Use all your normal equipment; including the sling; a scope sight and a couple of sandbags or a small rest to support the left hand. You should soon get a pretty good idea of which ammunition performs better and you will probably learn something about your own shooting as well.

Sandbags are the traditional favorite. Not expensive and work well if you know how to use them.

I have a front rest and for the rear, a cut-off jean leg filled with beans.

It is routine that shooters on either side of me have fullbore rifles, on a bench, a few feet above my head. This is why my range has a strictly enforced rule that all muzzles must be forward of the firing line, and all body parts must be behind the same line. We also have Range Safety Officers (RSOs) watching the line to make sure no one gets frisky and starts handling weapons in unsafe directions. My suggestion would be to tuck yourself to one end of the line or the other if you can, and pay extra attention to where you're pointing your muzzle. Honestly, once you get it set up on the bench it should be fine, since you're not going to be moving your rifle much at all. If it is an issue, you can always setup your rifle and rest (whatever you decide on) on the ground instead of a bench; depending on how stable the benches are at your range, the ground may be the better, more stable option!

As for a setup for testing, I would skip the (cheap) plastic MTM rest
altogether. In my experience they move far too much to be effective for ammo testing. Sandbags are great: cheap, and able to be homemade if you don't have some handy to start with. If you are going to buy a rest, get one with some weight to it. I use a Caldwell Rock. It works well and wasn't expensive.

Here is a little known tip - regular toilet bowl mounting bolts fit into an accessory rail (Anschutz) just perfectly. So I bought a 1.5 x 1.5 piece of hardwood, drilled three holes for the bolts, mounted that in the accessory rail, and locked that into the vice. Presto! A solid machine rest.

Given that, I got the same results with the machine rest as I did shooting from the bench, the shoulder, and from the shoulder with a rest under my sling arm. At least in terms of which batch I was testing was the best. The machine rest gave slightly tighter groups.

I tested from a bench with a Caldwell rest and rear rabbit ear bag. I used a 24x Weaver T-24.

It gave me a fair comparison. I selected the ammos that did the best and shot from position with the scope. Finally, I tested from position with the irons. The scope and irons both matched or beat the groups from the rest for the shots called good.

I absolutely believe that you can test ammos from position as well as from the bench.

Also, don't underestimate some of the lesser expensive ammos. I have seen multiple times where the best groups in a rifle would come from the
least expensive from a brand and the most expensive from a brand with the midrange products being poorer performers.
