308Win Long Range Loads - CFE223?

[1stmarine]

This is what I did. Got 50 brass ready trimed to 2.005 ALL of them (that took some time) primed ready to go. Got all set up in the back of my truck went to the range. First I found out the biggest chagre I could find at that time 44.5 I have found bigger since then. Loaded 2 rounds at a time. Was just watch for any PSI. sings. By the time I got to 44.3 the primers were getting perty flat case was fine and the report was a nice sharp crack rember no crono. O had a jump of 0.026 (couldnt get 0.025 this was all done at 100Y) Then I back it off to 44.1 loaded 3 rounds shoot them. Thay ALL were within a dime size hole. I gess I did some thing right. FYI I have only been reloading for 3 years now dont have a range over 200Y. Maybe some one can answer this how mutch bullet drop should I expect from 100Y to 200Y I got 3"

That's interesting. do you know the length of the freebore in your chamber?
Also let me know the following and I will tell you what to expect.
Zero at 100?
Bullet 165SMK?
Speed Spread 2700fps?
Altitude
Temperature

Also if you have it:
Wind
Barometer

This is a projected chart with the 168 berger hybrid..
Break speed I have at 1300fps...

One curiosity, do you know of many people making 300 savage brass from .308w brass? I would assume the formed case would be able to take a lot more pressure than the advertised max for the 300 savage.

Any thoughts anyone?

I have no experience with any ball powders for CF rifle reloading. Recently it was suggested I try W 760 or H414 for a modern 6.5 Swede loaded to higher pressures and velocities with 139-142's for a long range load. I am curious, not to be contradictory, why ball powders are as a general rule avoided by long range competitors.

Ball powders, and even some single base powders (Rx15), are double base powders. This type powder is sensitive to changes in temperature. This sensitivity affects velocity and therefore trajectory.
I avoid double base powders except for short range (<200 yds.) target shooting where a 100 - 200 fps change in velocity won't mahe that much difference.

yes. makes sense. I already have some varget good trusty loads so it is time to try some of the new bullets.
Thanks.
