I agree about the more X for 300, but think I can at least ring some steel @ 200 with the 6X. Using 4X is even tough for me at 100 yards if i'm trying for pinpoint accuracy, but to ring a steel plate @ 100 yards with 4X should be no problem. Even 200 at 4X might work (with practice). I believe the 6X @ 200 yards shouldn't be too tough but @ 300 I'd probably struggle to consistently hit a 8" steel. I think practice would be in order.
My son is hot on buying the 6X model in question and I thought I'd order a second when he makes his order.
For the most part I'll be keeping my fun shooting shorter than either the 200 or 300 yards ranges. Was just wondering about any input about the 2 scopes in question.
