Suppressors antiseeze grease and cold weather

[corey4]

today was the second time i had the opportunity the shoot the can.

host: XDm 3.8 9mm with storm lake barrel
can: YHM cobra 9mm

the first time it was 45*, partly sunny and no wind. i ran about 100 rounds of AE 9mm and about 100 rounds of win .22 on my rem 597 rifle. no failures. later that day, my buddies wanted to check out the cans and wanted to see the guts. so i disassembled it to show them, and had a tough time getting the booster out. so i figured, while i had it apart, i would clean and lube it. and since i had a hard time getting to booster out, i figured i would "put a bit extra" on the booster assembly. i can't hurt, right?.....

today, it was 28*, windy, and snow.

the first 5 shoots jammed. the gun ejected the spent case, and did a double feed of the next round. i have NEVER had a jam in my 5 XDm's. of course, they didn't have a can. but, on the first day with the can, i had zero failures.

so my logic tells me that i put too much antiseeze grease on the booster assembly, and it was too cold and would not function properly due to thick grease. but after the first 5 shots, we didn't have a failure. we fired about 200 rounds.

i am thinking the first 5 rounds heated up the grease so it was less viscus and the grease being cold and thick was the reason for the failures.

has anyone else had this issue?

if so, is there an antiseeze grease that works well in cold temps and hot temps?

Re: antiseeze grease and cold weather

I recommend nickel high temp anti-seize paste for suppressor use. Some of the copper types will or could cause galvanic corrosion on aluminum parts where nickel won't. The other thing is that more is not better. Keep it reasonable. The grease base will gel or congeal in the cold and defeat part of the purpose. In most cans you don't need to use it on anything but the threads you don't want to seize up. In some cases it can just create more sticking of parts.....
you have enough carbon from the powder burning so adding more from the oil in the anti-seize won't help it will hinder.

Re: antiseeze grease and cold weather

umm, i definitely used way too much. oops.

would it be a bad idea to use WD-40 before i try to take the booster out for cleaning?

Re: antiseeze grease and cold weather

WD or any light oil shouldn't hurt when disassembling. It can help break down some of the solidified sludge. That makes it easier to get things apart. Many shooters use it as a coolant as well since its easy to apply and works for a few shots to quiet things down more. It does create a lot of smoke however so keep that in mind.

Re: antiseeze grease and cold weather

the reason i used so much antiseeze was because it was very hard to get the booster out, and i didn't want to damage the threads on the can. so i will give the WD-40 a try next time i disassemble.

thanks guys.
