Anyone have any experience shooting long range with a BAR Shorttrac? I had a BAR with a BOSS, it was amzingly accurate once the BOSS was adjusted to the load, however since I am of a smaller stature, and the gun was so freakin heavy after a few miles in the field, I got rid of it. I just picked up a 300 WSM
BAR Shorttrac without a BOSS ( it was a "good deal"), and it shot the lousiest groups ever with all kinds of loads using 180 gr SPBT of many different manufacturers! Then I read a string for loading the BAR 300 WM and it suggested going to a 150 gr bullet at 3200 fps. I loaded using a 150 gr Sierra Game King, because that's what I had, behind 71 gr of IMR4381, as per Hodgdon's Reloading Center - and BINGO 3/8" groups. We don't have a range that's over 100yds - so the question is: "Will the BAR hold this MOA after 100yds?" Does the gas system affect Long Range Accuracy?
