What does everybody use as support for testing group size? I have been using bipod and bag in the rear. Just seeing what others use.

I use a big bag in the front and a small bunny ear bag for the rear.

I always recommend the most stable rest you can use. In a perfect world it would be a solid(not $30 plastic rest) front benchrest and at minimum a rear rabbit ear filled with heavy sand on top of a rock solid bench.

After all, you are testing the ammunition/rifle combination and will want to remove the shooter from the equation as much as possible.

There's nothing wrong with using a bipod and rear bag just make sure you preload the bipod, use the same cheek pressure and follow through for every shot.

Bipod and rear bag. But that is a learned skill, that not everyone knows how to do.

Bottom line is, as with any type rifle shooting, is get still. As well as making sure the forearm isn't touching the barrel, whatever the front rest may be.

.

Some rifle stock combinations do not lend themselves to the bipod front as the front rest. I hear it said wood stocks are the worst for this but the "Tupperware" plastic/synthetic stocks found on lots of factory rifles are just as bad or worse for letting the barrel and forearm touch or even more pressure to be applied.

Right.I've figured out a way to combat that.

You need a piece of angle iron, 2"X4", square tubing, something solid ahead of the bipod feet, clamped or screwed down. Load the bipod very heavily, and many stocks will flex away from the barrel. I can make a Tikka, and Savage clear the barrel by an eighth inch or more, with the factory stock.

Is it good, bad or other wise to use a carpet mat on the bench top? In this case a heavy wooden bench.

Yes, that is loading the bipod. The harder the recoil of the cartridge, the more I load the bipod.

I feel like for me the bipod and rear bag are working best. I've tried using the sand bag in front but doesn't seem as stable. The benches at the range where I shoot have nothing to load the bipod against except a sand bag. Is loading the bipod more for controlling recoil jump or does it help you stabilize also. I tried loading against the sand bag but it seems to want push away. My recoil is not that big of a deal, I'm shooting a ruger precision rifle in 243 win. I've just started loading for it, I've had a couple groups where all are touching in a circle, had some groups where some are touching stringing right to left. Most groups, I will have 4 rounds touching and then have 1 off a 1/4" or so, I was just wondering how much of that would be human error or load/gun error.

Loading is for control, as well as to combat recoil. But I do it prone, and the goal is to witness impact down range. In other words, I see the bullet I shot hit the target, or splash in the dirt. I can make a correction as needed. You can load the bipod on a bench, and it will help, but not as effectively as doing it prone.

The only time I shoot from a bench is three days of prairie dogs, and even then I have angle iron bolted to the end of the bench.

Jason taught me the technique for loading the bipod and it does help me steady the rifle. My back tends to hurt shooting prone so I have used a piece of angle iron clamped to a bench with the same positive results. Some of the shooting mats have pockets/slots to place the bipod feet allowing you to load it. Give it a try without ammo and see just how stable you can get.

That's a mass produced rifle, you're doing all the good! up

To get any tighter than that, typically means a cut rifled barrel, chambered by a Smith that is extremely picky. That's another $700
