Interesting gun. Ruger is into a lot of stuff these days. I will put a watch on this thread. Maybe you can report back with some shooting impressions. Probably not seeing this or a big 50 in my future, it will still be an interesting read.

I think the bubble level would work better hanging off the rail to the left and be seen by the left eye. Fair warning I got one that mounted that way and total POS. Maybe you got it right, simple.

I hope the S&B brass is ok. I would kinda be thinking anyone but. You plan to anneal, which I read often suggested for S&B. You will want to neck size. Probably try and get a sizer and expander that minimize working the brass. No specific maker just something to research if you not already. And maybe a precision seating die from Reading, if they offer one? None of this will be cheap. Then you know that already.

 

Thanks so much for your reply. Nice catch on the level bubble. I was blessed with a partially developed retina in my right eye. This is not an issue with handguns, it's right-handed for those. Rifles must be lefty for me, so the bubble goes opposite of the dominant eye. I did choose an ambidextrous grip in case my buds want to take her for a spin. I always like to have some factory ammo on hand for everything, so I figured S&B was good enough. For reloading I went with GWT. They are supposed to be the whole cheese for 338 Lapua. Here's some info on them.

Go West Trading Brass (GWT) is precision manufactured match grade rifle brass that exceeds Mil. spec. requirements. GWT brass is manufactured on state-of-the-art equipment right here in the USA. Peerless manufacturing process, peerless quality control.

Neck sizing will be the way to go, it's not like I would have two of these!

Going to function test it at my indoor range tomorrow for giggles. Will have to sight it in a few inches low as it's only 25 yards! On Thursdays management allows you shoot anything up to 50 BMG and everyone enjoys seeing the new patrons scatter from the reports. I have access to a 200 yard range although that is still just spitting distance for this round. It will be mostly for fun like all my firearms. It's not a cheap hobby for sure and I am truly blessed in my retirement. I might have to hire a gun bearer for this beast down the road!

 

Congratulations and welcome! I also recently joined the long distance club and learn more and more each day and with each article I read/each video I watch. YouTube has become an excellent resource - lots of great shooters and knowledgeable out there. What scope are you using on yours?
I went with the Savage 110 but struggled between it and the Ruger. My two friends both got the Ruger and it’s sun exceptional piece! I did get a Vortex bubble level s as d mounted it on the left side of the scope. I’m happy with it there. I’ve seen where guys go a little “gear crazy” with buying a mind mounting accessories all over the rifle simply because they make accessories for the rifle. Just keep it simple and add things that you think will be productive.
Here’s mine (old photo from when I first got it):

 

Howdy!, Lovely rifle, I see a picnic table was your option too for a photo shoot. They are beasts!

Here's the optic I went with, figure it will work out well as I have a lot of catching up to do in its use.

I don't plan on any additional items to hang on it. I went through a phase of that early in my hobby. If it had an empty hole I had to fill it. No more, I ruined the slide on my Beretta 92SB putting an after-market sight on it that required gun smithing - with immediate buyer's remorse. It no longer fit in any dedicated holster. It took me at least 25 years to find an unused slide to replace it. I kind of redeemed the old one by leaving a threaded barrel in it and change it out to play around with sub-sonic stuff.

 

Congrats on your purchase, I have the same rifle.

I've shot mine out to 1100 yds and it's a beast. I've been reloading my own rounds with Hornady ELD match 285gr with 88.1gr of Retumbo powder and match grade primers. I reload Hornady and S&B casings as well as load new Lapua casings.

I had to purchase a separate press (Lee Classic Cast) just to reload the 338 LM since it's too large for the progressive press to handle.

With regards to a bubble level, I'd highly recommend getting a SendIt electronic level. They are expensive but well worth it if you plan on doing LRP shooting. They are normally mounted horizontally, but if you purchase a separate mounting kit, you can put it vertical; it reads the cant setup both ways.

I personally wasn't a fan of the factory furniture, so I replaced them with a Magpul PRS Gen3 stock and AO Penguin grip. I also replaced the factory brake with an Area 419 hellfire brake. The factory brake is odd with where they decided to put the ports and it isn't optimal for recoil control.

Here's mine.

I like that butt stock.

Ruger took me by surprise offering this 338. Did Ruger develop a new longer action to handle this or is it the same bolt and receiver as the 300wm?

 

I took it to the indoor range today for a function test. Fired it from a Sunwayfoto tripod and clamp. It rocks for sure but was a pleasure to shoot. As I said previously on this short range it was only spitting distance. My reloads are Norma 250 grain JHP, GWT brass, 75 grains of IMR 4350 and Winchester WRLM primers. The target is a five-shot group. My buddy also showed me a body armor plate he shot with 338 Lapua Magnum, Wow!

I know this is just first day out for function test from a bit unstable rest, but still, what was the distance?
