thx a lot to all for your recommendations
i wrote with Lee Shaver and and it will be no problem to send the sight by USPS.
(The same easy way i have had with Al from NOE Bullets)
As i wrote before i can only shoot at 100 m, very seldom 300 m .
Windage adjustment are needed to make for one time only, that all. ( most time)
My first look was at the Pedersoli USA 431 but it seems to be Clumsy in the lower part ( Windage Adjustment) so i have had a look at the USA 430 or 446 Creedmore Sight because it looks to be more slender .
I always need a Long Range hight because i have just a Roller and a lot of adjustment space from the sight are out of use by the lower tang opposide to a Sharps
I read that Lee Shaver use or has used Parts from Pedersoli back in time.
if it was the thruth i don`t know.
but if Lee use Parts of his own the Lee Shaver Eco Sight looks like nice as the much expensive Pedersoli Soule Sight not to talk about Heilman or Baldwin Sights.
to explain my behavior..
The Lee Shaver cost 225 USD plus Shipping round about 220 Euros
The Pedersoli 430 and 431 or 406 are 205 Euros plus 6 Euros shipping
The Soule Sight from Pedersoli are 340 Euros
MVA Soule up to 800 Euros
C- Sharps up to 900 Euros
