ok before anyone says it... i know and agree that the more you spend on a scope the better ..... But ... i have a 0.270win for about 18 months now, payed €400 s/h the scope on it is a hawke 6.5-20x50 and while not really clear enough in low light was ok, it is now not holding zero, borrowing a scope of a friend confirmed this, just under 1" groups opend up to 6 - 8" and missing a 2ft target once! (at 100yrds) after chatting with other people on fb i decided a vortex viper sounded very good value for money and here is my problem, due to other comitments i cant afford one this year ( car has just died and house needs repairs ) so i'm thinking ( and feeling very uncertain about it) of getting a cheap scope to do for a while and when i can afford it get a vortex and put the cheap scope on my HMR which has a 3-9x50 hawke which is ok but i find bunny headshots over 130yrds hard ( maybe own eyesight to blame! ) so i'm thinking of something like nikko stirling nighteater or targetmaster, MTC viper or Barska euro30, budget will be about £200 (car first! ) what i'd like to know is has anyone used any of these scopes on centerfire rifles in low light conditions out to 3-400yrds and what do they think?
