Here are my LR rifles.
From L to R, 7mmRUM (150ET), 300RUM (200AB), 338RUM (250AB), 375RUM (260AB):
I am considering a thumbhole stock for the 338RUM though, dang thing kicks like a large mule, needs a little more weight to it, plus the XCR stock is not much for eye candy.
Greg, here's my 7 RUM recipes:
Bullet Powder & charge Primer COL Brass & Trim
150ET Retumbo 91 GM215M 3.655 Rem 2.83
160AB Retumbo 91 GM215M 3.635 Rem 2.83
Regardless of magazine length, there's no way I can get the above two bullets even close to the lands on my Rem 700 SPS...
I have a 375RUM, it's the Remington LSS model (laminate stock, stainless). It is a tad heavy, not quite as much as my thumbhole stocked 300RUM, but I find it just as easy to shoot as my 300RUM. My 375RUM is pushing 260ABs at 2990 FPS.
My 300RUM has become pretty much my main rifle. I like how it feels and it's easy to shoot, but does get a little heavy at the end of the day though.
Wow, looking at picture I took, I've had it 9 years now..... :shock:
I'm going to develop a load next spring using Nosler 338RUM brass and 250ABs. Managed to get 200 pieces of their 2nd brass through SPS. Dang spendy stuff..... :shock: :shock: :shock:
Lot of good info here. I've contemplated getting some 30 Cal 190 ABLR 2nds from SPS to try in my 300RUM, but I keep thinking why???? The 200ABs have performed exceptionally well, every animal they have hit has gone down quickly. Why mess with something that works? Plus, where I hunt and shot all...
You're going to have problems shooting a 6.5mm bullet out of a barrel already made for a .277 bullet. Also, when did Nosler come out with a 27 Nosler? I know of the 26 & 28 Nosler?
Since I own and load for all 4 RUMs, I can say that the magazine is the limiting factor for OAL on all four. In fact, with my 7 RUM, I can't seat the bullets out far enough to touch the lands even if the magazine space would allow it. The longest OAL I can get is 3.67" and still function...
I've only used Nosler brass in 30-06, but haven't had any problems seating GM210M Fed primers. Time will tell if I have issues with my 338RUM brass I just got.
