Hi
when i compare my stainless 3006 ruger's rifling to my other rifles. the rifling looks very shallow. i wonder what is good with that? i bought that rifle new not used and don't know why ruger made barrels with such a shallow rifiling?.i am afraid that barrel will wear out very fast
regards
yes

Trust me you will not wear out the rifling by shooting it... only by neglect.


We may just cut them shallower on this side of the ocean.

The typical difference between bore and groove diameters is .008" - .300" vs .308".
The Marlin Microgroove rifling has half the groove depth .They both work fine.

the problem is not only dept . the lands are very smal barely 1 mm in width, but groves are 3-4 times wider do i got a friday exemple or all rugers have the same rifling? any one checked their ruger's rifling?
regards
yes

Rugers are known for their durability. I think you are worried about nothing.

The Ruger barrels are all hammer forged so the land width is set by the mandrel profile. They can't vary the width of the lands or grooves.

you mean the width of land and grove should be the same? it is absolutly not in my ruger's case!!! anyone checked the new rugers barrel's inside to see if they have same kind of barrel?

yes

No.

Some Rugers had Micro-groove barrels.

mine have six large very widegrooves with very thin lands barely 1 mm wide. i have never seen a ruger like that before can't be called micro groove , maybe macro- groove i don't know if they have missed the quality control or all new rugers are like that?

My Ruger lott has earned the Shootaway AWARD OF EXCELLENCE in the rifle barrels category.

please answer to the question if you can!! and not many other argument.

I am trying to help in answering your question by using my Rugers model rifling as a reference towards long lasting rifling-be it the type you describe shallow or otherwise.What I don't understand in your post is that you seem to have come to some conclusion or opinion on shallow rifling before you bought the rifle but bought one anyway.

dear friend
i diden't saw the rifle before i received it. i diden't had the posibility . i ordered that and i only saw the picture. i have had rugers rifles before and their rifling don't look the same. the rifle is new model with better looking stock and trigger is great, what i want to know is if ruger has changed their rifling method or shape of rifling recent years or i have received a defected one,
best regards
yes

Dear YES,
Why not address this with Ruger either by email or snail-mail. Tell them your reservations and ask them if they will warranty the rifle IF the barrel goes south early in life or is very inaccurate? I have had decent results from them for many years although not having to use them that much. Heck! Won`t cost a lot and it could give you the peace of mind to give the rifle an objective try.
Aloha, Mark

have you tried to contact a company like ruger or whatever other company??.i don't know why it would be impossible to answer to my question!!! a watch inside the barrel of one of your new ruger to see if it is same as mine or not . woulden't take so much time.i want to be sure if i received a normal rifle or i have received a gun which been altered .i haven't bought it from ruger company it was bought from private person.

Yes,
You don't say what the depth of the rifling actually is so I assume it's normal (about .004"). A rifling configuration which feature narrow lands in relation to the grooves is not unusual. Some believe narrower lands are preferable since they distort the bullet jacket less. There is likely to be little difference in barrel life in practical terms.
As Fjold mentioned, the dimensions of a hammer forged barrel are established by the mandrel and it would be impossible to vary groove width.
Harry Pope produced barrels with very narrow lands and wide grooves. Both Winchester and Remington barrels have grooves roughly three times as wide as the lands. Shilen barrels, about the same. It is probably a good barrel and you should shoot it to elvaluate it's performance. Regards, Bill.

hi bill
thanks for your reply. i have shot this rifle and preliminary accuracy is not bad at all. many beleives the wider groove make it easier to clean and maybe it is new kind of rifling, but as i said it is very diferent from older ruger and winchester i owned before i don't know if it is a new model rifling adopted by ruger . i am living in remote area have no possiblity to go to gunshop and check if all the new rifles have same kind of rifling. why i asked this question.
regards
yes
