I've been looking at the 139gr LRX for my 7mm/08 since at the moment they seem to run about 1/2 the price of the Hammer bullets I'm currently using.
FWIW, I asked Barnes about the minimum velocity for the 139gr 7mm LRX and got this reply:
The important point is that expansion is complicated...
Hammers in efficient cartridges (e.g. 7mm-08) will make you think you're shooting a magnum. 131gr HH's go 3k from my 20" 7mm-08, but FWIW I am dropping that down a bit due to some indications of overpressure that weren't there originally but popped up after a couple years of sitting on the...
The bigger the animal, the bigger the ammo needs to be.

All rifles without a 3-position safety.
I'm glad you showed me! I'm currently in the do-I-go-this-way-or-that-way phase on rebarrel vs new rifle. I haven't even started budgeting yet.
If I had the budget, this would be in my safe already ;).
But to the point of which is better, it's worth noting that thermal properties are ultimately not what we care about. How all these thermal properties affect accuracy is the important thing at the end of the day, but that's way more complicated and will depend on the individual weapon.
Generally speaking, a less dense material will insulate relative to a more dense material, other things being equal. Carbon fiber has ~40x lower thermal conductivity, ~2x higher specific heat capacity (meaning it takes twice as much energy transfer to heat/cool a gram of CF by one degree than a...
7mm-08 for me. I keep looking at other calibers and just can't find any reason to change. It's just really hard to choose more recoil and more expensive components for a marginal-at-best increase in performance.
TBD whether I can work up a handload that will convince me not to hunt with the...
Not necessarily. It's true that the surface of a barrel with higher thermal conductivity will get hot faster than the surface of a barrel with lower conductivity, assuming the same energy input in the bore, but
this is true ONLY if you hold the other thermodynamic variables constant. It's...
Ah, I see. Thanks. I jumped to the conclusion that isotropic effectively meant that carbon fiber means lots of different things depending on formulation but steel is all the same. My mistake (y).
While it's true that the thermal conductivity of CF is variable, it does not mean that carbon fiber barrels can be made to shed heat as fast as steel. (it's also worth noting that "steel" is not isotropic either - alloying formulations affect thermal conductivity).
Insulation or conduction is a...
Quite the opposite. The intensity of mirage is directly related to the temperature difference between the air and the barrel, other things being equal (it's worth noting that the color of the material is usually not equal and has a big effect on thermal radiation, but that's beside the point)...
If I was in the market for a rifle, this would be sold already.
If any are skeptical of the 7mm-08, stop reading gun blogs and buy this rifle. If you hunt at less than 500 yds, the 7mm-08 will do the job on elk and anything smaller without skipping a beat.
Not even a little. The goal is to have enough confidence in where the bullet will land so I can know whether or not to pull the trigger when I've got my reticle on an animal.
If your goal is to put as many bullets as possible through the same hole on paper, awesome. Shooting is fun, and...
All the variables you’ve mentioned are simply the sources of variance, and in no way do they invalidate the statistical methods being discussed here.
In point of fact, they are precisely the reason that we need inferential statistics. If we were somehow able to perfectly control all the...
