What action are you thinking about converting if you’re stuck with a 2.8 inch load length the 6.5x284 is it much better than hot rodding your Creedmoor if you can go 3 inch then definitely go 6.5x284
You can always buy a trigger tech trigger with a bottom safety I don’t currently have one of theirs but I have had several rifles with the set up and it worked well you use your trigger finger to flip the safety forward right before you get ready to pull it
When you said lead sled you told me every thing I need to know also you said you were so amazing of a shot you killed your 200yd deer offhand so why not try a simple field position like pressed on the side of a tree the more you talk the more you sound like a tool.
PS. 0 is the most important...
Straight jacket is doing my prefit and they will do different throats. I got my xm mag today that 10 round mag is huge definitely need to cut it to 3 or 4 .
