You can make the Caldwell work. I built a plywood box for mine and put a fluorescent diffuser on the top. A google search may yield pics. It was much more reliable after that. You will need a strong tripod though.
I have since moved to a magneto speed.
Buy a Caldwell then buy a magneto speed -...
Start with the easy stuff.
Is everything tight/tourqed? Check it all from action screws to scope mounts.
What scope - I missed that?
Change the scope out and try another.
I am guessing this is off a bench? Get down prone and try it out. No rest, just bags front and rear.
Clean the absolute piss...
I'd do a FFP scope with turrets if you are doing 500yds (or more).
Search the used market for Nightforce, SWFA and Bushnell. In fact, I think some of the new Bushnell are under 1K. To clarify I mean the tactical Bushnell, the good stuff.
I think the 270WSM will be fine. Of that 350 rounds, I'd...
The girl driving that boat is almost 18 now. She has gone at life with the same enthusiasm - I fear some hard knocks in her future, but I guess we've all been through that school.
I do not have pictures of the box I built. It was a plywood box, painted black on the inside with a fluorescent light diffuser on the top. The chrono was bolted to the bottom and the whole contraption fit on a tripod. It made my velocity results more consistent - it was an eyesore and...
Disclaimer: I didn't watch the video.
100 yard zero simplifies everything. Build your own tall target 1MOA=1.047 inches. Put a dot at the bottom and a dot at every interval up.
Shoot at the bottom. Dial-up one MOA, aiming at the bottom shoot again. Dial down to zero, shoot again. Dial-up to...
Chrono: I used to have a Caldwell and didn't start getting good results from it until I built a box for it to go in. Also, are you accounting for velocity adjustment of how far your chrono is from the muzzle?
Scope: First, I would zero at 100 - just one of my things - everything is up from...
1. Buy the swaro - if you don't do it now you'll always chase a pair and end up buying twice.
2. Get a spotter with a window mount. Ever plan on coming out west?
