I finally got the rifle last Friday, so far I have taken it to the range for some sighting and breaking in, but am yet to try it at long range (over 200m)
Sako stainless varminter, Nightforce NXS 3.5 - 15 x 56 and Harris bi pod, it's a little heavy but I am very happy all the same.

I did get to shoot a pig with it, and to say the least was AMAZED with what the evil little pill did to the poor piggy.
Only complaint is that the shot was at about 10meters and on the run.

Express what do you think of the Harris bi-pod. I've been thinking of getting one. Are they well made and sturdy? Don't they just clamp on a sling stud?

Well the bi pod was just hanging around after having been abandoned by my dad so I figured it would be a good addition to the rifle.
It does just clip over the sling stud and it is sturdy and well made, though quite heavy.
The legs on this particular model can be extended at two intervals but are too long at their minimum setting for shooting prone, unless you are to shoot uphill, but it is very good for shooting in a kneeling position.
The legs can however be regulated to compensated for uneven ground by a screw(with a serrated disc for a handle) that blocks them before they reach their full extention.

I don't like the rigidity of it, so if you need to change point of aim significantly you have to re-position it.
Comparing it to the only other bi pod I have - the built in job on the Steyer scout(which has a funky "roll" to it that give you some freedom of movement), it is rather unpractical, but then again so it the rifle it is mounted on.
With the rifle in a horizontal position, the base of the bi pod stands at 34cm centimeters high, while the one on the Scout stands you at 25cm, a better height for shooting prone, but useless for any other applicaiton.

The bi pod I have is most likely an old model, so maybe the newer ones are better.
I's say it's biggest limitations are weight, wich may have been overcome in the new models, the height,(if I recall correctly you can choose from different hieght models anyway) and the lack of any flexibility.
I saw a site that offered a bi pod that was mounted on some kind of ball bearing setup, looked good but I can't rememberthe name of it.

Hope that's of some help to you.

Thanks Express. That was a pretty full account of the thing. I'll ponder it's merits for my purposes. Mostly I was thinking of long range sitting shots. That's my favorite position when I'm "rock hunting."

Hi Express,
I also took delivery of a sako 75 varmint stainless 6PPC earlier this year. I was mistakedly supplied with a 1 in 14 inch twist barrel. This limits be to plat based 80 gr projies as a maximum. Have you checked your yet with heavier than 80gr? Eg, 85 gr BT projies or 75gr Barnes X; don't stabilise in mine.
I've developed loads with 58gr Vmax and BM2 and have got 0.25MOA at 200m (3 shot). I also get about 0.8MOA with Remington 80gr PSP. This round went Pig shooting in western NSW in March; did ok except on a rear end running shot. Not enough data though to draw conclusion.
I have a 1 in 12 inch barrel ordered through Beretta under warranty, however, timing-wise I'm not holding by breath.
What projectiles/powder have you used so far?

Lots and lots of options on the Harris bipod.

They have one with detents on the legs for various heights, and one with a smooth leg that allows adjustment and leveling without setting the leg at the detent.

Other options include a swivel base or a fixed base. The swivel allows leveling of the gun on the bipod. The fixed is more for shooting off benches and level surfaces (I suppose).

I got a Harris with my used Rem 700 PSS that used to belong to the state police. The mount on the sling stud will generate considerable torque. This bipod had been tightened to the point of pulling the sling stud out of the stock. The stud in the PSS is "bolted" into a flang in the kevlar, but pulled loose through the foam core interior.
