That's crazy fast for a 210! I can't get 3050 out of my 300 Rum with the 210
Been meaning to respond to this post but forgot about it since I last saw it on my phone...
The 338 Norma was developed specifically to compete again the 338 Lapua, but with a 26" barrel and was intended to be able to run off of a standard Remington 700 action (provided you have the .590" bolt face). This resulted in a shorter fatter case that is not limited on bullet seating depth in a standard long action. Measuring COAL from the bullet Ogive on my 300 Norma is actually a few thousands LESS than my 280 ackley improved!
Jimmy Sloan was the main guy behind developing the 338 Norma (there's actually plans in the works for a full auto 338 Norma for the military!) and he along with a few others were 5+ years in the R&D phase. It was designed for military application and has slowly trickled into the civilian shooting world the last few years. There's still not much data on it, but it is the most efficient 338 chamber on the market today. Definitely not the fastest, but it is inherently accurate and more efficient than the 338 Lapua. The only issue with running them out of a factory BDL style bottom metal is you can really only get one round in the magazine giving you a 2 shot weapon. They would be ideal to run off a detachable magazine, but would require the 5 shot AICS mags and unfortunately they stick out a few inches below the stock line and are not very low profile for hunting applications. I've been talking with another manufacturer about developing a low profile 3 round AICS style magazine to fit a detachable bottom metal and hopefully we're getting something in the pipeline for that option. Would be very slick to have the option to go with a 5 and even 10 round magazine when not hunting with the 3 round magazine.
We're getting around 2800 FPS using a 300 grain SMK and 92 grains of ramshot magnum out of a 26" barrel. The Vihtavouri N570 powder is supposed to be THE powder for these guns but it's very hard to find right now. Compare that to the 100+ grains guys are using in the Lapuas and often 28'+ barrels, for hunting the Norma is a no brainer decision in my book.
As far as the 300 Norma goes, I'm pushing 185 VLD's almost 3400 fps out of a 27" Rock Creek barrel! Going to be working up some 210 berger loads this weekend and will update that when the time comes.
