What does BDC mean for scopes?
Bullet drop compensation scopes
Bullet drop compensation scopes use a specific reticle pattern to indicate how far bullets drop over a given distance. When we look through a scope, the reticle has multiple aiming points that are stacked under the main crosshair. We can even say that a BDC reticle is like multiple reticles inside the main reticle.
What does dead hold BDC mean on a scope?
The Dead-Hold® BDC reticle is designed around an average ballistic curve, allowing for use with a variety of different firearms. From high-powered rifles to rimfires, windy conditions to calm, the Dead-Hold® BDC reticle will help the shooter put rounds on target quickly and effectively.
Are BDC scopes good?
Low magnification BDC scopes are perfect for general-use carbines like this Sig Sauer 556 Classic. Most shooters are too wrapped up in the mentality that shooting only occurs at even multiples of 100 yards.
Which is better mil or MOA scope?
For the benchrest shooter focusing on small targets at close range, MOA might be the better choice. If you were shooting . 25” targets at 100 yards, a Mil-based scope with . 36” clicks would move you from one side of the bullseye to the other.
Does BDC change with zoom?
Theoretically your zero will be the same regardless of magnification. This is whether your scope if first or second focal plane. For second focal plane scopes (which most of us use) your yardage for each BDC ball will change, with the difference in yards between each ball going down as you increase the magnification.
What is the advantage of a first focal plane scope?
First focal plane scopes have an advantage because they always keep the same relationship between the reticule position and the target position, regardless of zooming between magnifications.
Which is better SFP or FFP?
In general, FFP is great for long range, high magnification, competition, and some professional tactical and hunting applications. SFP is very good for most target shooting, hunting, and CQB performance.
Which focal plane is best for long range shooting?
First focal plane scopes are best for competitive and long-range precision shooting. The hash marks represent the same value across all magnification levels. It allows you to use and trust those holdovers at any given point in your magnification.
Which is better first focal plane or second focal plane?
There is no “better” between the two focal planes. Higher magnification ranges are better in a first focal plane scope. Lower magnification is fine for second focal plane scopes. If you’re into precision shooting, especially in matches, and you don’t mind the cost: a first focal plane riflescope is great to have.
Which is better FFP or SFP scopes?
What scope does the U.S. Army use?
The Army, Air Force, and Marine Corps use the Trijicon TA31RCO ACOG, which has a 32mm objective lens and a 4× magnification (4×32). It is specially designed with ballistic compensating reticles that are also fiber optic and tritium illuminated. It can be paired with the M4 carbine and M16A4 rifle.
What scope do U.S. Army snipers use?
Mark 5HD riflescope
The Mark 5HD riflescope was selected as the optic for part of the U.S. Army’s Precision Sniper Rifle (PSR) program. Not only does the new reticle improve accuracy, but its development within the Army means that costs are saved by avoiding license fees from the use of existing commercial products.
