SOURCE: Rifle is shooting

The reason your shots are stringing is because the barrel is touching the stock probably at the end of the forearm. As the barrel heats up, the problem gets worse. Try sanding out the barrel channel and free-floating the barrel all the way to the recoil lug. Next, torque the action in the stock the recommended amount with an inch pound torque wrench. I torque my Remington 700 at 45 inch pounds for the front screw and 35 inch pounds for the rear screw. If you have a plastic trigger guard, 35 inch pounds will be too much for the light plastic trigger guard.

SOURCE: How to use the BDC on my rifle scope


  1. Step 1 Take a rifle with a properly installed BDC bullet drop compensating reticle to a rifle range. Using ear protection zero the scope reticle so that the point of impact corresponds to the center of the cross hairs at the distance you have selected - typically 100 or 200 yds.
  2. Step 2 Determine the trajectory of the specific cartridge you have selected. There are several ways to do this. Ammo manufacturers publish trajectory and wind drift information. There are web based ballistic calculators like http://www.biggameinfo.com/BalCalc.aspx which will tell you how much your bullet drops at known distances.
  3. Step 3 Scope manufacturers like Leupold can be a valuable source of information about their reticle: "Leupold® Ballistic Aiming System: Boone and Crockett Club® Big Game Reticle aiming system provides a series of additional aiming points to improve your ability to shoot accurately at longer ranges. Nikon2_bing.gif also provides good information suggesting the marks on their reticle be used for zero at 100yds followed by circles below representing 200, 300, 400 and 500 yds if the cartridge travels around 2800 ft per sec. Nikon suggests the center cross hair be zeroed at 200 yds for magnum calibers traveling around 3000 ft per sec. We understant that each variation of different bullet weight and powder charge changes trajectory and a scope manufacturer can not build a different reticle for each different cartridge made so practice on the range to determine how well the marks relate to the actual impact of where your bullet strikes at a know distance is important. The one thing that people using BDC scopes typically have problems with is that a BDC scope has the reticle in the second focal plane of the scope. If the reticle was in the first focal plane of the scope the reticle would look smaller on low powers like 3x and grow proportionately larger as the power increased to say 9x top power. The problem is that while the marks on the BDC reticle correspond accurately to the bullet drop at the know distances 200, 300yds etc. What happens when you lower the power from the scopes maximum power to any other lower power is the reticle stays the same size and the field of view within the scope increases which means that the distance between these marks on the BDC reticle no longer corresponds to the point where the bullet will strike. In short BDC reticles only work at the maximum power of the scope or at a set specific power. At all other powers these BDC reticles do not accurately represent where the bullet will strike.
  4. Step 4 The center X always remains the same. If you zero at 100 yards and you know that your bullet drops 8 inches at 300 yards you could forget about the BDC marks and hold the center X 8 inches high - that works at any power 3x or 9x and should be used at lower powers. If you zero the center crosshair at 100yds and have the BDC scope at the maximum power 9X then the first line or circle below the center X should be the mark you place on the center of the 200 yard target----- the bullet strike should hit the center. If by some chance you put the scope on 3x and placed that first mark below the center cross hair on that 200 yard target you would shoot over the top of the target. This is because as the power of the scope decreases the field of view increases the angle increase and gets wider. You can experiment with known power settings and see at a specific power say 3x what that first circle down corresponds to and make notes because at any set power what the marks correspond to will be repeatable.
I got this from a website, hope it helps.

SOURCE: I got in a tight spot needing a scope last season.

well one day you may lurn that cheap is cheap! and tasco is rubbish cheap! i would say without dought the cross hair in the scope has shaken apart,,,due to recoil,,,a 30-06 has a big recoil
try holding the rifle stock on your jaw and firing the rifle off?
when or if,, you wake up in hospital with a shaterd jaw and with no teeth left in it you will know then! and cheap tasco scope is an air rifle scope it cant take 2500ft/lbs of recoil???
so it wont take much of a kick to mess it up,,
i put one on a 303 enfield??? i got 3 shots before it fell to bits!
if your going to buy cheap scope's go for nicon gold crown?

What would you recommend for the most accurate load for a 6.5x55 swed 96 mauser using a 140 grain bullet

48 grains. That round is hard to reload. You are probably out of spec for chamber clearance.

How much bullet drop with a 130 gr bullet out of a 270 at 1500 yds

Are you sure of your distance - that is 4500 feet, or .85 miles. Here is the drop up to 500 feet:
270 Win Ballistics Chart Coefficient GunData org

Firing 130 grain bullets at between 3250fps and 3300fps, the .270 WSM is capable of delivering high shock for impressively fast killing out to ranges of around 300 yards along with clean but sometimes slightly delayed killing out to 400 yards. After approximately 500 yards, wound channels become proportionate to the expanded bullet.

223 bullet drop chart

The best way to generate that chart is by shooting over a chrono and inputting the data into an external ballistics calculator, such as this one by Hornady:

Ballistics Calculator


It takes some work to gather the data, but it's much more accurate than any generic chart can be. I've used cards generated by a couple of different online calculators and have gotten better than acceptable results out of them with both my match barrelled 5.56 AR carbine and 7.61x51 Savage 10FCP. Good enough to ring 6" steels at 300 yards and 500 yards, respectively.

There are many other web-based calculators that can do the job, just search for "external ballistics calculator" for more.

Winchester powder load data

Going by the Lee reloading manual, IMR 7828 is not an option for a 150 grain bullet. That powder does not come up in the load data until using a 195 grain bullet. Most powder manufacturers have extensive load data on their website. I would recommend looking there.
