Just disasembled my Ruger hawkeye base and getting ready to clean/reinstall it and a Masterpiece arms 34mm one-piece mount. Ive been using blue loctite most of my life but Ive heard some now saying that purple, green and yes.......even RED loctite are better for these applications because of the violence recoil entails. This is on a fairly heavy (roughly 15-16lbs) 6.5 PRC with a muzzle break. Sounds like my ex wife when she didnt get her way when it goes off but the recoil is honestly not bad at all. But theres still that Ex wife-ish concusion from the blast. Is there a better option than blue loctite? Are these others better suited or maybe even somthing else? Stick with the blue? I shoot quite a bit of long range and prefer my stuff to stay as solid as possible.

Thanks,

Kevin
 
Proper torque and witness marks no Loctite. Go shoot it and not abuse it but use it. See if anything moves, if it does a small amount of blue.
 
Clean threads, blue Loctite and the correct specified amount of torque applied via a torque wrench should be sufficient in 99% of applications. If it's not, then the products are defective and need sent back to the manufacturer. I would not use those other Loctites for this application.

Dogpiling on. Degrease the threads, use a very small amount of blue Loctite, torque to spec, and let cure 24 hours before shooting.

Not all blue Loctite is the same. 243 is the oil-resistant formulation. 242 is more likely to be affected by solvents and oils.

You know. Ive been wondering about exactly what you just said. I think im going to do that. Im also looking at putting a .008" shem under the base as well this time to gain some elevation. Im really hoping all this comes together well.
 
PSA from Ken Farrell on base bedding; the Loctite retaining compounds can bond very thin clearances and are made for cylindrical / round fitted parts.

  • MOUNTING FARRELL SCOPE BASES AND RINGS- For those who wish to mount and maintain this flatness, we've provided a bedding groove (a first) on the underside of the mount to allow a dense application of epoxy. It is common, but not always necessary for rifle receivers with steps such as Remington 700, Mauser 98, Pre-64 Winchester etc., to possibly need bedding material on the rear where they have been polished or ground excessively. Round top style receivers rarely will need any bedding.
 
I bed my bases with blue after decreasing with acetone.
Haven't had so much as a shift on any of them.
 
In 20+ years of professional racing we never, ever used blue on anything smaller than #10, usually purple for #10 and under. Properly cleaned, decreased (extremely important on new hardware) and torqued to sae spec for fastener size, pitch and material yields best results.

This! ^^^^^^

Clean threads, proper torque and fastener stretch goes a long way towards proper assembly.

I always use white fingernail polish on my small gun fastener threads. Its cheap, it works, and is easily obtained at Dollar General stores coast to coast.
I shoot in a lot of different climates in all kinds of weather.
Never had one single failure. Ever...

Proper torque with a good linear torque wrench is paramount to achieving good results.
 
HOW TO CHOOSE A LOCTITE® THREADLOCKER

WHEN CHOOSING A THREADLOCKER, THERE ARE FOUR THINGS TO CONSIDER:
1. STRENGTH
• Low Strength (Purple): Ideal for fasteners <1/4" (6 mm). Easy disassembly using hand tools

• Medium Strength (Blue): Designed to be removable with standard hand tools on 1/4" to 3/4" (6 mm to 22 mm) fasteners

• High Strength (Red): Designed to deliver high strength on 1/4" to 3/4" (6 mm to 22 mm) fasteners. For removal, it may require localized heat (>550°F)/260°C) hand tools, and disassembly while hot

Thanks guys. Using everything youre saying. However i may be more confused as well. Lol

All of this is great advice and information!
