7mm-08 Remington (Handgun)
Date: Apr 24 2020
The .308 Winchester was introduced in 1952, and as early as 1957 wildcatters began necking it down to 7mm to create the 7mm/308. In 1980 Remington introduced the 7mm-08 Remington commercially in its Models 700 and 788 rifles. The cartridge quickly became popular and most major rifle makers began offering rifles. It has earned an excellent reputation on target ranges and in the field and has also become popular in single-shot pistols such as the Thompson/Center Encore. It delivers a flat trajectory and notably less recoil than other bottleneck “deer” cartridges such as the .30-06 etc.
There are some excellent bullets available for target and field work. The Hornady 120-grain VMax pushed to around 2,600 fps is an excellent choice for varmints. The various 139-grain bullets, such as the Hornady SST, GMX and Interbond offer the best blend of velocity and bullet expansion for deer sized game. Most powders pushed these bullets to around 2,400 fps, with IMR-4064 reaching 2,571 fps (only 229 fps slower than factory loads fired from a 24-inch rifle barrel).
The Hornady 175-grain RN bullet had to be seated rather deeply at 2.720 inches, to prevent contacting the short leade of the Thompson/Center Arms Encore pistol.
Some variance was found in case capacity from five different manufacturers, which will change velocities and pressures. As always, begin at least 5 per cent below maximum listed loads and work up to maximum charges while watching for signs of excess pressure.
