Procedure for Assessing the Accuracy of Rifles

The truth testing protocol for rifles has varied among shooters, but among the sorts of activities that were shooting, not just during the time. That protocol has changed without a barrel cooling between shots to five shot groups. A buddy of mine allows the barrel and fires 3 shot groups. Another provides five minutes to the barrel and shoots five shot groups. A test’s writer report I read years ago fired five shots but quantified only the 3 holes that are nearest in the target for the record. As I said, it varies. I’ve my own procedure for assessing the accuracy of rifles.

What I’m saying is they’ve worked for decades for me, and I see no reason behind shifting. The Ammunition – When testing a brand new rifle, I nearly always begin by shooting factory ammo if it’s available. As a result of excellent match combinations of the 308 Winchester from Federal and Black Hills, I love it when there is to be analyzed a rifle chambered for that cartridge. The amount of Shots – The rifle determines the number of shots to be fired in every group. A custom Remington Model 700 is a great example. Compared to tested vintage Winchester 94 in 32 Particular.

Back when I was in 3 Gun competition, some phases required emptying several AR-15 magazines. Target distances ranged from fairly close to as far away as 300 yards, so when truth-testing a brand new gun or load, 10 and sometimes 20 shots per category was the norm. The Setup – irrespective of the kind of rifle or what it’ll Be used for, I start the program by shooting it on sandbags from a solid bench rest. The bench consists of a 4 inches thick slab of reinforced concrete placed on concrete block pillars. – as opposed to Placing the chronograph atop the bench, I put it on a feces beside the one I’m sitting on.

Doing so makes it convenient to read, and the bench top shields it out of muzzle blast. The rifle is supported in the back by either of two kinds of leather sandbags. I have a number of front rests and many styles of all sandbags for them as well. The forearms of rifle stocks vary greatly at shape and width, so a front bag matching a certain stock as tightly as possible encourages consistency of all hold and discourages canting of all the gun. My Sinclair International front rest is set up with fast switch tops holding bags of all various sizes and shapes.
