I had a friend ask me the other day what the title says. Not thinking I told him case size and about 3to4 hundred fps difference in velocity. He responded so no real difference. The next mourning thinking about it I thought you know the 7Rem Mag is the regular 7mm. Then I thought about his other statement and thought why does he shoot 3in mag shotgun shells there is no difference fron the two and thre quarter jobs lol. So today I told the guy this and as usual he said I was wrong because he knew a guy with a regular 7mm. Now this guy is a close friend but will not listen to much I say without arguing. I told him that most people when they say they have a 7mm mean the 7Rem Mag. Now am I right or wrong I know there are now a lot of 7mm cartridges out there but is the 7 Rem Mag still the most popular in America? How would you guys have answered this question remember your answer will be wrong or pointless. Not to me but to the guy you are responding to. I am curious to see what you guys would call the regular 7mm. To me this is still a great caliber and the 7 Rem Mag was my first big game rifle.
