First off let me say I am pretty new to shooting a precision bolt action rifle, so if the answer to my question is out there or a simple one I apologize for asking.
I have a Remington SPS Tactical in .223. I have the scope leveled with the bore of the rifle, using the Wheeler Professional Reticle Leveling System. My problem now, or what I think is a problem, is that when the rifle is resting on the bipod (Harris BR model) it throws it off level. Is that gonna be a issue with my point of impact or am I over thinking this? Is there a shim out there that can be put between the bipod & the stock or do I need to make one, & out of what if so? Thanks for shedding any light on the subject. |

Part of your answer is in Block 4 of that topic. Assuming that you have a fixed, non adjustable bipod? If you do, you might just have to "muscle/hold" the rifle/scope level. Key to remember, mount the scope on the rifle, with the rifle and scope both level to the horizon. Then when you level out the rifle, you level out the scope, and everything is good. Best solution to the problem, make sure that you have a bipod that you can easily adjust the cant on. Harris "S / Swivel Series" - IMHO, best option for the money http://www.harrisbipods.com/HBRMS.html Just make sure you have a knob or level that allows you to adjust it quickly/easily http://www.harrisbipods.com/HB747.html http://t-nuts.com/index.php?cPath=48_51 Atlas - not as quick or easy to lock down, cost more money, but also has more features http://www.accu-shot.com/Atlas_Bipods.php Unless you are going to do all your shooting from permanent/improved positions, then you are going to need the adjustability to compensate for unlevel surfaces.

| The BR in your Harris BR model stands for bench rest. It is non swiveling and designed to be shot from a level bench. I'm sure you could use some thin material (not sure what exactly) to shim the bipod level with the gun. However, if you are going to shoot your gun prone from the ground than your problem is only going to compound since your bipod doesn't adjust for cant. You can only adjust for uneven ground so much using the adjustment in the legs and if you want to be exactly level than you'll need a new bipod like the Harris BRM-S or Atlas. |
| Check to make sure the little rubber strips are still in the "cradle" of the bipod. I've seen them come off then when you tighten the thumb nut it's off just a bit. As for shims on the bench, I've used empty primer trays. The CCI trays are thin while the Federal trays are thick. I've even glued some up for use under sand bags. |
| I have the same bipod and it is just not a precise tool. It throws every one of my rifles off level in the same direction when set on a level base. To compensate I loosen the nut and move it where I want. Just loosen a little bit and I can still apply forward pressure while turning the rifle level. |

Thanks for the replies everyone. I think I may have misunderstood the definition of swivel on the Harris bipods. I thought maybe it meant that it rotates left to right, to get on another target fast. Does it really mean to adjust for canting?

In terms of Harris,
"S" Models Swivel = Cant/Tilt Side to Side This is pretty much a must for shooting on anything but improved level surfaces. Pan = Movement Left & Right They have an adapter called a "Rotapod" for that movement: http://www.harrisbipods.com/RBA.html If you have to engage multiple targets over a wide range of space, then this can be very beneficial. Not that Harris is the only game in town, but since that is what you started with, that is what I have been basically sticking with. Best of Luck, M Richardson |

Yep, panning is the feature you were thinking of as the Captain said.
Swivel is floppy in the vertical axis; roll left or roll right. That lets you adjust for uneven ground. The older basic Harris bipods had a brass plate that you could shove left or right to adjust some for an uneven/crooked front sling stud. Look on the bottom, should have a brass plate with a couple scribe marks. Adjust and fit to rifle, and recheck. That'll be what you want to do for the bench. Once set leave it set that way. You'll almost certainly be adjusting for uneven ground with the bipod leg adjustments anyhow (assuming you're using the fixed model). Just shorten one leg to level and lock with the thumbscrew if that type. Not that big a deal but it takes time to do. Alternatively you, you adjust the dirt. In any case you don't want to shoot long range with the gun and scope not in vertical alignment. Even if the gun and scope are true but you hold it crooked, you'll be shooting wide to the low side and you will shoot lower. (you're swapping your vertical scope adjustment into the horizontal when you roll the gun over. ) That said it can be done with cant but you need to be always consistent and know your dope for it. IIRC G David Tubb does or did hold his match or service gun in a cant to fit his body but his scope was level (not square to the gun). Obviously he tested it and knew his dope. I read that in one of his books eons ago so I may have something a touch off. The rest of us lesser mortal probably just try to hold a level gun and level cross hair.
