35's
I have been playing with 35's for over two decades now. First up was a 358 Win and a delightful little thumper it was. Recoil in a 7 pound rifle was fairly mild and hitting power good. Unfortunately when I moved to Nunavut I had problems at long range. The rifle was subMOA accurate and I could make hits to 300 yards but the stout spitzers didn't expand really well unless I red-lined the cartridge. It was a fantastic Arctic hare gun believe it or not being a quite bit less destructive than smaller faster bores. Some of the loads people report using in this little round are definately high pressure! Factory normal pressure loads gave me no more than 2400ft/sec with 225 grain bullets in the 20" barrel.
This took me to the 350 Rem Mag and the extra 200ft/sec made a good difference in long range hitting power. The 350 shoots about as flat as the 308 Win but with 25%-30% more bullet weight. Very good cartridge and the kick with the 225 grain bullets is not so bad. Seems to me the 225 Nosler partition at 2600+ is the all-round choice for this original short mag.
When I moved down to the NWT I saw the size of Moose and figured that past 200 yards I'd like more thump than the 350 Rem Mag delivers. I moved up to the Norma and it will do at 300 yards what the 350 will do at 150 or so. An extra 200-300ft/sec over the Rem Mag depending on bullet weight definately puts this baby in a different class.
I have two Norma's a 7 pound Ruger that is magna-ported but still kicks like a mule. Did some load testing this weekend and groups from it and the best load went .85MOA (250 Nosler Partitions-2750ft/sec) and the worst 1.6MOA (250 GrandSlams). The 22" Ruger barrel copper fouls like a bugger and needs to be cleaned often but it shoots and carries well. Prone is a bugger but the decellerator pad helps a lot and sitting it's a pretty easy gun to control. 20 rounds is my limit for a range session and I need 3-4 days to let my shoulder heal. However when hunting you never notice a thing.
From the vehicle or other conveyance I like my Douglas Barrelled Sako. It is a 9.5 pounder with scope and the 25" Douglas Premium Barrel has made honest 0.5 MOA groups with the right bullets (250 Speers or Noslers). It gets 100ft/sec more than the Ruger and the faster 14" twist and longer magazine box lets 275 grain Barnes Spitzers (I have about 300 left) at 2700ft/sec hit like a truck and shoot inch groups while doing so. Basically a 375H&H in a different guize.
You can't go wrong with the 35. The bullets range from 150 Core-Lockts to 300 grain Barnes O's (if you can find them-I won't sell mine ) pretty much covers the range from antelope to elephant. It's definately at it's best balance in the Norma but the smaller versions are useful too. Even the 35 Rem has a place.
That 358 STA is a scary monster though.

This is an article that both Ted and Rick gave me a hand with a while ago. Since then I have stumbled on to a bunch of 275 Barnes Originals and they perform very very well. I'll rewrite it when I have downed a few moose.
