Sighting In a Marlin 336 .30-30
I have found some ammunition that groups well in my rifle, but I can't get the windage adjusted just right. I am attempting to drift the barrel-mounted rear sight enough to move the point of impact 2" at 50 yards. The smallest adjustment I have managed so far moves the group 4". This has left me in an ammo wasting wild goose chase of shooting a group 2" left, drifting the sight, shooting a group 2" right, drifting the sight, shooting a group 2" left, and on and on until I am out of ammo.
I have tried tapping the sight with all shapes and sizes of non-marring objects, but the group either moves 4" or not at all. Help.

Don't tap so hard!
Sorry. Were I having that problem, after I got done cussing, I'd scribe an index mark in the bluing of the sight and the barrel. The point of a very sharp knife will work. I'd tap what I thought was "good enough" and then shoot. The index mark allows going back halfway. When you're done, color the index mark with a black Pentel or use a Q-Tip with a dab of cold blue. |

Place a small piece of masking tape on the barrel next to sight. Mark the centerline with a pencil. Now you can tap the sight and observe how much it has moved.
Good shooting to you. Jack

A cheap Williams receiver sight for the rear will solve it all for you and make future adjustments a pc of cake. I put Williams peep sights an my friends 336, my 1895, my 10/22, and my sons R700.
Life is good now with peeps. Don't tap so hard, LOL! |

Don't they make a sight adjustment tool . It clamps or something on to the gun and uses a T-handled screw to push the sight over slowly.

Sights that are mounted directly in a barrel dovetail must be drifted, unless they have a screw adjustment built in. . |

Marlin shouldn't be putting step sights in their rifles...
1. Drift sights SUCK. 2. Marlin already makes something better & less expensive... $10 will solve Everyone's problem with imprecise drifting of sights... http://www.gunpartscorp.com/catalog/...180&catid=4082 Looks like this when installed...and is SCREW ADJUSTED!!!

Thanks for the tips, all.
I'll give it another go with a reference mark, and hopefully put a receiver-mounted sight on it at some point.

A Williams FP peep sight will give you micrometer accurate windage adjustment.

Sounds like the dovetail might be a tad oversized as well as have uneven surfaces. I would try a second rear sight, and when you get it sighted in try some sealant on the sight and dovetail. I have a Marlin 336, been there, done that.
I have been looking for a "universal" sight pusher for a while, really haven't found one, it seems they really have to be tailored to each firearm. Last edited by SIGSHR; October 25, 2012 at 04:23 PM. |
