The Remington 700 ML 209 shot shell conversion kit we sell is very different from the original rifle's system, or any other 209 systems available for the 700 MLS. Our system uses a bolt nose that holds and feeds the primers into our unique breech plug. The action of the bolt swages the 209 primer into the breech plug; sealing it up, and essentially eliminating blow back. Thus it requires a little different maintenance than the original system. Most of that is due to our breech plug being of a different design: It uses a vent liner.
So people only familiar with the old system, do have a new component and some learning to do. But it's not hard; it is simple breech plug maintenance.
The instructions that come with the kit explain this, and it gets into more depth in our Frequently Asked Questions (FAQ). There is a lot of good reading in our FAQ but I wanted to emphasize it again here. Excerpted from the instructions that come with the kit:
Breech plug maintenance: After firing 209 primers, burnt priming compound will coat the flash chamber & the flash hole of the Vent Liner. To clean: remove the breech plug & ream the flash chamber gently with a just under size drill bit (7/32). Use torch tip cleaners to clean the vent liner. Scrub & remove all fouling with the appropriate solvents, & place anti seize on all breech plug/vent liner threads before using the breech plug. Eventually the vent liner will wear out; it should be replaced when it’s interior has opened to .036” or accuracy will suffer. Always use a vent liner in the breech plug, or you may see excessive/unsafe pressures at the primer!!!
None of this is new to anyone who has owned or used many of the newer designs that use 209's to seal up the breech. Here is an generic breech plug maintenance image from Blackhorn209.com:
The main difference between our breech plug and the generic one above it that ours uses a vent liner to form the flash hole. This is because each shot erodes away part of the flash hole, and if the flash hole was machined into the breech plug eventually the entire breech plug would require replacement. It's much better to only have to purchase an inexpensive common vent liner, over replacing an entire breech plug.
So that leaves the question: "When is it time to replace the vent liner?" The simple answer is when its interior has opened up to .036. Vent liners start at about .030 and open up oh so little with each shot. We sell .036 ZZ gauge pins to help you determine when its time to replace them. Alternatively when you use torch tip cleaners to clean the vent liner, you can measure the largest one that will pass through. When its .036 or larger, replace the vent liner. Or in other words, if the .036 ZZ pin gage passes through, replace the vent liner.
If you don't replace the vent liner when it opens to .036 you can expect a drop in accuracy. If you keep shooting you'll continue to open it up, accuracy will degrade, and back pressure will start deforming primers. You can read more about this in the FAQ (Frequently Asked Questions)
This time Jessica A, from Virginia wrote to us on FaceBook concerning the Remington 700ML/MLS 209 Shot Shell Primer Conversion I performed on her bolt. Check out her nice buck below!
Thanks a million! I had no worries about my gun firing this year. The Remington 700ml 209 conversion did the trick! Jessica A, Virginia
Jessica reached out to us a few months back via our contact form. She had a lot of good questions. I answered them via email and gave her my phone number. She called. During our chat she mentioned that she'd missed a few bucks due to miss fires and was ready for a better solution. She purchased our Remington 700ML kit with installation, and sent me her bolt. I converted it and sent it back with the breech plug and other accouterments. It's always great to have happy clients... most especially nice when they share that they bagged nice trophies! It's great to have clients that 'like us' on FaceBook. It really helps to build a business and we aim to please!
I'd like to interrupt my normal blogging about our Remington 700 ML 209 conversion kit and post this in remembrance of a classmate, Brian R. Hoke, USNA '96 (Who pummeled me in Plebe boxing, but still was my friend through graduation.):
A Virginia community is mourning the death of a former Navy SEAL.
Brian Hoke, 42, of Leesburg, Virginia, died in Afghanistan, his father confirmed.
No details were released about the cause of Hoke's death.
Hoke was a 1996 graduate of the United States Naval Academy. He went on to become a Navy SEAL. He left the military in 2002 and had worked for the U.S. State Department, with many overseas deployments.
Hoke's funeral was held Sunday [30 Oct 2016] at the Naval Academy. He is survived by his wife and three children.
American flags lined the streets of Hoke's neighborhood on Monday in his memory.
