Newbie: 300 Yard F-Class Score.

[Taildrag15X]

Taildrag15X, Thanks for the posting and link.

One question.... What is the target size?

b) NRA No. MR-63 - Reduction of the MR-1 target for use at 300 yards to simulate the 600 yard stage of the
National Match Course.
Aiming Black (inches)
X ring . . . . . . . . 2.85
10 ring . . . . . . . . 5.85
9 ring . . . . . . . . . 8.85
8 ring . . . . . . . . 11.85
7 ring . . . . . . . . 17.85


Ummmmm confused.... The other "approved" target is even bigger! Where do these numbers come from?

The target as I understood it, and use for my scoring is.....

DIAMETER
MOA INCHES@300 RING
0.5 1.571 X
1 3.141 10
2 6.282 9
3 9.42 8

You should reread the post, it says MR-63 PRIOR to the NRA take over and the SMALLER Target which is known as MR-63FC and is the Center that is used to cover the MR-63. You'll find the info on the F-Class Target Faces in the High Power rule Book under Section 22-F-Class, 4; 4.4 which states that the X-Ring is 1.42", 10-Ring is 2.85"....etc.

As far as prctice and load testing goes I usually ladder test at 100 yards with 10 rounds or so, when I find a happy spot I'll work up 15 of each, shooting them in a Match format, all at one Target in 15 mins. without sighters to see the real "group". This is proven method for me to use as I have a piece of paper from the NRA stating the I are a good shot on occasion.

Well, on at least one occasion.

Seriously, I follow a conceptually similar practice. I do all load development at 100 yards over a chronograph. After evaluating the data and sometimes shooting a second set, I shoot a series of 10-shot groups at 300 prone from rest or bipod (Open or F-T/R) to validate. This procedure has served me well, too. I have never seen a load that groups well at 100 with low ES/SD that does not shoot well at distance.

 

[Keith Glasscock]

Same here except I do everything at 300 if possible. Unfortunately, the local SWAT teams had the 300 yard range pinned down today and I had to do some development at 100. Fortunately, I was just working up a load for the 223. I'm going to use it at 300 and 600 for practice (with light bullets) in order to gain some wind reading skill. Changing from a load that drifts <4 MOA in a 10 mph crosswind to one that does 7+ is going to be challenging, but I've got to learn how to dope the wind if I want to win.

BTW, Mike, that 150/13X is going to be hard to beat. With the recent improvement in FTR scores, I figure we'll be seeing +6 like the F-open guys soon. You'll have to improve on that one....

Sleepygator,

I shoot it twice that day, in Match #1 and again in Match #3.....I tried to post the Results in PDF but it's to large.

Busdriver,

I was in understanding it already is beat, just not updated, there were posts I read stating a 150-15 in both Open and F/TR......not sure of were, who or with what, couldn't find it or I would of linked it.

I find shooting without sequential sighters and pits makes it mean more to me, lay down and shoot 15 for Record and see what they look like.

As far as me bettering it, I'll more than likely have to travel/move as per the last Club meeting they are giving no support to the Tournaments. The Club had the only Monthly NRA Registered/Approved Sanctioned High Power F-Class Tournaments in New England
since the NRA got involved in 2007. Now they are more invloved with Turkey Shoots that create twice the income, twice a month of the F-Class Tournaments as it is a favorite of the summer Campers.

 

[Steve Blair]

Just kidding, Mike. No slight intended. The record stands on its own, whether once or twice.

The reason I do load development at 100, other than seeing no difference in outcome, is that our ranges are often quite breezy with both vertical and the usual effects. Shooting at 100 minimizes the problem. I also shoot over BR-style wind flags (Rick Graham), attempting to stay ahead of the condition.

 

[Keith Glasscock]

I have seen rumors of records that never happened, so I would not hesitate to make an application for a record if I tied or bettered anything showing on the NRA web site... Especially Mike's record

That is, in my wildest dreams :

Expensive mistake.... fired some Federal Premium Gold Match 69gr Sierra BTHP at 300yds.

My last 30 with PRVI... Average distance to center 0.522 MOA.
Ammo change to Federal.... Average distance to center 0.271 MOA. *

* This star was added because I only shot a 9 shot group. These were just leftovers from my 100 yard experiments that showed no "significant" difference between the PRVI 69gr match and the Federal. ( at 100 yds Wolf 55 sucked, Herters 55 sucked, Black Hills 52 was good but too light I think, Hornady 55 was ok, PRVI and Federal 69 looked really good ...)

I know I will eventually need to go to loading my own, but did not expect 'that' big of difference this early on with the top 2 commercial loads that I have found.

I figured I had to suck worse than the ammo.... maybe not.

Maybe I can ask Santa for a few boxes to confirm.

Busdriver,
The National Records are summited by the Club that is sponsoring the Tournament, and there are many broken that will never make the books due to the way the Match Programs are written, or I should say not written correctly, or incorrect info or missing info on the appication. For awhile the NRA was way behind and had Record applications from the past 3 years (prior to May 2011) to catch up on, all this as it was the sole duty on 1 individual who had way to much to do and no time for Records. Now the National Record reporting is under control and is being held to the highest standard of reporting I have even seen in my 35 + years of competiting/running Tournaments. The "new" staffer has set up an online reporting form and goes above and norm of calling and emailing about any mistakes or questions on Record Applications. As of this past Oct. there were 16 National Records set at our local Club, over 12 Registered Matches, 12 in F-Open and 4 in F/TR, with most being processed within 45 days of mailing.

I at one time had a little thing with Federal going on when I shot High Power, they gave me stuff, ammo, brass etc....some of my best scores were shot with leftover from practice Gold Medal Match 69gr. & 77gr. factory ammo in reduced Target XTC and Prone. Cleaned the MR-63 with an 800-61X using my Savage 112BT and 77's in a non Sanctioned Match.

Good to hear that things are getting better at HQ. I spoke with Habu about it at the long range regional and he told me that he kept offering to volunteer to get it up to speed for them...

Best bet is to sign up for the FREE NRA Shooting Sports USA online magazine. In it they list by Discipline, National, Regional and Other (Approved/Registered) by State with contact info, there is also an Archive for back issues. I have found interest in some of the articles, this month they high light the unbroken 1,000 yard Service Rifle 71 shot string of Bulls eyes shot in 1921 by George Farr.

Just a comment from the Land of OZ.
I shoot "F Open" and the 300mt target X ring is 35mm{1 3/8"}
At 300yd it is 32mm{1 17/64"}
Here is a 10 shot 300mt target I shot last year in June with my Gary Eliseo built R-5.
This group is the first string that finished 119.14 out of a possible 120.20
Blew up on the last shot, second target and put one in the 5 ring.
The green dot is a sighting shot of which you are allowed two and you can except both, one or none.
The second sighter was in the X so I kept it and continued the string.
I hope now that Shane has the bug he will keep at it as we have some very competitive shooters that use a .223 with the Sierra 90gr Match Kings. {1:7 twist}
This was shot with 103gr domestically made projectiles that I Boron Nitride, CCI 450's and Varget {AR2208}
Have posted this load before on the forum so look for it if you think you might want to try it.... {:~)
Just before Christmas I managed another 119.10 at 600yds with this load and rifle.


This group is 1 3/4" and if the #8 went on top of #6 or inside it would have been 1 1/2"

This 600yd group of 60.6 is 5.2"
All targets are using Hex System electronic scoring targets...
Now apparently being sold in the USA too.
You get instant feed back from a small laptop set next to you so that you can see each shot and speeds up a match as the targets do not have to be pulled @ shot and scored.
