How to pick a reamer?
« on: February 28, 2011, 01:41:23 PM »
Ok, I got a deal on some 1x fired 445 SM brass and could not pass it up. I am looking for a 44 mag barrel to ream out. I know reamers are available to rent, but what kind of reamer do I ask for? As I understand it, the conversion is just like the 357 MAX and is right up my alley.

Also, I think I want a shorty forty four. Is 16.5 inches a good bet for accuracy?

Thanks y'all

For this type of job, I would get a cast of the rifling ahead of the chamber to measure. That is how you determine what pilot dia. you need on the reamer so it doesnt wobble as you deepen the chamber.
Some reamers have a replacable pilot, the less expensive ones are ground as a part of it. Either will do a fine job as long as the pilot is right, the flutes are sharp, use plenty of cutting lube and you dont abuse it.

I'm glad you found the brass....it's hard to come by these days.  When you buy a barrel, get a new one and not one of the older over bored.  It's a lot less problem.  My .445 is an older barrel and I have to scrounge around and find fatter bullets and then run the loads through the Factory Crimp Die so they chamber properly.

Cutting my .357 Maxie ti 16.5 inches didn't do anything to degrade accuracy.  Just a thought, why don't you send in your frame and have it fitted with a Talo barrel, then all you'd have to do is ream it.  It would be a little longer, but still a shortie.

Pete,

What kind of reamer was used on your conversion, a rough or a finish type? I thought about the TALO, but I am not sure about the wait.

Pete's 44mag barrel was rechambered to 445SM with the 4D reamer.  ;)

Just one word of advice. I recently rented the reamer for my .44. Had a gunsmith friend assist. We were cautious and careful but the company still STUCK me for a 40 dollar resharpening fee. Not much I could do about it but in future I sure would take good photo's upon receipt and again before sendign back for documentation purposes. I'm really happy with the conversion, but not too happy with 4d!!

I hadn't planned on posting about this but if I can save someone a potential headache.......

I've rented 5 or 6 reamers from 4D including the one I did Pete's barrel with, never a problem.  ???

I've no doubt you did. I can only relay what happened to me. I just could not figure out any damage to the reamer on one barrel which took all of about 10 mins at most. But I really had no option as I was not in position to dispute. Next time I will have good photo evidence. In any case, I'm not really making a big complaint as I am happy with the results, just unhappy that I had to pay $40 when I really couldn't see any damage and couldn't figure out how any happened. I guess I should have asked for proof that they actually sent it out for resharpening.

Running the reamer with insufficient lubrication would certainly dull it quick, was the work done by hand or in a lathe?

By Hand + plenty of tap magic.....but apparently not enough.

Guy doing has 20 years of smithing experience, reamed quite a few barrels and has never had a problem before. (or at least not that he would admit too) In any case, it's all water under the bridge now. Still glad I did it.

It may be that after -x- number of rentals they charge the fee, and it may be that had you explained you had only lengtheded a chamber by hand, etc. that you might have got a pass on it.
And it may be that it really should have been charged to the guy previous to you if it was that bad.
In fact, if you have not talked to them gentlemanly about this and given them a chance to 'adjust' the fee you might reconsider, then let us know.

I agree, I've talked with Fred several times, he seemed like a reasonable fella, he ordered the 460 reamer for me, took a few requests, but he finally bought one.
