I have been shooting a factory stock 30-378 for the past few yars and have been really sucessful. since the debut of the new 230gr Berger bullets I have been waiting for and finally got that windy day!! Temps is the low 40's with a consistant 10mph crosswind gusting to 20 I have come to realize that most people exadurate the wind, a 10 mph wind is pretty stiff and I can honestly say I have never taken a shot at game under such conditions. We were measuring cross wind with a kestrel 4500 wind meter and my son was calling the gusts and I tried to fire on a consistant 10mph for reference. First up was 600 yds.....dialed my elevation and 3 MOA into the wind and let go a nice three shot group (little low right) of 180gr Barnes TTSX, that has been my go to load for a couple years. Next up I were the 200gr Barnes TTSX, left the 3 MOA wind but have to hold another MIL higher due to various zeros between the loads.....got a nice two shot group with some horizontal stringing....it was gusty. Last came the 230 gr Bergers, kept the same wind and aiming point for the 200gr TTSX and they shot Left!! Almost 2 full MOA better than the 200gr and they defeniately shot inside the 180's......this is about as strait forward a test of BC in the field that I can think of....here is a picutre. You can see the splash signature of the berger bullets as they fragment upon impact versus the Barnes solid copper. Both the 200 TTSX and 230gr Bergers are being pushed by 105.0gr RETUMBO and Federal 215M Primers out of my stock Accumark 30-378. The 200's clock about 3200 and the 230's just over 3150avg. Next lets move to 800 yds.....once again the 180TTSX with 11.75 MOA up and 7MOA into the wind.....fire three rounds....not bad but defeniately stringing.( Still a bit low, I may need to check my zero). I tried to paint the steel between ranges by my spray paint can did not work well in the cold!!....I upped the MOA to a full 15 MOA UP and reduced the wind to 5MOA into the wind. Three shot group of bergers shows very little verticle but quite a bit of horizantal stringing, remember its gusting an honest 10-20 mph...ok Now I am realy liking them this time 2 MOA less dope and shot left of the dot. The wind was from left to right. Finally three 200gr TTSX with the same dope....way right a couple really close but the third one was in the leg of my target STAND!! 800 yds As these results prove, a higher BC rules in the wind!! Needless to say I'm pretty impressed with all three loads.........all shooting done prone with a stock rifle and Leupold Mark 4 6.5-20 TMR scope. Not a bunch of fancy stuff, just pulling the trigger and observing results!!
