I’m in the market for new bore guides. The more I looked the more confused I became. I searched catalogs and the Internet. Brownells, Midway, Cheaper Than Dirt, Dillon’s, ect ect… Came up with lots of companies that make them. Dewey, MTM, EJS, Bore Tech Inc, Stoney Point Productions Inc, even Midway has their own version. Some are plastic some are aluminum, some machined metal. Prices from $11 to $50.
Do they all work well? Even plastic?
Some have a solvent port. Is that good or just a gimmick?
Will the same guide work for a 223 and 22-250? Some say yes some say no. Different chamber sizes.
Any help would be appreciated. Or personal experiences also. Looking for 308, 223 & 22-250.
Thanks, Marc

Full Version: Good & Bad Bore Guides??
Basically comes down to personal preference. Most bore guides work on most calibers. If not, then they have a small, med, and large caliber type. You would probably need a small for the .223 and a med for the .308.
Bore guides are a very good item. Having a lube port is nice too. I use mine often, but not all the time.
If you can wait a little longer, I just sent Terry of KMW an email asking about his. He designed a new one, but I'm not sure if it's hit the market yet or not.

Bore guides come in lots of different makes and configurations as Snip1er said. One of the most critical components of a good rod guide is how much it protects not only the bore of the gun, but the chamber and the bedding components.
Many rifles that are glass bedded using the older Acraglass or Bisonite, and these compounds are susceptible to damage from some of the solvents used, particularly copper solvents.
To protect your chamber and bedding compounds, find a rod guide that uses an O-ring sealer to seal off the barrel from the chamber and thereby the glass bedding. This also prevents solvents from running back into the action of the gun and maybe onto an expensive painted finish.

Here is a link to Sinclair International. They have benchrest components that are of the highest quality. Benchrest shooters strive to be able to clean their guns as efficiently and fast as possible because of the nature of their competition. They also have some very beautiful and expensive finishes on these guns.
A solvent port is a nice thing, it's usable, but an O-ring seal is more critical. The rod type guides (hollow aluminum shaft) with a major diameter guide in the front and at the rear of the action is personally my favorite. But again, the O-ring is critical.
One of the methods of cleaning a heavy copper buildup is to fill the barrel with copper solvent AFTER the carbon is removed. I recommend that you leave the solution set for 5 or more minutes then dump out the extra solvent. The remaining solvent will "goo up" on the copper streaking. This attacks the copper more efficiently and air is needed to make the chemical reaction work. That is why you need to dump the extra solvent.
Sinclair also makes a chamber plug with an O-ring that is used specifically for this purpose. Once the solvent has set a sufficient time, you pour out any "pourable" solvent, replace the plug with an O-ring type bore guide and punch out the "slug" of solvent, that is probably now very blue.
This got long winded, sorry, but it explains the need for a O-ring sealer.

Here is the reply from Terry at KMW on their bore guides...
**********************
I am having the first run of 100 guides produced (they say) in about 2-4
weeks. The initial run will be to see if they can run the profiles and
tolerances in as few steps as possible. That will then give them more
accurate information for $ costs. If they come out like I want, I will send
you a couple to use and critique.
...Only reason I did this was because I didn't like the Stoney Points, Deweys,
MidWays, etc. So yes, I am getting there and will advise as soon as
available. Thanks for the interest.

We really like everything else KMW has put out, so watch for their bore guides around the first of the year...Thomas
