This thread - right in the emotive sweet spot of the forum faithful it has already, even in its inevitable infancy, produced some cracking statements, which we (for entertainments sake) will come to.
To answer the OP: If you read between the lines, modern rifles with factory ammunition are inherently no less safe no matter which the hand - it is a matter of preference and attitude to risk. Personally, I would choose an action that suited the eye from which I was shooting, although remember it is possible to have actions configured to port the casing either way to prevent it coming across your face. You should consider the stock configuration carefully as this can impact the ability to get ones head in the correct place comfortably. This thread should if nothing else convince you that the massive won't come up with a compelling reason to change the way your mind is already settling - to your personal preference.
"It's like kicking a football with the wrong foot" - Morkai (how are you bud?) - I expect more from you..... while I understand the sentiment, football is not as far as I am aware a sided game - I'd hope most use both feet (although there are some teams who do make you wonder....)
"Why are all 303's RH" - chuff - I mean apart from the obvious churning them out by thousands for the majority to use - could you not have come up with a more current example? I mean I appreciate it's VE80 and all that..... you could have gone for the early SA80 and it's right eject making it harder to fire around RH corners in urban environments...... and continued to ignore the fact that servicemen are trained to fire from both shoulders to minimise body exposure......
"Left-handed people should shoot right-handed rifles as it makes it easier for them to cycle the bolt" - FFS really. If this is true, why is the market not flooded with LH rifles for all those RH people who practice what they preach. This is one bit of BS spouted at LH shooters when they ask whether they should compromise that should absolutely be confined to the same annals of history as those relating to no need for LH 303's....
"Left-handed or eyed all ways seems a bit sinister to me!!" - subtle... ha ha -
