I applied for and received 2 boxes of Bergers 250gr Hybrid OTM Tactical for testing and here are my results. I like them.
This pic should keep you interseted. The final tests were shot at 560 yds. the longest distance I can shoot at my range. This group was shot at that distance with 91.5grs of IMR 7828SSC at 3160 fps. It was sighter group for testing to get on target.
My rifle
Rem 700 with a 30 inch Broughton tube 1:9.3 twist with a Muscle brake chambered and installed by Jim See @ Centershotrifles.
Canjar set trigger
EGW 20 moa base with 4 Burris Signiture Z rings Holding a Burris 8x-32x-50 Black Diamond
Bobby Hart LRT stock Devcon bedded by ME.
Bipod custom made by myself.
I decided to use powders that I already have that I used with the 225 gr Barnes TTSX testing. I don't know if this matters but Broughton says my barrel bore was .3385 so I have been using a little faster burning powders to slug up the bore ( so to speak )
The bullets have a G7 BC of .349 and a G1 BC of .682 I weighed them and out of 100
72 weighed 249.9grs
10 weighed 249.8grs
15 weighed 249.7grs
3 weighed 249.6grs
I didn't go thru the trouble of measuring them, length or ogive, but I did notice the tip ( or hollow point ) on some of them was at an angle, not flat, but that didn't seam to matter in my tests. I have a friend that got a tool to make the tip of bullets flat or uniform on his 6.5mm Berger VLD's and did some tests and at 500 yds it didn't make any difference. ( and that gun would shoot 5/8th's inch groups at 500 yds all day long)
Here is a pic of the bullets I have shot before
