Q:

Chamber reamer

Guys
As much as I have read so far, (and still reading more posts),
I have found NO discussion on a barrel reamer made to fit the pellets etc.

Yes, I realize that there are many calibers, sizes and shapes etc.

My background is from powder burners,
where if you want the best possible accuracy,
you have the best bbl is possible, LW bbl?,
with the proper twist for design and weight of the pellet,
a good chamber design for the case, ie: pellet shape/design etc,
uniform PSI = air pressure as possible,
among all the other specific items for AR shooting.

Wouldn’t the same spec’s apply to AR’s?

Mainly a good designed chamber for whatever pellet,
you find that has good accuracy etc, to start with etc.

Has anyone traveled along this path???

Any thoughts, suggestions or Ideas?

Tia,
Don

If i understand correctly you are seeking something similiar to a chamber reamer. However our airguns do not use or have usefulness for a chamber of any sort. My understanding is that the chamber reamer is to cut the proper amount of “headspace” as to how far the cartridge will seat within the rifle chamber. Airguns on the other hand require a small bit of “lead-in” or a nice concentric and consistient throated gentle taper for the projectile to evenly engage the barrel rifling. Airgun Lead In is somewhat similiar in cause and effect as the crown on the business end of the barrel. With firearms somewhat similar in terms of affecting accuracy is what may be referred to as “freebore” which is mostly the relationship of the bullet seating depth within a metallic cartridge case and the tolerance between the seated bullet of a chambered round and its distance to the start of the barrel rifling. This is usually also were a barrel is likely to go bad or shot out . The throat erodes and the barrel becomes less steller accuracy. 30-06 or 22-250 barrels suffer from erosion worser than many others. Tack drivers become shot out however its not the barrel per se but actually the chamber!
Lead in on air rifles is important but not nearly as critical with diablo style pellets that sport a skirted base. It is uber critical when using slugs with air rifles. Cratex Abrasive rubber mandrels are very good for use while handfitting the ogive of the projectile of choice to the Lead In of the airgun barrel.
I dont believe a proper chamber reamer for gunsmithing is going to actually do the fine fitting or proper cut that it is being tasked to do.
Please anyone correct me or point out if I my understanding or explaination is wrong. Maybe I am getting too technical but I really dont believe a chamber reamer like those used for firearms is the tool for such task.

Yeah I need to call him too for a .308 as long as he can make them!

Thanks Rick

That’s why I could not find any site info.
I’ll call him.

That will be the same path I am going to use,
once I have the Condor in hand and use it enough to figure out the best pellets for accuracy etc.

I have a very good company that grinds my custom CF rifle/pistol reamers, to any spec’s you want etc.

What I am really wanting, is to find a AR bbl company that has more/different twist rates,
instead of the standard 1×16-7″ twists, I want to test faster twists for the heavier pellet weights etc,
so far NO luck finding any info.

Lots of air gun smiths use ground down CF reamers. That is what I will be using is a .308 throat reamer when I make my hunting rifle from an AF extrusion.
