rimfire... who pushes buttons? That seems like a very difficult set of problems to over come. To put the much force on a rod thin enough to fit in the barrel without it bending, canting the button and rubbing on the rifling and ..... seems much much harder to control than pulling. I guess if the pusher rod was a tight fit in the bore and maybe a different button geometry than "normal". I will be glad to hear the pro side of that process.
At Hart Rifle Barrels, we welcome both questions and input from our customers at all times! We will try to include the important stuff that we think everyone can benefit from here ........
.... What is button rifling?
Button rifling is a barrel making process, in which a carbide button is pushed through a rifle barrel under pressure to displace metal to make the twist in a barrel. We believe that this type of rifling method is superior to other methods as it maintains a more uniform twist rate and depth of groove. Once you have a good button every barrel is the same as the last. Other methods require many passes to make one barrel, making it more difficult to produce uniform results.
.... Should I flute my barrel?
Fluting allows you to use a larger diameter barrel with the same weight as a smaller barrel. The smallest barrel we will flute is .650 at the muzzle. We recommend that you allow us to flute your barrel, as fluting is done before the final lapping, thus allowing us to maintain our guaranteed specifications. We offer six flutes, eight flutes (minimum muzzle diameter of .870), interrupted fluting, and octagon.
"Fast is fine accurate is final"
This debate will never be settled because of different opinions
and experiences but there is an answer that should get an
"Amen" from most.
Simply put : The Quality of the barrel makes the difference
not the method used to make the rifling. any method not done
properly will not perform.
Ther is another method used to produce rifling called Hammer
Forging it is used on the ultimate long range rifles (navy 16'' guns
with an accurace of 50 feet at 18 Miles).
I have used all types of rifling and found with proper procedures
during manufacture and good smithing practice they will all perform
better than most people can shoot.
As to the issue of different grades of barrels! during manufacture
tolerances will vary so the barrel maker can reject or accept based
on there preference. And he can offer a barrel at a lower cost to
customers that are not as demanding as some of Us.
I ask Lilja why he buttoned instead of cut his rifling and his reply was
(If it was better I would) And I beleve him.
Lilja flutes his barrels and shillen does not. when I ask shillen why
not? he said I'm not setup to do it and don't warranty if done by
someone else because (If done improperly it will effect accuracy and
Lilja does his in house and has control of the process ,I am not setup
to flute so I would have Lilja do mine.
As far as delivery from lilja I have only ordered a few barrels from him
and he met the 8 to 10 week PROMISED delivery date .
Every manufacture will claim there product is the best and well they
should but it's really the gun smith and the end user that determines
Get the best barrel and gun smith (In your opinion) and the outcome
should be very good .
You've got to be joking, I've never learned so much! Let the dance continue!!
Jesus Christ the same yesterday, and to day, and for ever.
Our Lord Jesus said that as it was in the days of Noah and
also as it was in the days of Lot so it shall be in the days...
It's happening again!!! God sent to us His prophet, and His Word
to this generation and we once more are rejecting it as was prophesied!!! ---> As promised, God Sent His Prophet to us!
