A while back I tried the Hornady 225gr BTHP in the 308 Win with good results. I had a feeling they may not stabilize in the factory 1/12 Rem varmint barrel, but they did, and shot pretty well on paper at 105 yards. I took them out to 1185 yards on a 1 moa target with repeatable accuracy.
Hornady gives the bullet a BC of .67, but It seemed to shoot closer to .71 in my test. I've heard the same from others who shoot it in their 300 WinMag out to well past 1K.
Here is the load data I used:
225gr Hornady BTHP, moly’d
Win brass
3.08” OAL (3.088 touches lands)
CCI 200 primer
RL-17
48.0gr – 2500 fps, sub-moa accurate (20.5" 1/12 twist Rem varmint barrel).
My correction at 4500' elevation, distance of 1185 yards was 41 moa. QuickTARGET predicts remaining velocity 1494 fps, energy 1115 ft-lbs.
The rifle used, Rem 700 varmint, HTG, MK4 3.5-10x40,
The components,
How the 225 looks in comparison to a few others,
105 yard target, I believe I pulled one.
