Inquiring minds want to know.
When I started my professional career the first DG rifle I bought was a Remington Model 700 classic in 375 H&H. The straight classic stock looked good. The rifle was too light for the caliber and recoil was not pleasant. The mag only held 3 cartridges.
I experienced some misfires with this rifle indicating some issue with the bolt/firing pin. This could never be resolved. Then it would fire and every now and again it would not. The same round fired through a different rifle would fire no problem.
I could never get the bolt smooth it always seemed sticky.
Reloading it at speed from the top into the mag was also not done easily. If not done exactly right they would pop out again. Slow to reload. Double stacking or double feeding also occurred.
The safety had to be kept clean, any small debris would cause it to not move properly.
Others experienced same issues with 375 H&H and 416 Remington in the M700.
Broken extractor claws where not uncommon.
Cracked stock.
I got rid of this piece of junk after the first season.
I bought a ZKK 602 action(with pop up peep sight), found a original classic stock, fitted a 375 H&H barrel and never looked back. This rifle never gave me any issues even after many years(27) of hard service. I still own this rifle and use it and many clients have done the same.
I know own 3 DG rifle on the same action and have never experienced a single issue with either of them.
Anybody can use what they want but the Rem m700 is a poorly put together and constructed rifle. The bigger the calibers get the bigger the problems become.
I need a rifle that is 110% reliable everytime I use it be it for DG or PG, unfortunately the Rem m700 falls far short.
The argument that police and the military use them as platforms for sniping purposes holds no water and has nothing to do with the effectiveness of the system when compared to DG hunting or even PG hunting.
Yes they probably can be worked into very accurate rifles for long range application be it sniping or pg hunting, however reliable and 110% they are far from when used under short range charge situations in bigger calibers.
How you conclude(that is my understanding of your statement) that if they are good enough for the US forces they are good enough for DG hunting is beyond my experience.
If you plan on hunting DG find a reliable rifle, the m700 is not.
I will be most surprised if there is any experienced DG PH on this forum that uses a Remington M700 in whatever caliber as a back up rifle.
Most if not all will be using either a Mauser/or Mauser type actioned or ZKK 602 or CZ actioned rifle or a good double.
A Remington M700 is what it is but it is not a DG rifle.
