Hey, i just happen to have and use the exact same gun a remington model 7 youth 1990 in 6mm rem and ill tell you what its a awesome gun. It's a real tackdriver. My gun seems to LOVE remington 105gr extended range shells it groups em .5 inch at 100yds and those shells are great on game preformers. i shot a boar with one about 2 months ago broke straight threw both shoulders and exited the pig. he never even flinched i was amazed with the preformance. The 6mm is a Great cartridge for deer sized game. It's my understanding that the 6mm is the flatest nonbelted magnum caliber also. and trust me it's one little flat shooting rifle. I've never had any trouble with my model 7 6mm and mine also still looks like brand new. Man i still wish they made the 6mm in alot of rifles, i'd go buy me another one. good luck with your rifle as long as you do your part and put the shot where it counts im sure u will bring home the venison this fall. keep me posted and let me know how you like it!
