Not to hijack the thread, but to answer the 129 ABLR question, I am using H4895 per Nosler 6.5 Grendel load data. R7.5 primer, Hornady brass, 2.26 coal, 129ablr, 18 Lilja barrel AR.
26.1 gr 4 shot group of 0.66 (0.62 vert.)@2250/s
26.3 gr 4 shot group of 0.95 (0.36 vert.)@2266/s
(I dont recall why I only went with a 4 shot group! Maybe since Im running low on H4895!!)
And yes, you need to get your seating die machined to match the bullet since these are rather hard to seat to length and will put a ring on bullet. (Compressed) As suggested I will try rotating bullet during loading next try.
Also, 129 ABLR is 0.6 group in my 260 rem. This is with a trued bolt action and match grade barrel.
