I need advice, I took the varminter out yesterday to break in the barrel. The weapon shot great held tight groups @ 75 yards. Then I made a couple 250-300 and it was 10 inches or so low, it seemed online but low.

What scope, or what do I need to have it shoot out that far. I have a Tasco 6x18x42 30/30, not a mili dot. There are adjustments with the scope from 50 to 300 yard on the front part, does that compensate for bullet drop?
or is that the estimated range?

My main question is, what do I need for optic, ammo or what, so I can shoot and 100 or 300 yards with the crosshairs on zero,
I hate to guess and hope for the best on long shots.

Please help me out, I need your professional insights.

You can't have the same point of impact at 300yds that you have at 100, the bullet drops.

You'll want to shoot at 100, 300, and any other distances you want to use and make a chart of how many clicks of elevation adjustment you need to dial into your scope for a zero at a given range.

IMHO if you are going to be making a lot of shots out to 300yds, zero for 300 and aim low at anything closer. Depending on your load it could be as little as 5"s low.

Test test test, thats what you'll have to do.

Thanks Phil & Troy, I see your point, seem like a pain to adjust for every shot, but such is life.

Man I was feeling like a redheaded step child, either people or so sick of the same type of post (I did a search first) or they dont want to waste time responding to a newbie, comeon guys I need more advice.

How far, and what grain to use for the flattest trajectory, and is there any other reasonable
options. I rather not to adjust windage every shot?

Hi sniped,

It is physics. You cannot escape it. The rules of nature have no penalties, only consequences.

Your bullet will start dropping as soon as it leaves the barrel regardless of it's weight.

If you want a flat shooting load out to 200 or 300 yards I would suggest you stick with 55 gr. bullets loaded to maximum velocity. With a 200 yard zero you should only be a little high at 100 yards.

Did I mention that you cannot escape bullet drop?

If you are jumping around from 100-300 yards you are going to have to adjust no matter what ammo you are using. Its just part of distance shooting. You want something that doesnt drop get a laser Even then I think the atmosphere will bend that.

I'm feeling better now, Thanks for the responses. I can clearly see shooting well is both a science and an art, I need to take allot of notes on range verses elevation.

Have you have any luck with mil dot scopes?
is the range per each dot around 100 yards or so. I have a line on a Tasco mil dot scope thats been unavailable (backorder). I was thinking about buying it, or would you stick with the one I have now.

Also (I wont ask anymore questions after this)
what is the range dial in front of the scope, what is its purpose? the range is from 50 to 300 plus yards.

Thanks again

That would be for parallax adjustment. Parallax is usually set at the factory at 100 or 150 yds. At any other range, the recticle will appear to move around slightly, potentially ruining accuracy. The adjustment on your scope eliminates this.

As others have stated turrets and mil-dots are a must for accurate POIs. Leupold Vari-X IIIs or Mark IV scopes are what we use as they are exacting and consistently return to zero.

Once scope is zeroed for 100 yards a come-up chart for your rifle can be created like this one, then you can refer to it to assure your POIs are on target.

Come-ups for 24" Colt Accurized Rifle (6724)
100- zero
200-1 1/2 min
300-3 3/4 min
350-4 min
400-5 1/2 min
450-7 1/2 min
500-9 1/4 min
550-11 1/2 min
600-12 3/4 min
700-17 3/4 min
800-23 min
900- no target
1000-35 1/2 min (34-36 depending on humidity)

These will vary depending on your rifle barrel length and the load your shooting. (these are for 24" and 77SMK moly max loads)

Mike
