Typically CVA’s, TC’s, and other models that don’t come with vent liners shoot OK until their flash hole enlarges… then accuracy will suffer.   Same sort of thing happens with Knights that have vent liners glued or brazed in.

Also the handful of the first Savage 10ML’s use a different vent liner than the much more prolific Savage 10ML2 (we sell the ML2 style vent liner).

To get back to those tighter groups one has basically two choices: buy a new breech plug, or convert it to take a commonly found removable vent liner, like the vent-liner we sell.   In the long run it is usually cheaper to convert the breech plug to take inexpensive vent liners.  In some cases (like for the short lived Savage 10ML) you can’t really get a replacement breech plug nor vent liners, so a vent liner retrofit is pretty much the only option.

Purchase this service,  send us your breech plug, and we’ll adapt it to take a vent-liner (aka “Savage Type” vent liner).    We will return the modified breech plug with one  vent linera hex L wrench.    Canadian’s will have to purchase the extra shipping to Canada (our bargain shipping is for US only: shipping fees are handled automatically at online check out).

Converting to use vent liners sometimes helps guns that were having trouble with igniting Blackhorn209 or blowing up 209 primers.    Contact us for the details.

Must be the type of breech plug that has a small flash hole that is small enough to be bored out and threaded 10-32 and that channel must be long enough to take a vent liner..
— or —
already threaded 10-32 (like the original Savage 10ML, and some Knights with vent liners brazed/glued in).  Also if you have a vent liner corroded in, we can drill it out and freshen the threads.  Basically if there is enough metal there to counter sink and drill & tap it to 10-32 for a vent liner we can help!If in doubt, contact us and we’ll work through it with you.

Savage 10ML vs 10ML2 vent linerThe original Savage 10ML took a different type of vent liner than the 10ML2. The original can be modified to take the 10ML2’s vent liner, but once modified it won’t use the original style any longer.

The very first Savage 10 muzzle loader wasn’t around for long before it was replaced by the Savage 10ML2.    Because of this folks with the very first model are having problems finding spare parts.   We sell primers modules and by modifying the breech plug to take 10ML2 vent liners we take care of the other part that wears: the vent liner.   Take a look at the picture to see the difference.   If you purchase our vent liner retro fit service, and send us your original Savage 10 ML breech plug we will modify it to take the 10ML2 style vent liner (and send it back with a vent liner and wrench)

Savage 10 ML breech plug retrofit to use ML2 Vent liner

This breech plug came to us with an original Savage 10 ML style vent liner corroded solid into it. It now uses ML2 styles without issue

​If you get this service I’d encourage you to buy some extra vent liners, and a gage pin to know when your vent liner has worn out.  Vent liners start with a hole that measures ~.030″ and should be replaced when they enlarge to .036.

Accuracy will degrade once the vent liner has opened up, so have replacements on hand and a way to measure the orifice.

Be-careful of others offering to perform this service!   I’ve seen bad work done that has caused heads to separate off of vent liners!  The depth of thread and counter sink angle must be set correctly, and a standard center drill, and common drill points are not the correct angle!

Turn around on this service can be as long as 4-8 weeks.  I hunt too, so it really depends on when you get your work to me, and how much I’ve got infront of me.
