hi l live in turkey and licence for a rifle costs around 3000 dolars here for 5 years and l have reached the end of my licience. l have 2 make a decicion of keeping my 7mm REM MAG heym sr-30 or sell it and buy a new one for my next 5 years of hunting. so l have a few questions... 1- the heyn rifle l have has a quality heavy barrel on it but l am not shure about how many rounds l have put through it. but think its around 900-1500 rounds. it shoots verry accurate at the moment with no trouble of knocking down ibex from 500 meters. so will l loose a big deal of accuracy during some period of time by putting another 900 to a 1000 rounds through it? 2- there is not many choces of rifles over here so if l sell my rifle l will have to buy a 30-06 8x57 or a 308 as there are no magnums on the market at the minute. and l hunt ibex so my shooting is made at 300 to 600 meters so not shure how l would do with a 30-06 or a 308 at longer ranges like 600 meters? 3- should l change my gun. ( when l look through the barrel l can see the rifeling clearly like the first day l bought the gun but the end end of the rifleing looks verry faint) it was allways like that though? is that normal? need help. what would you do? ...choices are mauser m03 heym sr21. dont forget lm gonna sell a heym sr30 straight pull. that is verry accurate less then 0.50 moa at 100 yrds.
