I have searched through here and have not seen much on the 153 grain A-Tip for 6.5 for Creedmoor.
I will say this... they are LONG.
I started working up loads Tuesday and running speeds on Wednesday. First of all, the bullet really drops at slower speeds... much more than the 140's or 147's. However, the wind has minimal effect on it. At a 500 yard distance, while my 140 ELD-M's were being pushed about 4" or more by the wind, the 153's were only being pushed an inch or so.
I did pick up some H4350 to try next trip.
Here is what I have from the Hornady load Data. Shooting from a Savage 10 Ashbury Ordinance with a 24" barrel.
I had the Superformance and RL17 on hand and saw they allowed the 2650 fps speeds, so I tried, what should have been the 2650 and 2600 loads. All seating was done to O.A.L 2.80.
All brass was shot once prior. Cleaned, sized, primer pocket cleaned, flash hole cleaned from inside. Primer was Federal Large Rifle Match 210M. No neck turning or concentricity yet... That's to come later.
This is all for the 153 A-Tip...
The RL17 at 42.9 produced the best. I'm curious to see how the H4350 does. Also, I want to boost the speed a little more. Clearly, Hornady had a different variable in their testing.
