windtalker, to be honest I have no in field experience with the 200 class bullets but in my mind you'll have to either find a higher charge or move up the latter in bullet grains for your range. Reasons, down range energy and wind drift. The 240 xtp is really a 150 yard projectile IMO, its low BC makes it really drop off interms of ballistics. Having said that I have harvested 2 deer with 240 xtp that were over 150 yards both mule deer doeslongest being198 (LRF). If it shot well I would have no problems using it, providedI put the time required at the range to know the factors involved.FYI, my loads were 120 of RS or 95gr 777 FFG out of TC, Knights and remington inlines.
The last few years I have moved to the 250SST under 105gr 777 FFG in my rem 700mls with 209W primers, this load has taken deer from 30 to 210 yards. It lends itself a little better atdistance but I only took that shot with perfect conditions and it felt right.
You can use your current measuring device, just throw 90 or 100 then throw 30 or 20 grains to get to 130 gr loads. In the field you'll have speedloaders I assume.
Also your cold barrel impact is the one you should concentrate on in terms of hunting. Make note of the differences and wheter fouled or clean changes your POI. Set it up so when the firstshot ringsit goes where you want it to andtest it in hunting temperatures/conditions just to cover allthe basis. ML hunting and warm barrels doesn't really go handn' hand
