Anyone have experience with the 300 Norma Mag
Surgeon is now building this rifle
I have shot several & made 3 different Wildcats from it. I'll try & help with any specific questions you may have. The parent works very as is. I thought it was a very good substantial case to base a 7mmXR, 300XR & a 338XR off of. What has worked the best for me is Fed. 215M primers. Retumbo & N570 is your friend. I have not pushed the calibers very hard. They started shooting very well right off the bat so I just didn't search out a maximum load. The 7mmXR is 10.4" high at 100 yards will put you on @ 700 yards. The 300XR spits a Hornady 208 AMAX out at an avg. for 20 shots of 3157 fps. I don't remember what the 338XR does. I just shot it enough to see that it was going to be a shooter......it is.
Thanks for the info, I am excited about this new rifle as Surgeon builds a great gun.it sounds like you have great luck with Retumbo and N570, I have heard that from others.
The Norma brass is expensive but very high quality. What did you use for bullets.
The only two bullets that I have tried are Hornady's 208 AMAX & Berger's 230gr. Hydrid. Excellent accuracy from both. I would shoot either or in a match. I'll try Lapua Scenar 155gr. in the near future. I plan to shoot all three in out 1000 yard matches by the end of the summer.
Hornady 225's shoot very well also. They and the Berger 230's will stay with the 338's at ELR.
Thanks, I will give Hornady a try. The long range shooting is interesting and challenging. We have been done a lot of shooting in the AZ desert, lots different western North Dakota.
I haven't built myself a 338 Lapua yet as I've had so many through here for testing. I'm about to and there will be an extra barrel, 300 Norma. I love big 30's for LR shooting.
I have had a 308 Norma Mag rifle since the 60s. Never have heard about the 300 Norma Mag. How are they different??
308 Norma is a long neck 300 WM, .532" rim and the 300 Norma is based off the 338 Lapua diameter case.
Have you had any experience with Surgeon rifles?
I have my own action made for me by Stiller so I don't use their actions. But yes I know them well. Our paths cross in other endeavors. Good bunch. No worries.
I predict a .300 Norma Magnum barrel that starts out shooting 1/4 MOA at 100 yards and 3/4 MOA at 1000 yards will do that for no more than 600 rounds. Maybe 700 if one's lucky. That's a way, way over bore cartridge.
If so I would not be interested, kinda hard to get away from 300WM for me, however that 30-375 Ruger is interesting & may not be too much of a good thing.
If you know how to manage carbon fouling and heat checking you can expect 900 good rounds out of the 300 Norma. The 30-375 is a better balanced round. By that I mean you get enough of a boost in velocity over the 300WM without increasing recoil much, as well as shortening barrel the life. It works with a .523 bolt face VS the need for a custom action for a 300 Norma. It works very well with heavy bullets. I've shot it out to 2K. With that being said there are no free lunches.
