at 100 yards and that certainly works for me. I want to shoot longer ranges and getting ready now to stretch it on out to 500 and 700 yards. I don't have access to a chrony and wondering if anyone out there has any idea what my fps might be. Don't want to waste any more bullets than I have to. If I had fps, I could have a better idea of drops to dial in at those ranges.
I ran my 260 out to 1100 yards with 123 gr bullets and known fps and bc, and got surprisingly close last time.
I kmow there's not a lot of 6.5 STW's out there, nut thought MAYBE some one could help me. I want to use the STW this fall for elk in NM. I have a bear with this rifle in Idaho about 5 years ago when i was using the 140 AMaxes and 5010 powder at about 350 yards. But, no more 5010 powder....and I changed scopes so having to start over.
Thanks for any input,
G1 bc of this bullet is .625 and G7 is .315
