I don't see a score, but it looks like a clean to me! Very nice.

Bart B. · October 29, 2014, 03:31 PM

The article in the link says it's score is 200-11X. The picture in the link shows 9 pasted holes in the ten inch 10-ring and 11 pasted holes in the five inch X ring. Group of 20 shot's about 8 inches. Very good for a daytime match.

Here's a plot of my .30-.338 Keele 1000-yard match rifle's test group with 15 shots of 190's and 15 shots of 200's fired alternately (to see what about 30 shots with each load might do). They were fired using an F-class position. All 30 shots measured inside 6.5 inches on paper. Each load's 15-shot group is under 5 inches. That X-ring's 10 inches diameter.

It was fired 19 years ago at about 6 AM when the air was dead calm.

In comparison, the 1000-yard any-sight (scope) record for normal slung up in prone position shooting any rifle is 200-19X. Nineteen shots inside the 10 inch X-ring and one about an inch out on one side in the 10-ring. Shot with a .300 Win Mag as I remember.

Bart, Seems a shame you didn't bet McMillan you could of made lot of money but more than likely he would of wanted to shoot in the wind. Too bad you never shot any records shooting F-Class.

Bart B. · October 29, 2014, 04:19 PM

old roper, I've never shot an F-class match. Never had a desire to because, like benchrest shooting, it requires little marksmanship skills to hold the rifle very still while getting a shot off aimed dead center on the target. It's mostly a rifle, reloading and wind doping game, very little's a marksmanship game.

Lots of people have tested their match rifles in various artifically supported prone positions for decades that eventually became standards for F-class. Their many-shot test groups were often in the same size range as mine.

Wanting to compare two receiver stiffness values in the verticle axis (Gale M.' vs me issue you keep harping about) by shooting the rifles they're part of in the wind? Please explain your reasoning. Why introduce an uncontrollable environmental variable to some usability feature that has nothing to do with the basic parts issue?

That's why the F targets are half the size of Highpower.
Steady rest, harder target.

Bart B. · October 30, 2014, 06:41 AM

Jim, right you are.

The on-target holding area with F-class positions is 1/10th or less the size of that of the conventional prone position. And F-class positions allow rifles 50% heavier than conventional ones be shot in virtual free recoil. They move much more repeatable in recoil while bullets are in the barrel. Bullets leave in a smaller departure cone.

Had a question. Found the answer.

What's the question? Answer, too. Some of us are interested.

darkgael · November 5, 2014, 05:11 AM

The question was about the sizes of F-class targets as compared to a 1000 yard Palma target. Just needed to google.
Also, some of what I wanted to know was supplied in the post just before my last one....we were apparently writing at the same time. I edited my post to what is there now.

Are the rest of the results up?
A friend went to the F-T/R there and I'd like to see how he did.
