Front Sight Height for 30-30 Handi- Rifle
« on: August 22, 2008, 02:06:30 PM »
I recently purchased a new 30-30 Handi-rifle. (NR receiver,SB2 frame). I have not fired it yet but it appears the factory front sight will probably be too short for the new Williams WGRS-H&R rear peep sight I have installed.  I would like to install a Williams Ramp and Firesight for the front. I will be using Remington 150 grain Core Lock 30-30 ammunition in the rifle. Is there anyone having the same rifle that has already determined the correct ramp height (Williams Shorty Ramp) and Fire Sight height to be installed in the ramp? Thanks in advance for any information.

I did the same thing on an OLD Topper that I ran across.  I used the info on the Williams web site to calculate the height for mine, it was within 2 in. of dead on at 50 yds. when I shot it for the first time.  Front height will vary according to barrel diameter, so you will have to run your own calculations.  The chart will get you where you need to be, though.

There's an online sight calculator link in the FAQs and help Peep and Firesights thread.

Daniel and Tim, thank you both for your responses.

I have tried at least two of the calculators and obtained a total front sight height of around .875". This is measuring with a ruler, then converting to a digital measurement. I don't have access to a caliper or micrometer. As I recall, a third, I don't remember which method I used, I came up with a total height of around .813". Both of these numbers appear to be a very high total height for this rifle in appearance, using a cut out to simulate the total ramp and sight height. I also called a sight company for a recommendation that I understood was a best guess (that I would not hold them to) based on a work up of another rifle that had been done there using 30-30 ammo of unknown bullet weight. This guesstimate was .656 total height. There is around a .225" difference between my estimate and the other one. This seems to me to be a significant difference. I understand shooting the rifle is the best thing but it is 65 miles to the nearest range for me. I am not looking for perfection on the front sight but correct enough to allow for appropriate adjusting by the rear sight when I go to the range. No vender is close that has firesights of the appropriate height without ordering so I would be ordering myself. Right now I am thinking about going with a 3/8" Williams Shorty Ramp with a .450" Ht, .250" W Firesight insert.  Would there be a significant difference in adjustibility or usability in going with a Williams .406" Firesight insert instead of the .450" insert in your opinions to make the front a little shorter to prevent snagging, bending etc? Any additional thoughts or opinions?

Thank you again for your interest

My 30-30 barrels are .660" and .680" at the front sight mount hole, the chamber swell is 1.1" in diameter, the WGRS is ~.460" high with the aperature mid ramp, using the Brownell's calculator, I get a front sight height requirement of .680" which would make a 3/8" shorty and a .290" firesight just about right.

Tim,

First let me say I purchased a Handi-Rifle based on the overall positive information at this site. Excellent site with loads of experience from people such as you. While I had visited the site before, I had not joined and as you know this is my first post. I am very much impressed with the quick responses and obvious expertise. I appreciate the opportunity to join.

That information was exactly what I was looking for. I think my mistake was to use a ruler and digital conversion vs. a more accurate micrometer (even though one of the calculators I used cautioned against this). Thus the .225 difference I referenced before. I don't think there would be a significant difference between your 30-30 barrels and mine. I'm going with the .680" total height you provided. That was exactly the information I needed.

Thank you again,

Drypowder

Mine is as near to .675 as I could make it.  I used a ramp off of a Remington of some kind, and a front sight that was out of the box of junk parts that my gunsmith buddy let me poke thru.   He robbed me though.  The base, the sight, and drilling and tapping two holes to mount it set me back $20.  Hiway robbery, I tell you!  Truthfully, the best money I've spent on gunsmithing lately.  It shoots much better than I can see.

Daniel,

Thanks for taking the time to provide the additional information. All information I have received tends to be in the ball park of .656-.680. RE: your gunsmith: Wouldn't it be nice for us all to be robbed like that occasionally. Good friend there. You'd be lucky to get away with a single drill and tap for 20 bucks here.

Hey drypowder!
Welcome! I'm a newbe too,  and having a ball! Every other forum I've gotton on has always been more trouble than it was worth. Not these guys. you'll find straight answers to your questions, and opinions that will have you writing back...alot!
I come here every morning, I really think it makes my morning coffee taste better! Mike
P.S. I'm going to use the same values on my .30-30 when I mount the FPTK.

Hi Mike,

 Thanks for the welcome. Great site here. Understand I am no expert, not even a relatively knowleable layman. But before you obtain a front sight for your rifle, I recommend you use the calculator referenced by Tim above, and use a caliper in measuring. Based on my experience as stated above "a ruler don't get it". I have no idea what the rear sight height of an FPTK is, but it may be different than the rear sight height referenced by Tim.  It may make a difference in your front sight height, but you won't know until you check it. Just my 2 cents. I can't wait to get my sight delivered, mount it on the rifle (hopefully with no problems) and get it to the range to shoot it.

I would have probably used the calculator to see if I was close. The last front sight I worked up was on a cut down trapdoor sporter, and it turned out to be a lesson in frustration.

Mike, the Williams FP-H&R-TK- is .375" high at lowest position as best as I can measure it, but a call to Williams would confirm it. ;)
