Abbey gunlube sm50

[tmstech]

I used 1 drop of SM50 directly into the transfer port of my old BSA air rifles (with leather piston seals) ever 100 or so pellets and never has any issues spanning over 25 years. This was on advise from Neroche Armoury my local RFD at the time. I guess in this scenario the silicone had no negative effects whatsoever, however not used on any other gun parts I would add.

Bowket tells me that he has been using and recommending the use of Abbey SM50 or Bisley Gun Lubricant since the 1980's. He advised their every now and then use in the hundreds of Sharp pumper conversions, his thousands of springer conversions and the pcps/CO2s he has both made and those based on his designs. He has never had any reason to advise against its use providing the small bottles are well shaken before use The proof of the pudding is in the eating. He advised BSA to use it during assembly first on the SuperTen and then all the other BSA pcps based on his designs. Before that in the late 1980's he used it during assembly of the Titan JB1, Manitou and Mohawk for Titan Developments Ltd.
When he carried out springer conversions he advised against the use of Abbey 35 as it was not suitable for metal to metal where Abbey SM50 was ideal for both metal to metal and seals. Lubricant never staying where you want it to.
These facts came from from someone with over 30 years practical experience of using the product not just after a bit of googling or wikipaedia searching.

Bowket is a legend of an engineer in the airgun world of course - but chemist he isn't. Did he just use this product because it was presented to him, he tried it, and it worked, so he stuck with it. Or was there some critical testing Bowket did on the product compared to others, or even more generic products.

On my firearms (powder burners) I like to use SuperLube on metal-metal friction surfaces. It is a synthetic grease with PTFE. They make a synthetic oil too - with and without PTFE. Both very compatible with Nitrile.

"Gun Lube SM50 is the recommended lubricant for high velocity moving parts...." they claim.

So some years ago I tried it on mt FWB P34 striker hammer. It stopped the pistol working! Had to strip and clean. High velocity and silicone oil (or whatever it is that makes SM50 viscous) don't always mix IMO.

Bowkett refers to SM50 as a silicone/moly mix

I always thought Abbey SM50 and Bisley Gun Lubricant were the same thing marketed by different competing franchises. The usage wording is almost identical but the Bisley is advertised as molybdenised silicone oil in several outlets.

The msds sheet for the Bisley stuff is remarkably similar to the one for Abbey including silica as a product of combustion

Found my old Abbey leaflet. SM50 is for piston bodies and piston heads.

This was also confirmed in an article in an old Sporting air Rifle mag from 1985 when the writer said he used SM50 on the piston head and body and LT2 grease on the spring.

Isn't the problem with silicone lubricants related to high load metal-to-metal bearings? Not something you find in airguns but more wheel bearings in vehicles and the like.

I still have my early 80's box of Abbey Airgun Maintenance Kit and contents. It comprises of:

Silicone Gun Oil 35 - Unsurpassed lubricant for leather and plastic washers. The bottle contains a stick-on label in red text; "Not recommended for metal to metal lubrication". The bottle praises its use as a light overall application ensures lasting protection to all metal and wood surfaces and gives a finish resistant to finger printing.

Gun grease LT-2 - I think we are all familiar with that.

Gun Lube SM-50 - A unique blend of silicone and "moly" for metal to metal lubrication. The bottle label gives: Molybdenised Silicone Oil - A high performance oil for specialised lubrication of moving parts in all rifles and sporting guns. Efficient and lasting lubrication under extremes of pressure and temperature. Facilitates slip between sliding metal surfaces. Highly corrosion resistant and non-gumming. Non-dieseling in air-rifles. Shake well before use.

Moly G-n Paste - I think we are all familiar with that too.

Curiously enough, the Silicone Gun Oil 35 and the SM-50 bottles are still full, I haven't used them! For leather washers I have used NeatsFoot Oil, and for metal to metal I have used the usual pastes and greases and oil.

Spot on. This was how it was done in the '80s, and SM50 was certainly marketed and labelled as a Silicone based lube.

Not just Bowkett, John Whiscombe also recommends using Abbey SM50 diluted with Abbey Silicone Oil () to lubricate the o-rigned piston heads on his springers... if you don't believe me check out the "Bulmer Does a Strip" article on Whiscombes.
