    I shot it couple years ago and if i remember correctly it was about 9 in low at 400 yards. Was about 4in low at 300. I was looking at a chart last night and it was saying 2 ft. My old 30-06 would only drop 16in at 400. Dont seem right.

    put it about 1.5 inches high at 100 and it will be -16 inches low at 400.just turn your scope up 5 clicks and u should be good to go,i know its 1/4 minute click a turn so that would be 6,but i would turn it up 5 clicks.some scopes are a fuzz more than that or a fuzz less.hope this helps.and know its not 2ft.

    you better go shoot at that distance after zeroing at 100. it had to be more than 9" low and I bet the 06 is lower than 16 if they're both at 100 yd zero.

    The 7mm RM is a very flat shooting rifle...as such it is designed and loaded to generally reach "out there"... I know that a lot of WMA ranges are limited to 100 yds but if possible sight in for 200 or 250 yards...as a fall back, sight in to hit 2" high at 100 yds...

    A good ballistics program, offered free online by many ammo manufacturers, can give you some pretty good ideas...that should be confirmed by live fire whenever possible...

    Even then, 400 yds is a long shot and a rangefinder is a must...being off range a small amount at that distance can dramatically effect the outcome of your shot...

    150 grain Winchester ballistic tip will drop 25 inches at 400 when zero is 100 yards.

    According to the ballistics calculator from Winchester, you would be better off with a 200 yard zero, or 1.5 high at 100, if your scope is mounted 1.5 inches above the bore of the rifle. I like the 7mag. I've shot a few deer with mine, and had favorable results. My current pet load, is 175 grain corlokts from Remington. Before you laugh, my lovely bride was at a yard sale, and called me and asked if I had a 7 gun. After a few more questions and answers, we figured out that she was asking about my 7mag. She bought 80 factory rounds for $5.00. Those dudes will suit my needs well for doe reduction loads.

    Get one of those up in the shoulders and you'll reduce her by approximately half.

    The farthest any deer has traveled after absorbing a 150 gr Winchester from my 7 Mag was just yesterday,
    20 yard shot with a 10 yard recovery, all but this one deer dropped on the spot, he had a very thick chest.

    I'd like to see the results of people shooting 400 yards. I know it can be done, but I don't think it's as easy as a lot of people think it is.

    A range finder turns a lot of 400 yard shots into 200 yard shots.:eagerness:

    This is a exit hole using core locts at about 30ft straight down.

    The 7mm RM has a reputation for producing massive exit holes... I love my 7mm...which is also the most accurate out of the box rifle (Savage M110) I have ever shot...sub-MOA with Winchester 150 gn BST and Federal 160 gn Nosler Partitions... Mine is sighted in at 200 yds with the mil-dots marked on an index card for holdovers out to 500 yds...

    The longest shot I have tried with it (big old mountain 6 pt) was at 275 yds...the buck moved after a doe as I squeezed off the shot and I hit him way back...the 7mm bullet dropped him though after very efficiently emptying his guts all over the hillside...

    Only two deer I have hit with it have moved after the shot, and neither more than 20 yds...

    The Nosler Partition loads make huge exits...
