Little range time 6.5 x 284 / 143 ELD-X

[Bush Stalker]

H4831sc is a slow powder, I'm 3.2 grains over Nosler book max to get 2890 fps. When I was using max charge in the Nosler manual, I was barely pushing 2700 fps and that was slow. My 6.5 Creed does 2800 fps with H4350 . The slow node with the 6.5 x 284 which made one hole groups was with 48.3 grains and it was at 2650 fps. The faster node is at 52.2 grains, and shoots .25 MOA or better @ 100 with the ELD-X. I ran it up to over 2920 fps, but accuracy was not there at that time, but I could spend extra time with seating depths to find it, but did not want to waste too much time with it when its a .25 MOA hunting rifle. I could do better with Bergers, but prefer the ELD-X over Bergers for hunting, but hey, I still have 10 boxes of 140 Ballistic Tips to try in the future and some Accubonds.

I'm looking to develop a 6.5x284 Norma load with the 142 ABLR. I've had phenomenal success (sub moa) with 57.6gn of Retumbo and the 140gn Nosler BTs @ 2989 fps ave. Primers are flattening a bit but no obvious pressure flags. Lapua brass. I have yet to try the ABLRs but getting very close to a range visit. I loaded the ABLRs with a similar Base To Ogive measurement as the BTs resulting in a COAL of about 3.045".
Was wondering if you had any data to share.

Btw, my 300wm loves 165gn bullets sitting on 72.5gn IMR 4831 singing along at just over 3000fps. 180gn pills are a bit slower at just over 2900fps and 70ish grains of same powder. I could push them a lot more but there is no need to. Rifle happy. Me happy. Animals dead. LOL

Thanks!
