Good morning fellas. I'm going to load some shells up this morning and hit the range. Decent groups yesterday and today will be some cold bore zeroing.
I have a few questions...
How much POI walking from cold bore to warm bore do you typically expect? I'm zeroing for a cold/fouled barrel so I'm planning on firing at 100yd and then adjusting scope, waiting 10 minutes or so for a cool barrel and then shooting again until I can confirm cold zero. I'm planning on repeating at 200 and 300 to confirm drops. Does this sound like an effective/efficient process or do you sort it out some other way?
Load is shooting just fine with a warm barrel but I did notice a few slightly concerning first shot POI's yesterday when I moved from 100 to 200, and also from 200 to 300 and the barrel had time to cool.
Shooting 140gr TTSX with 60.5gr of H4831SC, 24" 8.7T Rock Creek carbon fiber barrel in .280 AI
Thanks,
Kevin
