SOURCE: Bushnell Sportview rifle scope wide angle 4x38 T4389 limited adjustment inconsistant results

Hello,
I had the same problem but was able to solve it by shimming the scope mounts with a thin piece of plastic. Put it under the rear to raise the sighting and under the front to lower. I still plan to buy my son a better scope.

SOURCE: lost manual for trophy scope 3-9x40 rifle

There is no manual for elevation and windage adjustments. (at least not one that comes with your scope; all your scopes manual will say is whether its FFP or SFP (First Focal Plane or Second Focal Plane, the scale used on your scope for mil dots)(you can get this info by finding a store that sells this scope and asking a sales rep)

To adjust for elevation and windage you have to take into account the daily factors (unless your shooting in the same indoor environmental controlled shooting range each day you SNOB! jk

The formula takes alot of variables into account and is known as Exterior Ballistics

!) Environmental Factors - First thing you account for.

A) Elevation from sea level plays a large part into your environmental adjustments. Your elevation from sea level determines largely the Barometirc Pressure but it also varies slightly with Temp and Humidity (Major Factor)

B) Temperature - The temperature can affect the density of the air. The hotter it is the thinner it is and therefore less resistance and a higher bullet trajectory (Minor Factor)

C) Humidity - This again will affect the densify of the air infront of your bullet (Minor Factor)

D) Barometric Pressure - The other large factor in air density this is the base stat that the others modify

These all combined create a ratio that you apply to standard MOA (windage and elevation adjustments) to obtain the shooting information for that particular environment)



2) Bullet Factors (Listed on the Box you buy) - There are a few bullet factors to take into account.

A) Speed - the bullets feet per second can vary as much or more than 500 feet per second with the
same caliber ammunition.
B) Grain - The Grain of an ammunition is a measure fo its "Sectional Density" or weight to volume
ratio
C) Ballistic Co Efficient - This number is the measure of the bullets ability to maintain its speed
during flight. This also varies from Grain to Grain


These factors are complex and a pain for the best of shooters to determine. adding to that confusion. there are many ways to determine a bullets ballistics coefficient and each one gets a different number. In this case bullet data is best retieved from the manufactuerers box and take their word for it.

3) Lastly you account for shot factors.

A) Range - by referencing your standard elevation MOA adjustments and mutliplying by the ratio for environment the Elevation MOA is achieved.


B) Windage - Windage is done in inches per mile per hour then is multiplied by the Mph of the wind.
In order to be precise the windage is done in inches instead of MOA. it needs to be converted heres and example.

You Ballistics Cheat Sheet for the day says the windage at 900 yards is 5.2 Inches per mph of wind.
you apply the ratio for your environment .90 (all example numbers. this number would represent a shooting environment with an air density lower than standard/ the cheat sheet's known MOA adjustments). the 5.2 inches is multiplied by .9to acheive 4.68?? idk the point is you mulitply that by the wind of 10 mph to achieve a total of 46.8" of wind drift to the target.

now for the conversion to MOA. 1 MOA is eqaul to 1.047" per 100 yards. meaning for every 1 moa you adjust the bullet will move 1.047" per 100 yards (our target is 900 yards; meaning that each MOA for this target is 9*1.047" = 9.423" per MOA adjustment. so take that number and divide our total wind drift by it. ie 46.8 / 9.423 = MOA Windage Change of 4.9665... now you need to know whethere your scope is 1/4 minute clicks or 1/8 minutes (how many spaces between large numbers?) you would adjust to 5 MOA for a 1/4 minutes scope equaling 20 clicks on an 1/8th minute scope it would be 40 clicks.

This is the math of shooting. to learn how go to
WWW.shooterready.com they are an excellent sight to get the math down WITHOUT wasting ammo. Once you have the math you an transfer it to your gun. waste a few rounds checking it out and youll be hitting targets @ 1800 yards in no time

I like to take the simple way after i learned how to do the hard way

There is software tha will do the exterior calcualtions for you.

if your interested i use Sierra Infinity V6 Ballistics Software

SOURCE: What types of ammo can I use in a .35 Remington

If the powder burn rate is incorrect, you can pull case heads off in a Rem auto.... bolt tries to open too soon..using IMR 4350. the pressure curve is not right, too much gas pressure when the bullet passed the ports. Same loads shoot perfectly in a bolt gun, very accurate, actually.

