Theoretical question.
You have a 300 RUM sporter and you scope it with a VX3 4.5x14x40 B&C reticle. The scope does not have an AO. This is strictly a big game rifle. Would this really hinder your hunting? Would this be acceptable to you and why? |

You sure that Loopy doesn't have an AO or side focus?

I'd have no trouble with it as a big game/large target set up at all. I use to have a Vari-X III 3.5-10x40AO on my .300 which was my only hunting rifle. The only time I would use the AO would be to tweek the focus when shooting groundhogs or small targets at good distances. Otherwise I left it set at 150yds.

Disregard, I found a couple that don't. I'd say if your going to get that power range, you may be better served getting a unit with an AO or SF.

AO is no biggie for big game way out there. I have calculated the error before, and it is acceptable to me, with the parallax set anywhere from 100 (most common on fixed parallax scopes) to 200 yards.

I was taking for granted that he already had the scope.
I'd get it with AO the adjustment just in case you'd want to use it later for small targets.

On a hunting gun its just one more adjustment to be set incorrectly at the moment of truth. Just remember that balistic reticles are typically used at the highest power with second focal plane scopes (ones where the reticle appears the same size when you change the power setting) That means that as you go down in power the field of view grows wider at lower powers and in a similar manner the distance between those marks on the reticle also change value. You should practice some with it at 6x to see what distance the marks represent at that power because in low light you will want to dial down to 6x or lower to make the scope as bright as possible.

If that is the long range version the parallax is set at 300 yards. The 300 Rum speaks that this will be a big game set up and not having AO will be an advantage. Nothing extra to twiddle with. If you were using it on a varmint rifle the AO would be an advantage because at long range small critters are hard to make out. You may want to have a good set of binoculars to spot with over the scope.

Folks ain't got a sense of humor no more. They don't laugh they just get sore.
Need to follow the rules. Just hard to determine which set of rules to follow Now the rules have changed again. |

I need to call Leupold and ask them about their parallax setting on this scope.
I was under the impression it was set at 150 yards for all of their Big Game scopes without an A.O or SF |

There are several versions of this power range in the VX III line. Is it a 1" or a 30MM tube? If it has the LR designation it was set at 300 yards. I have 2 of the 4.5-14 VXIIIs but both have the side adjustment and the 30mm tubes.

Fotis, you can do the math yourself, and see if it is a worry to you:

You don't need another gadget to have it set wrong on big game hunting rifle, IMHO!

I have a sightron 3-9X40 on my .338 win that has never failed me out to 400 yds. It took a 320 lb Black Bear bore at 525 yards with no wind. I actually prefer a non adjustable obj for general big game for the same fumbling reasons stated by others. If you put in your time at the range and know your weapon system it will not be an issue. With my sightron, I have the eye relief set as far forward as possible so I can see the edges of gray to keep myself lined up perfectly so parallax is not problematic. It may not work that well with a Leupold, but worth a try.

I have came full circle and prefer a good 3x9 scope. The older I get more I like things simple in life. Less things to go wrong. I have 30-06 and 257 wby.

As mention,
Don't really need an AO or side focus and I too perfer 10X or less . If you use anything above 10X then you will need it, but if it gets bumped ( knocked off), not set right and out of focus , it can cost you as shot as it did a friend. The k.i.s.s. rule applies here to me as well. Eagle |

Actually magnifcation doesn't have anything to do with how much maximum parallax error there is (according to the equations used to calculate it), only that it is easier to misalign your eye in the exit pupil, when the exit pupil is smaller.
