Fully agree with first responent.
However, read ( or reread ) any books such as Boddingtons 'Shots at Big Game' or even Ultimate Sniper. If you have acquired/ mastered skill with a sling - don't lose it!
Not sure if you are going to target shoot or hunt ( both? ). The Harris will not 'fit' every occasion. It is very useful to maintain skill with various positions - look on a bipod as icing on the cake.
I have Harris bipods available on all stalking rifles - dependant upon terrain, perhaps use them for 60% of shots in the field. In the UK, after the telescopic sight, they are probably the single most important piece of hardware in terms of improving humane kills in the field.
Once sighted-in, I rarely use them on the range - because they are largely a known or given quantity. It's my flabby, wobbly body that needs practise as a gun mount!
