Gents I will reply properly when I get a chance from work. But this is generally where my thought process is at from a .270 user.
Is there a better rebarrel / twist rate if you were going further down the line?
Basically less wind drift should in theory make things ‘easier’.
I agree some calibers are also getting more sleek , high BC bullets than others.
Hello buddy, and good point about the potential issue of long sleek 270 cal bullets probably not being as plentiful as 6.5s or 7 mms.
However hasnt the US military recently commited to a 270 cal project ? If so that could be significant, as military used calibers have way of ending up being popular.
In terms of 270 caliber catridges and chamberings allowing for long high bc bullets i believe the 6.8 western addresses that issue already. And from what i understand, it is picking up popularity in the states. So let's see, it might just come to europe soon enough, and perhaps replace a lot of the current 270 chamberings of many rifle makers.
I think you missed the point copper is lighter that lead so a 100grn .243 copper would be longer than a lead 100grn .243 so require a different twist.
yep, about 20 percent or so i believe, if we're talking similar bullet designs.
In general as to this topic, i think the poster who stated that there is no free lunch hit the nail on the head. And given that we are all different with regards to what we prefer, (and do not prefer in our rifles), as well as to what sort of deer, and in which type of terrain we might primarily be hunting, deciding which lunch is best for you really is a personal as, well, ordering lunch. ,)
Now unless you're primarily going to be hunting your deer in the hills or in the mountains, where longer shots will more often be taken, going for almost any one of the many mid'sized cartridges already mentioned in here might suit you well.
If you're new to shooting or recoil shy, maybe go for one of the smaller alternatives in terms of case capacity and/or the typical weight of bullet used, as both these elements affects recoil. Then again should you go for a 270, 30-06 7x64 sized case, which to some might seem to kick a bit, just make sure to put a suppressor on.
If you have access to a shooting range near you, and have a chance to go down there with a hunter friend and test shoot different calibers, that could be a good way to find out what you prefer.
As for the do it all cartridge argument, well, i do understand the sentiment, as who wouldnt want one single rifle that exceled at pretty much everything? But again, there is no free lunch, and every cartridge probably has a sweet spot where it does something quite well. So picking the tool that best suits the kind of work you'll primarily need to do with it, but is then ok at the other things you might occassionally need from it, is probably wise.
PS. If you want to to travel and hunt with your rifle, do be aware that some countries have caliber minimiums of 6.5 or 7mm for hunting certain types of game.
