manson crown reamer

And those on here that have never used this tool and/or seen a muzzle crown ruined will give you all the confidence you need. There is a real big difference between a chambering reamer cutting a chamber and this tool that is NOT being taken into account here...the reamer and barrel have been dialed {should have been anyway} up to be in perfect alignment BEFORE the cutting/turning begins. Having this ridiculous little tool chucked up in a drill motor that you try but cannot hold in any kind of alignment while spinning in the bore is just not at all the same and cannot be compared. I would further tell you that even if you have the piloted version, that pilot is still about 12 times harder than the bore. You certainly wouldn't consider cleaning the bore with a cleaning rod made out of tool steel, why consider putting this thing in the bore either???
People buy these tools and either cannot shoot good enough to see the damage they caused or don't want to admit they messed up and blew the money...so they will recommend that you do the same. Do as you wish...I hope it works out for you, but I would not be too quick to run on back to that borescope after you cut the crown with a piloted {dead or live} tool!!! You are in for a disappointment.

"Been making them for 15 years"??? That's because they have been selling them to unsuspecting people {of which there is no shortage} for as long as they will buy. Simple business, but that don't make it effective for you. The old rule "if it sounds to good to be true...it usually is!!!!" A hand turned $50.00 tool is going to replace and do as good a job as a $10,000 lathe??? Right...one only has to look at the other end of the barrel for your answer. Ask these educated and experienced "gunsmiths" how many chambers they cut by hand with a drill motor while the barrel is chucked up in a bench vise!!!


These tools work fine, used correctly the produce an excellent crown, I had a crown checked that was done with the Manson crown tool by a nationally known rimfire benchrest gunsmith and he said it was perfect, he checked the bore with a scope and said he seen no damage from the tool and was really impressed with the crown it produced. I think if the tool was bad as it being claimed here you would be hearing about on all the forums. Go to some of the benchrest forums and do a search on this tool, these guys know what works and what dont and you will see the tool is fine
 
Weighing late on this issue of the use of non lathe cut crown, I agree with those who believe it is a bad idea. One can not hold a constant pressure on the cutting tool with out causing some chatter cutting the new crown. I used to work in machine shops for a number of years prior to working for a AR 15/ AR 10 company, (which I prefer not to name) and I would perform the finish lath work to Krieger S.S. barrels rifled barrel blanks for the AR 10's they sold. When I cut the barrels crown, I would support the barrels muzzle end in a steady rest, and used a slightly tighter then slip fit gage pin lubed with a high pressure engine assembly grease to index the barrels bore, than remove the gage pin to cut the crown whether it was cut with a square recessed or 30 degree crown.

Trying to cut stain steel with a hand held crowning tool will cause chatter do to the stainless steel be harder to cut do to the higher chromium content then say 4140 or 4150 which is more free machining. The milder steel used for 22 LR I have seen good results with hand held crowning tools, but keeping a constant cutting pressure is still some what of an art form at least to me.
 
He {the OP} last posted about this in March of 2016....that was before he bought the tool. Last post indicated that he is going to fall for it and has thus caught a good dose of what I refer to as "circus syndrome". Ever go to a big tent circus and pay the extra money to see some stupid, completely impossible, reality defying thing????....only to go in and realize that what they said is not what it really is, and that you just gave some hard earned money away??? Watch all the folks go in and as they come out they have this semi disgusted look on their face, but will not dare say to anyone waiting in line, "dude, don't waste your money"....{like I just did, because I would be admitting I was stupid, I'd rather have you be stupid with me...then I wont feel so bad}????
Colt Python's, Co-Ax presses, hand job muzzle tool.....circus syndrome!!!!!!

Sometimes standing all alone, jumping up and down, flailing your arms, telling people how stupid they are cause them to ignore you.

And yet your post is proof that the truth cannot be ignored...no matter how hard you try. Me {or anyone else} telling people they are stupid doesn't make it so...but, we cannot change the truth. The truth is that sticking hardened heat treated metal in the muzzle of a barrel cannot do it any good, period, end of story.
Most reasonable people and every benchrest competitor alive wont even clean a bore from the muzzle end in fear of "touching" the rifling with a plastic coated cleaning rod and you guys are telling people that it's not going to hurt to shove a heat treated hardened steel tool in it, while chattering around with a hand job drill motor???? Okay. Again, buy the tool, marry it... since you are so in love with it, worship the cat that made it like a god and please do not hesitate further to gunch up every rifle you own. Op asked for advice or thoughts on this tool and I have zero trouble getting to the point. If you cant handle opinions different than your own then it's yours to get over, or not. "Ignore" me??? what else is there after they've already bought the junk???

Read above .......... I have seen positive results from the Manson tool as I have done several crowns with them, never seen the tool decrease accuracy but I have seen it improve accuracy. You can be assured if it was bad I would say it here and the gunsmith I had to check the crown after I did it with the Manson tool was shocked how good the crown was and he did check it with a indicator.

I"m thinking you may have used one of these crowning tools and not had perfect results, or you are a conspiracy theorist that believes that every single person who ever used one of these is keeping it to themselves because they don't want to be the only one to waste their money. Since you obviously don't have a clue how they work, I am going to guess the second.

I"m sure the OP has fixed his rifle one way or another by now, but for the next round of people who need this information, if you take your time and follow the instructions, a hand crowning tool produces excellent results.

Buddy if after reading any of my posts you are somehow still able to think I would ruin one of my barrels with this thing then you are stupider than the rest of them. Me try one??? Less than zero chance. You on the other hand are welcome to gunch up every barrel you own. Let me say it again, I, like every benchrest shooter alive wont even stick a cleaning rod in the muzzle let alone a piece of tight fitting, spinning, hardened, heat treated steel.
Even if I didn't own a lathe or know someone that did I still would not waste my time with this thing.
