Id probably say to go with the 120g for a bit more velocity. I have tried the 130g cx in my PRC but ive now given up with it due to extremely poor accuracy across multiple charge weights/seating depths

Hello mate, hm, i cant find that bullet in gordons reloading tool.
However just playing and around and running a load for 46.8grn of n160 , with a 130 grn barnes tsx s, in a 6.5x55 se in a 24 barrel, it gives me:
load ratio: 97, burned prop: 100%, MV: 2837 fps, max pressure: 54558 (so pretty close to the official cip max).

A friend of a friend run it through his quick load system and he has come up with a max charge of 42.4grns of n160 for that particular head …?

Hm, odd, and we're talking a modern 55114 psi of pressure set as max here, right?
But i might have made an error somewhere, i'll check it back again later. This just goes to show why double and triple checking, also between programs + doing a safe build ladder is a good idea though.

Having really struggled to find an accurate factory load in 6.5x55 for my Sako 85 I found that 44 grains of N550 with the 130 grain Hornady CX will shoot sub MOA groups with a MV of 2791fps. 44 gr is near to maximum, so it would make sense to work up to this...

I tried N160 with the 130gn Hornady CX bullet in my 6.5 x 55SE. I worked up from a 36 gn starting load which produced 2294fps and not terrific group size of 1.3". I worked up to 42gn of N160 which produced 2568fps. Accuracy was marginally better, but not what I was looking for.
As I commented before, 44gn of N550 produced average velocity of 2791fps with better accuracy in my rifle. It wasn't an arbitrary selection of that charge weight... I based it on a 130grn Lapua non-lead load using N550. Actually the Lapua load indicated a max safe load of 46.8 grains, but the 44 grains procued good velocity and the primers were getting formed onto the firing pin very well so didn't try pushing it any further.
From checking info on the CX bullets it seems to be important that they are running 2000fps at impact minimum to get expansion which is another reason to use N550.
