[QUOTE="Jaredk03, post: 1537651, member: 100527"] Hey everyone. I’m not sure if this is the right spot for this post, so please move if needed. Yesterday I was practicing before an elk hunt I have coming up in January. It was about 10 degrees and I wanted to see how much slower my velocities would be. I was shooting my 7 mag loaded with 68.8 gr H1000 and 162 gr Eld-x. I was shooting thru a Prochrono and it actually showed 30-50 fps FASTER than when I was shooting the same load the week before at 35 deg. I wasn’t expecting much velocity shift and definitely not faster at cold temps from what I have read. At first I was concerned I might be over pressure pushing 3065 FPS, but there were no signs on the brass or bolt lift. I shot at 480 yds with my previous dope and 3017 FPS and hit perfect on a 10” steel 3 times so I don’t think I was actually getting the faster velocities. I was shooting prone and there was snow on the ground and it was very bright. So I’m wondering if this could make the chrono read faster? The low battery indicator came on about half way through but I didn’t notice a change in velocity due to that. What do you guys think? Is my chrono on the fritz? [/QUOTE]
