Re: reloading the 300 RUM
While waiting on my backorder for the new Nosler 210 gr ABLRs (Iím not holding my breath), I worked up a load for my new 300 RUM using RL-33 and 200 grain Accubonds. Yesterday it put 4 into 1.25Ē at 200 yards. ES for the first three of those shots was 3. The 4th shot slowed down and made the ES 38. The 1.25" was all vertical spread which was kind of weird. Iíve never seen a load with no horizontal spread. I would have rather had no vertical but it is what it is.
Anyway, this load (99.0 grains) is running 3,140 fps out of a factory Savage 26Ē stainless barrel. Iíve got more room in the case and have no pressure signs so I figure I can probably get to 3,250 fps which would put in on top of the list if RL-33 were covered in Noslerís latest handbook. My point in mentioning this is that RL-33 seems to actually be pretty good for 200 grain pills in the RUM not just the 230 grainers. Oddly though it sucks in the 338 RUM as you run out of case volume way before it pressures out.
