30 cal 197gr GSC?

Anybody used this bullet?



Bullet Number



308197SP204

0.308
.308" Calibers

197gr

Speed
Max fps
m/sec
fps
3,400

BC
0.827







This bullet is recommended for:


Single Shot Feed

STABILITY FACTOR AND TWIST RATE
A Stability Factor greater than 1.2 is required. Any combination of twist rate and bullet length that does not give at least that, is not suitable. SP bullets are non-expanding spitser type bullets and are not recommended for hunting, unless you have a specific application. For use under 500m, a Stability Factor of 1.5 or even greater can be used. For distances beyond 500m the stability factor can be decreased, but must never be less than 1.2. Some experimentation will be required to determine the best combination for your particular atmospheric conditions.
Choose a bullet length best suited to your rifle twist and type of shooting.
Note that S/F increases as twist tightens. A 1:10" twist is tighter than a 1:12" twist.

    If you could get that bullet going 3400fps with the right twist, it would be impressive i bet

    Very finicky bullet and tough to tune a rifle for. Very sub par BC for there hunting bullets. Barnes a much better choice for hunting. Very high BC for paper punchers but it will take a dedicated barrel and throat to get them to shoot well.

    The 3400fps that durak gave in is op is the maximum launch speed of that particular bullet. It does not refer to any load data, only that the bullet should not be launched at more than the maximum speed specified.

    GSC bullets are designed to work in standard chambers. Nothing special is required except that the chamber should be on spec. If the chamber of the rifle is out of spec on the large side, getting accuracy with GSC bullets can be finicky. The upside is that, if a chamber is under spec, as some tight chambers are, GSC bullets are more forgiving of pressure and less hassle than standard bullets. The HV range is designed primarily for hunting under 500 but there are a few HV bullets that are designed as long range hunters and the BC numbers are good. It is always a good idea to shoot drop tables with the bullets you choose because some manufacturers give fictional numbers, some actually shoot and determine BC numbers and some give calculated BC numbers. With BC there is no standard to rely on.

    Contact Anthony at the USA website, he can put you in contact with shooters who have used this bullet.

    Why would you want to shoot a non expanding bullet that is specifically not recommended for hunting as a hunting round?

    Personally I prefer not watching wounded game run off over the next hill.
