If you are hunting in a place where your shots are going to be long shots, I'd go 4x12 50mm. If you are shooting in wooded areas where a long shot is under 50 yards, I'd go 3x9.

Is weight a factor? The 50mm objective adds a considerable amount of weight, but doesn't utilize the exit pupil increase under typical hunting magnifications.

What's your anticipated shooting distance? If it's inside your MPBR I'd stick with the 3-9x40. If you like shooting at higher power then you *might* see a benefit from the bigger scope.

For 75 - 300 yds a 3-9X40 will be perfect for deer and elk. It's not to heavy and bulky, and will mount closer to the action so your cheek will rest against the stock.

I agree with the previous rec. With young eyes one can only dilate the pupil ~7mm. At 5-6 power you still retain all useful exit pupil from the scope. At 300 yards 5-6 power should feel like 50 yards unscoped. I imagine you would find the added weight from a 50mm objective to be more of a hinderence than a help. If you were really looking for a light weight set up a 2-7x33 would have max usable pupil size with a magnification of almost 5 power. OTOH The 50mm gives a 7mm exit at 7 power. Small and unneeded increase of power for a large increase of weight.

My parents moved to Ruidoso about 10 years ago. Before that I spent my childhood traipsing around the state. Sure is pretty out there.

yeha iw ent to sprtssman warehouse last night to look at soem scopes i liked the bushnell 3200 series the 4x12x40 was 399.99 but it had ballistic sights is ballistic sights that much on an advantage over regular sights there was 100 difference in the same power scope

No, IMO. If you are not shooting beyond 300 yards and you are shooting a high power centerfire rifle putting out around 2700 fps or more then you will have a MPBR of around 275 or so yards with an up/down of 3". Have a +2" at 100 yards and you will never adjust for elevation if your max shot is under 300 yards. Beyond that you will probably need a rangefinder anyhow. I am simplifying the numbers a little, but in practice you'll never know the difference. Once you pick a rifle, ballistic software can polish the numbers to the yard and hundredth of an inch.

A 3X9X40 is all the scope you need. You don't need more magnification, weight or bulk.........Essex
