While we're aware of "bad press" associated with the use of cleaners with ammonia as part of the solution, we have never seen any damage in one of our barrels caused by the use of ammonia. The rumor is that copper-removing cleaners with ammonia will pit and damage the interior surface of a barrel. Ammonia is very effective as a copper remover. We use solvents, such as Butch's Bore Shine, to remove copper during the break-in. We routinely leave Butch's solution in the barrel over night too.

Rifle barrels wear mainly in two areas ? the chamber throat area and the crown. The throat erodes due to the high temperature flame from the burning powder and the swaging of the bullet into the rifling grooves. Crowns are usually damaged during cleaning. Refurbished barrels have at least 1 inch cut off from the chamber area, and the chambers are extended using piloted reamers in a floating holder. Threads are extended or cut on a lathe with a single point threading tool. See similar questions...

Though oak barrels are the traditional way Europeans made wine, we here at Wine the Experience opt to use glass barrels due to sanitary reasons. This however, does not mean we do not possess the capacity to create the oakey flavor distinctive to many popular wines. We add oak chips to certain kinds of wines during the different stages of fermentation to ensure an authentic and delicious taste. We use both French and American Oak, either with a medium toast or without. See similar questions...

There are some who swap barrels just by lining up witness marks on the barrels with a mark on the receiver. When we tried this we had problems. (Which is why we started playing with lathes and Remington "take off" barrels.) It was very frustrating to go to the range only to find that the neck sized reloads wouldn't chamber, or a shot at the hunter benchrest sighter hit one of the record targets after a barrel change.

The main barrels that I use are Hart, Lilja, Shilen, Broughton and Kreiger. I use them all on my own personal benchrest rifles and have no preference of one over the other. They are all good, top grade barrel makers and make excellent barrels. For the most part, I know the people at these companies and tend to use their barrels. See similar questions...

Ammonia is a metabolic by product from fish. Fish excrete ammonia from their gills and with their faeces. When faecal matter breaks down more ammonia is released. Ammonia is formed when proteins and amino acids are metabolised and therefore if fish are overfed, the left over food increases the ammonia concentration in the water. Another source of ammonia is the decomposition of waste matter (dead plants, fish, snails etc.). See similar questions...

Almost all of our barrels have a bandsaw cut one inch from the muzzle end of the barrel. This indicates that the barrel is not useable beyond that point. When we hand lap our barrels, we do so from each end of the barrel. Because the lapping compound is applied to the lap directly next to the ends, the bore becomes worn slightly oversize. This oversize condition does not extend more than .50"-. See similar questions...

We are asked if barrels can be sent directly to individuals or if they must be sent to a Federal Firearms Licensee. Rifle barrels can be purchased by individuals and sent directly to the buyer. There are no federal laws that prevent this. Rifle barrels are no different than other gun components such as scopes or stocks. The only restricted part of a firearm is the receiver. Further, if you already own a receiver you can send it directly to a gunsmith in any state to have it rebarreled. See similar questions...

Bring no more than two rifles into South Africa. The rifle that you use for hunting any deer species and other large game will work very well here. We recommend a flat shooting caliber between a .270 Win. and a .375 H&H magnum. The calibers in this range are frequently used with great success. Additionally, you can rent one of our rifles, if you would like. We have available high quality bolt action rifles in .308; 30-06 and .375 H&H magnum. See similar questions...

Rifles are prohibited in Illinois. The use of a shotgun slug or muzzleloader is permitted. A hunter can use either or. For further information and rules please contact the Illinois Dept of Natural Resources website. See similar questions...

That depends entirely upon your skill, knowledge, and patience. The average assembly time for someone with previous experience is 15 to 30 hours (excluding any art-work and finishing time.) See similar questions...

The check up in our premises (or outside of Germany at the Blaser service workshop) should be implemented within a few days. See similar questions...

We are quoting delivery times of about 4 months for rifles with unfinished stocks. Add two months or more if we are finishing the stock or the configuration is particularly unusual. See similar questions...

We are shipping all XCR? rifles with a Five-Setting, Quick Adjust Gas System. No tools are needed other than the tip of a cartridge. There's even a setting specifically for the use of sound suppressors. See similar questions...

The most common cause of excessive back pressure is due to the accumulation of particulates and permanently adsorbed materials at the top of the HPLC Column. This could be precipitate or un-dissolved particles which can come from your samples or your mobile phase. The best way to minimize accumulation on your column is to filter your samples, solvents and buffers with a .45µm or a 0.2µm syringe filter or through a filter flask before use. This should give you more column lifetime. See similar questions...

Axil can supply a full range of cleaning solvents designed to specifically remove our products. However, chlorinated solvents can be used to remove anaerobic and cyanoacrylate adhesives. See similar questions...

This is a usually based on cleaning frequency. In some cases, you may want to reference the firearms manual for their recommendations. For most users, we find the Phosphor Bronze Brush to be preferred. It is rigid enough to lift fouling from the grooves in the rifling, but softer than the bore so it doesn't scratch. If you're an occasional shooter, nylon is a good choice. See similar questions...

You should use a drill! Drill press has better accuracy. A hand held drill will work, but you have to remember to use a vise or other clamping device to hold the material to be drilled. See similar questions...
