Howdy Fellas,
I got my scope mounted on my .50 Alaskan T/C Encore pistol. The base had been put on by the barrel maker, Gary Reeder. I mounted the scope and secured the ring screws with Blue Loctite. After 11 rounds, the base started shaking. Honestly, I wasn't too surprised. I pulled it off to find some Red Loctite and some strange translucent goo. I'm guessing something didn't dry.
I talked to Gary and he didn't know what the goo was, but said sometimes this round will shake free of even Red Loctite. He said it may be necessary to epoxy the base on.
All I had was Blue Loctite, so I gave it a whirl. Shockingly, it held up a touch better, and after another 19 rounds, its time to again re-affix that base.
So what do you fine gentleman suggest? I imagine many here have dealt with rifles and handguns that could shake a scope base loose. Bradshaw? Lee? Max? JT?

Epoxy or better yet, consider SSK T'SOB.

Yeah, there's any number of six hole bases. I bought the other 50 Alaskan barrel the day you bought yours. Got Gary to put two more holes.

Loctite 638 Green between the base and barrel. It is a bearing retainer. I have had really good luck with it on alot of light weight, high recoil rifles.

I’ve never shot my TSOB loose on my Alaskan. I’d check to make sure the screws aren’t too long and not letting it really bite well. The goo almost sounds like the crap on loctite if you don’t shake it up. GS

I think you've heard everything: 6 screw base, preferably by SSK, proper length screws, red Loctite or epoxy. I use red Loctite, with no problems.

If I move to a 6 screw picatinny I'll need new rings. I'm surprised Gary gave me a four screw base. I assumed he would have given me the best base for the round.

A four screw base seems optimistic on that gun. With 650 grain BMG bullets, recoil is “snappy”. The six screw and the lightweight rings work great.

I just spoke with Mr. Reeder. Hes recommending epoxy on the base and Red Loctite on the screws. So it shall be!

I just can't get behind epoxying a base personally. Even on my heavy recoiling rifles, if you even consider putting epoxy on a barrel or receiver, you need a different base and more screws. I have no epoxy or loctite on anything honestly. You should never have to epoxy anything on your gun in my opinion...

What are you using for a base and rings? People think steel means strong. But it also means a lot more weight/mass you're trying to hold on with little tiny screws. Aluminum is what you want if it's not what you already have.
(coming from a guy who's dodged a flying pistol scope or two in his day and not always on stiff kickers.)

Aluminum is what you want if it's not what you already have. (coming from a guy who's dodged a flying pistol scope or two in his day and not always on stiff kickers.) So, I have a Leupold, steel, 4-screw base with Leupold rings. I asked Gary about going to a 6-screw base and he said it was unnecessary as he has harder recoiling rounds on the same base without issue. He also commented that he feels aluminum is a no-go and said that it was not sufficiently strong. I have no dog in this fight as I feel both you and Gary know better than I do. I'm still scratching my head and trying to decide which path to go.

I have no epoxy or loctite on anything honestly. You should never have to epoxy anything on your gun in my opinion... I'm not disagreeing or arguing, I'm just the noob who's trying to learn. But just to share, here's what Gary was recommending. He stated that six screws was unnecessary, and the Leupold base he put on it should be fine as it works on other harder recoiling rounds he uses. He's also not a fan of the aluminum bases. He was saying the epoxy should be far away from the screws as this would make it impossible to get the base off in future if I ever want to. He then told me to use Red Loctite on the screws, as the Blue wont cut it. He also didn't like the Green Loctite idea. I believe both of you have sufficient experience to know what you're talking about, I just am stuck in the middle. I don't mind the idea of epoxy or Red Loctite on the base. The ring screws haven't budged with my Blue Loctite and those I don't mind occasionally redoing. For me it's just a lot to consider and about which direction to go in.

I had a steel Leupold base and rings come flying off on a .357 mag barrel.
Steel mount left my 358 JDJ pretty quickly as well, though a little more understandable.
After that I wouldn't use them on anything larger than 222 / 223.
I put a 6 screw aluminum base and three ring setup on my 358 JDJ and never a problem again.
I have an aluminum (epoxied down) 4 screw base and three aluminum rings on my 309 JDJ also without issue.
I mention those because they kick well and I have MANY rounds through them. I've also "owned" a 308Belm, 257 Roberts with aluminum setups. I had them long enough to shoot up the ammo, then sell for my sister. They'd belonged to my brother in law who'd used them for years, also without issue.
Check your screw holes and make sure they're not stripped or egged out. If so they will never hold. That's what happened to my 358 JDJ barrel.

I’ve had the leupold come loose due to weight and also it’s holding force for scopes on a heavy recoiled never impressed me on the FA guns. I’m not telling you what to do but what I have done and not had issues. I do not use loctite on any bases or rings and definitely no epoxy so it just makes me scratch my head when someone is given that advice. That’s all 😊
