Modify mauser front sight

[concretus]

Okay; my mauser ( 1912/61 steyr cal 7.62X51mm) has the sights set for 300 yds at it's lowest setting. It's about 12" high at 100yds. I want to get down to 100 yds. One of y'all sent me a link for the front sight blank from Brownell's. (thanks by the way) . So I got one. I thought it was rather thick (.077) so I had a machinist buddy of mine mill it down to .052. I'm going to do the shoot and file method to get it down to either a zero @ 100yds or about 1"-1.5" high at 100YDS. Now here's my question: If I get it down to 100yds, will the graduations on the rear sight work for 200, 300,and so on. Would it be recommended to have it set at a different zero in order for it to be in at the further distannces. I pretty much have a load worked up the groups in the moa range.
Has anyone atempted this and what kind of sucess dod you have? are there any thing to look for or be careful of during the process? Any information would be appreciated. 8)

Hi,

i`ve done the file down method and i can say that the graduation on my rifle didnt really work. For an example the 300m was perfect for 100m the 500m worked at 300m ( the shots hits only 5 cm lower) but no one of the others fits for any distance. I bought a higher front blade and it worked with the 400m at 100m and the 600m was perfect at 300m. I think the better solution is to buy an higher frontsight blade and leave the original one as it is.

So if I took the new, higher front sight blade, filed it down to be zero @ 100yds and the rear sight at it's lowest setting (the lowest setting is marked 3 for 300 I'm guessing), every notch up from ther will be like so: 3 on the rear sight= 100, 4 on the rear sight=200, 5 on the rear sight = 300 and so on. Does that sound right?

The problem you run into is the targeting philosophy of the military. A combat zero will not have a hit at exact point of aim. Example, one hundred meter sight used at 100 meters hit 12 inches high. Same sight used at 200 meters hits 10 inches high. Same sight used at 300 meters is now 6 inches high. The reasons for this are that most battle sights are regulated for a belt buckle hold on the enemy and give a probability of a fatal hit for that range out to 3 to 4 times that range. The hit would go from center chest to the guts with the same sight used from point black to several hundred meters. You are in effect attempting to make the battle sights work like targets sights. Very difficult to get this to happen and match up with the original scale.

I understand...

From my experiences not really. Because the steps between every adjusting notch are not equal and were made for the original ammo so that they will not completly fit also is a difference in the ammo ( More V° or lessV° ) will have influence on that too. There was no chance for me to use the backsight like you said. The higher frontblade will not compensate the differences in height for an example ( made with my Swiss G11) 300m are equal with 100m and 500m adjusting is equal with 300m at the range. At 400 metres the rearsight should have an notch between 600m and 700m so you can see that it will not fit. Sad but true.