If you are going to reload, I'd stay with powders in the burn range of 4064 or 4895, single-base stick powders, faster than 4350. Bullets should be the lighter range.. perhaps 150 or 180 grains. With the faster powders, the pressure curve should be correct.
Honestly..... give some thought to a plain old yellow/green box of Rem 200gr Cor-Lokts... generally available off the shelf and should do the job fine. Sometimes we get carried away with our reloading efforts when there is an inexpensive box of factory ammo that will do the job, especially if it's for a non-reloader who needs advise.
lso, the semi-auto and the pump type centerfires require the use of SMALL BASE reloading dies to assure proper chambering. Sometimes, regular FL dies will not size the case down far enough for reliable feeding.

Tip

Sight in your scope


I have given this tip to a dozen people this week. It will save you a ton of ammo. If you don't have a bore sighter of access to one, get a big cardboard box, cut V's in the top that the rifle will sit in nicely, remove the bolt. Find a target, 100 yards away, sight down the bore, tilt box, rifle to target, make sure it doesn't move, adjust scope to the same target. check to see if the rifle is still on, then check the scope again. This will put you on paper at 100 yards.

I have an airweight 38 does it hurt the gun to dry fire?


It won't HELP it, that's for sure. Go to a sporting goods store and purchase what's known as "Snap Caps" for your weapon's caliber. They're small plastic "ammo" that has a spring embedded where the primer/igniter would normally be located. When you dry-fire, the spring provides the proper resistance to the firing pin, preventing over-extension and premature wear/breakage of the pin. They're cheap, and since you have a wheel gun, you can load 'em once and shoot again and again and again. https://www.amazon.com/Tipton-Snap-Caps-Special-Magnum/dp/B0048KFHKQ/ref=sr_1_2?s=sporting-goods&ie=UTF8&qid=1491493949&sr=1-2&keywords=snap+caps+.38+special

Harrington richardson arms


You didn\'t state what make, or type (pistol, revolver, rifle or shotgun) of H&R you have, so I can only give generalizations.



As a general rule, centerfire rifle\'s and handgun\'s firing pin protrusion usually measure between .050" and .060".

Shotguns are a little longer at .055" to .065".

Rimfire guns usually fall into the .028" to .035" range.





Once you have established that the firing pin protrusion is within an acceptable range, you can get a rough idea of hammer spring strength by looking at the primer on some fired rounds for how deep and pronounced the indent is.



Also, you mentioned that some brand(s) of ammo fired more reliably than others.



Some ammo requires a harder "hit" from the firing pin to ignite the primer.

This has to do with factors such as the alloy composition of the primer "cup" (some are harder than others, requiring a harder "hit"), some primer compounds are more sensitive than others, etc.



So maybe experiment with different brands and see which ammo works best for you.

How to sight in a z6 swarovski scope 10x42


the easy way is bore sight it,,,,,first clamp the rifle in a stand and look down the barrel at some thing like a post top at say 100 yds when you see the post top in the bore dont move the rifle any more till you have tweeked your scope so the cross is on the top of the post top,,,the rifle is then bore sighted,,,now clamp the rifle down and test fire it,,,it will likley shoot low,,,so tweek it till it shoots right,,,,you should get it spot on in less than 5 rounds,,,dont try to hand hold your rifle when zeroing,,,you need to get rid of as many wobbley bits as you can,,,gees whats the bigest wobbley bit?,,,,yep we are? so clamp it down till it shoots right! also dont fire more than 5 shots or you will get your barrel hot and this changes the point of aim,,,in a sporting rifle???

How to load and clean and ammunition size for a mossberg 146b 22 s lr.


OK, your rifle is a bolt action 22. I can't find the146 but I have a 144 here. You clean the bore with a small rod and patch with solvent on it, run down clean patches till they come out clean, wipe down the metal parts with solvent, then wipe down everything with a patch lightly soaked in oil, run the oil patch threw the bore. Your ammo is .22 LR, If you have a magazine in the bottom of the gun, fill it up and pop it back in the rifle, if it is a tube magazine, pull out the tube, fill her up and close it up. Pull the bolt back, release the safety, and keep it safe. @22s are powerful little bullets.......
