I've gotta HTG Suppressor (w/ permit) on my .308 to shoot long range, and heard that they affect your bullet drop, but I can't tell the difference. Do any of you have suppresors. It sure is nice when your shootin alot. the only thing Ive found is when it heats up, it make a huge mirage right in front of your scope.

A properly fitted suppressor, like a properly fitted muzzle brake won't affect the trajectory of the projectile. Both either redirect or trap the escaping propellant gases to reduce recoil, and in the case of the suppressor to also reduce the noise signature.

Suppressors sometimes change point of impact, just like changing the grip on your gun can change the point of impact. Most modern suppressors do not change the actual ballistics of the round significantly. The only suppressors that do to a great degree are wiped suppressors and suppressors that incorporate ported barrels.

Muzzle suppressors do tend to increase the muzzle velocity a small amount, typically 25-75 fps from what is called "freebore boost". This is not that significant when we are talking about a round with a Mv of 2,800 fps.
