Thread: Trying to be a bit precise

Hi all,

Bought a new scope rings rail etc to try to stretch the legs out on my .243. Bore sighted it, got it on paper, shot a 3 shot group, taking time between shots to check target (200m).

First group was 17mm and great for elevation, though 1.5" to the right. 3 clicks left to take it to center, next group was great for windage but 1.5" high????? I double checked that I had turned the correct knob as was my first thought.

So two questions;

1,Could this be things heating up shifting the group?

2, I have not done any load development for the rifle, I just load 95gr sst at max load and F/L size. I can see there may be some gain in neck sizing, is there anything else I should be doing? Less than an inch consistently at 200m is great to me, but I read some of you guys are doing amazing things, should I push this further?

Thanks Lars
