Thermal Drift?

[BJDelaporte]

I have my new JP Rifle (LRI-20 chambered in 6.5CM) and the barrel gets really hot. Keep in mind I am not rattling off rounds at a quick pace but it certainly heats up. Has anyone experieced odd flyers due to a hot barrel? For the most part I am consistently getting sub MOA groups at 100 meters but every now there is one out there an inch to a inch and a half away.

Thanks

Heatsinks work both ways

So your saying as it gets hot you will have a slight shift and as it cools back down another shift, or a return for lack of better words. For a gnat's ass zero do you ever zero extremely slowly. Understanding you may be breaking cheek to stock weld?

Thanks in advance again. Also, Im interested in one of the long range courses. Is there a link to the calendar?
