My custom M98 in 6.5x55 was my deer rifle for 25 years and it never failed. Exceptionally accurate, mild recoil .As Finn Aagaard said , the perfect deer cartridge !!
That said , at this point I have my reservations. The factory loads are wimpy due to old guns.The American companies are loading it but they use a case based on the .473 dia instead of the proper larger case -not good for accuracy.
If you're a handloader then get a 6.5x55SE chamber , reamer and dies, and load it properly .You should get at least 2750 with the 140 Gr bullet and modern rifle. That will get the job done !!
The SE version finally is the compromise between Norwegian and Swedish military dimensions. Yes Norwegian !! They used the Krag while Sweden used the Mauser.I get tired of seeing the round called "Swedish" .6.5x55 and oldy but goody !
