Rifleman said:Lets see:
Possible causes of variation of velocity read with same load.
Different Chronos- 50 fps?
Different Rifles- 50-100 fps?
Charge variations and diff. in loading procedure - 50-100 fps?
Atmospheric conditions including temp- 50-100 fps?
Just taking a guess here fellas but it seems to me that there is alot of room for variations in velocity readings from gun to gun, chrono to chrono etc. that could add up in a worse case scenario.
Again, don't know why this is in the advanced forum, this is shooting 101.
ALL very true... I just want to see the number... I'm making no excuses whatsoever...I just want to see 2000-2025fps with 44gr 5744 and a 300gr bullet..
Please remember I am LOOKING at three difference Savage 10ML-IIs. I can tell you I've never seen 100fps variation gun to gun with the same powder charge and a 300gr bullet. Not saying it COULDN'T happen...I just have not seen it. I have five different chronographs here in Athens, AL and neither has read 2000-2025fps with a 300gr bullet and 44gr 5744. I'm not saying it couldn't happen TOMORROW...I'd just like to see it...
...AND I want to ballistically compare the Barnes 300gr .458 Original with a 300gr .452 SST. That will be a GREAT project for us in Crossville! I'm saying..and have ALWAYS said...the 300gr SST will tie or beat it! :wink:
