Bluestem,
I think that bipods are great tools for assisting in long shots. I hunt pigs, blacktails and coyotes and never do it without my bipod handy. It increases my range a couple hundred yards. The negatives of bipods are they tend to cause the user to use them as a "crutch." The user must not rely on the bipod to much because there are many times it can't be used, good field shooting positions should still be practiced on a regular basis. The other draw back to bipods are they make your rifle heavier but they don't throw everything off balance, in my opinion, the added weight on the front of the gun makes it easier to control. I have used Harris bipods in the past ant they are ok, better than nothing but I think you should take a hard look at a Versapod. They are better than Harris bipods for a bunch of reasons. One, they don't weigh as much. Secondly, there no springs that can get caught on brush and things. Next, they provide a steadier rest and allow for a smoother, more natural reqoil. The Versapod comes with mounts that stay on the gun so that you can slip the bipod on and off as quick of quicker than you could get your shooting sticks into position. Notice I said mounts, plural, Versapod gives you two mounts so that you can easily use you bipod on two guns without fussing with screws and pegs. I only use a bipod that is large enough for prone shooting because I never used the longer ones very much, the situations were far and few between, not enough to justify the use of long sticks. Lastly the extending legs of the versapod can be extended with one hand quickley unlike the Harris. It might sound like it, but I am not a sales guy for versapod, I just hear everyone talk about Harris bipods and they are not the best things on the market by a far stretch. It would be nice to check them both out like I have so that you can make the best choice for yourself. Good luck.
