newb reloading question

[5RWannabe]

shooting 308, with LCLR 04, RE15, Fed 210m, and an assortment of Hornady BHTp's

why do my 178's end up a bout 6 inches to the right if i zero'd my remmy 5r with the 168's. does the tighter fit (longer bullet more surface area) and rifleing grab it that much? (at 100 yards)

i have noticed also that with anything higher that a 168 i have to be sure to hold on tighter as the grip trys to rotate counter clockwise out of my hand (only really noticed that on a bag and not a tripod). i just assumed it was because of the heavier bullet creating more friction or something.


i know i need to work on the fundemantals, of cheek weld and proper relaxation, but maybe i get to relaxed?

Different bullets will cause a different "Vibe" in the barrel. One of the tricks to reloading ammo that *Mostly* will impact in similar areas even when the Load is different, is to use the OCW method.

It really is amazing how different loads can shoot so utterly different at times.

The load recipie for the 178s and some characteristics of a) your gun and b) that bullet have conspired to alter the "barrel harmonics". That is, each shot, the barrel whips to and fro in fractions of a thousands of an inch. Yet those fractions of a thou are enough to alter the course of the bullet by a pretty large distance. It is only after you get beyond 300 yards that <exterior> balistics has a bigger determinant of where the bullet lands than this whipping around of the barrel.

Heavier bullets create a bigger torque as they get spun up to 300,000 RPM. You are feeling the guns reaction to this torque.

But it sounds like you are tryinig to shoot "free recoil". You can get away with free recoil in something small like a 223/243 but when you get up into the 308 range you really need to develop a grip on the gun that allows the gun to recoil directly into your shoulder while remaining under control in your hands at all times.

Re: newb reloading question

Just a suggestion, maybe a good shooting school to review or maybe learn the basics. Folks that teach the art of shooting can quickly pick-up any flaws and make suggestions to correct. It's amazing how the smallest things with grip, trigger control, cheek weld, etc. can impact POI. It would probably save alot of $$ in bullets, powder and brass in the long run.

Just my $.02.
