Central peep sight

[stevebc]

Calfed, I note that your Central has "7.62" just under the elevation scale, as does the one I inherited from my Dad. I was under the impression that this indicated it was set up for 7.62x51. (I know he used his on the 7.62x51 Grunig I also inherited). Is this true, and if so, would there be any issues using it on a .303?

BTW, unfortunately (or maybe fortunately) I also won a micrometer sight that was identified as an "original Svenson rearsight" with a mounting block on fleabay.

Anyone know anything about these babies? Can't find out much about these, except that they are described by some as the predecessor to the RPA sight. I think George Svenson was one of the founders of RPA Precision Rifles.

George Swenson was an American who worked for John Wilkes in London, a very colourful character who managed to get banned from Bisley for using a sight type that at the time was illegal (or actually not approved by council, although I believe the year after they accepted it!)
After his suspension he developed the rifle we know as the Swing and called the first model SIN 71, this was in effect sticking two fingers up at the NRA at Bisley by referring to the model as the Sin of 1971, the year they banned him.
Whilst at John Wilkes he invented a rear target sight which carried the Wilkes name and then later his own name. An older friend of mine owns Swing No.98, but thinks it was nearer No.35 as George liked to "up" his production to make it look that he was selling far more than he really was!
He went back to the states some years later and an ex buisness partner of his went to see him on hearing of his ill health, asked on his death bed if he had a message for anybody at Bisley he replied, bugger Bisley!

Just use it in the normal way!
obviously don't use the yardage scale because that will be out, I usually zero at 200 yards and then use the come ups for whatever the ammunition type gives me for the distances I'm shooting.

The only difference in sights marked .303 & 7.62mm will be the yardage scale. They will still give the same MoA (minute of angle) regardless of what ammunition they were designed for.

William Dunn, although not his first foray into sight making, the Central Sight patent 17801/34 was the most successful.
The original sight was available and in use prior to the patent date of 1934, but due to a long running patent infringement suite, it did not become commercially available until 1936.
The CENTRAL brand was to eventually overtake most of the sight manufacturers as the preferred option, diversifying into other related accurising components and continued thru three different models,(1,2,3 and finally 4) and several different Marks well into the year 2000.
It proved so popular, that it was illegally cloned in England, and replica brands were instigated when its patent finally ceased in the late 1970's.
It continues in use today, the TMAC sight is simply a robust copy of the original Central 4, serviceing and parts for these sights are readily available still.
Attachment 70342

and there are several mounting bracket styles to suit in styles for various makes of target rifle.

Sorry, a step backwards pleae Mr. William Dunn was an engineer at the SAF?

No, He was an Engineer in Victoria, the next state south.
His Father, William Dunn Snr. was also an engineer and ran a Bicycle Manufacturing Business in Kerang.

Thanks very kind

I used the central on my Omark years ago and had a T-Mac on my Neilsen with a 6 filter and with diffuser Gehmann that you needed an engineers degree to operate with all the bells and such on it but I preferred the Central one thing not that that there is anything wrong with a T-mac I had mine changed in to both 1/4 Ev and 1/4 Wind instead of the usual 1/2 E ~ 1/4 W.
Probably with the Centrals is to I guess is to ensure you have the correct range plates on them one for the SMLE and the other is for the 7.62mm.

Nice collection of sights Muffet.

My first TR, a Nielsen MN300, has a Central. Excellent sight. One thing to remember is that the calibrations on the sight plate are all very well, but the length of the sight radius will affect how much the group actually moves with each click.

Instead of using the caliber range plate guide you can use the Minutes guide on the opposite side and keep a record of minutes for different ranges as most modern day full bore shooters do.

Yep guess since I have only been shooting full bore since 1977 I would never have thought of that !!!!!!!!!! Thats why I run an excel spread sheet with 10+ rifles on the go for different types of shooting at the ranges/matches imagine how big my note pad would be having all the dope for all the ranges from 300~1000m and also on the 300yd ~ 800yd ranges we shoot on. I just find out what were shooting prior then open up the computer jot down the figures particular to the rifles to be used and away I go 1 small page to carry around, easy as. Yep and I run an external hard drive with the info and new input if I change a load in case the computer crashes which last week it did so I had to purchase a brand new computer
