F T/R Competition MR 63c target vs F-Class scoring rings

[MLC]

The planets finally aligned properly and I was able to make it to local match Sunday.
It was not an F/TR but an any rifle any sight match at 300 yards using the MR 63c target.

I shot with a load that looked good at 100 but had yet to be chronographed or shot past 100. I decided several weeks ago to clean my bore and never got to foul it again so I started this match with bare steel.

I totally tripped coming out of the gate, my score card was marked relay 2 at the top.
When the first relay started I noticed that my shooting position was empty and asked if I was supposed to be shooting in relay 1.
That was indeed the case so I hustled to get set up.
The first COF was unlimited sighters then 20 for record in 25 minutes.
I only got 18 rounds off total before the cease fire so I started out with a 40 point handicap.
I did pretty well considering the stumble at the gate
which got me a 155-12x including spotters.
The next two were 200-15x and 200-14x.

But am curious how the 8 & 9 rings on the F/TR targets compare to the MR 63c target?
I'd like to know how the wide the 10's I shot on the larger target would've been scored.
Is the X ring on this target the same size as the 10 on F class targets?

I've only competed at 800/900/1000 (800/900/1000 all use the 1000yd target) so I may be wrong but I think that the F class targets all have 0.5MOA X-rings, 1MOA 10-rings and add 1 MOA on down. The standard NRA prone targets are 1MOA X-rings and 2 MOA 10-rings going down each 1 MOA after that.

My 300 yd plot sheets show this and looking on line I see that the MR 63 plot sheets show a 1MOA X ring.

Basically to score your round as if it was an F class target you don't have your X count, but you can score the points. Count count your Xs as 10s and subtract 1 point from all of your other non-X shots, i.e., 10s are 9s, 9s are 8s, etc...

I'll testify that the F target is very challenging at 1000 yds. with a 308.

I don't know what your X count would have been but your last two rounds would have been a 195 and a 194.

Move everything in one ring. Any 10s would have been 9s, any 9s would have been 8s, etc. Your Xs would have been 10s.

Your second and third string it looks like you didn't have anything outside what would have been the 9 ring... so you would have had a 195 and a 194 respectively on those two - not bad at all.

For your first string... spotters don't count in your score, period. There are some match formats where you can convert your sighters, but this wasn't one of them.

The X-ring on the MR63FC is 1.41" @ 300yds. If you think thats bad... the ICFRA 300yd target is 1.28" or thereabouts. At least their target has scoring lines that are easier to see! On my home range, shooting 300yds early in the morning sucks because of the lighting... even with a NF 12-42x the rings on a MR63FC are very hard to see... which makes aiming off very hard.

Re: MR 63c target vs F-Class scoring rings

The first string was tough because the target was thicker and it was hard to see hits.
We cut the centers out between strings and the replacement centers were thinner, that combined with the white backer and better light definitely helped me see where I was hitting.

These are the second 2 strings:



Note in the third string I overcompensated for the wind that took my sighters and held off 1 moa +/-. The wind was highest at the beginning of the string and died off.
Had I waited out the wind and not tried holding off my x count would've been higher.




Also, for interested parties:
I was shooting 155.5 Bergers out of my Remington 700 in an AICS that was rebarreled with a Lilja 10 twist.
Leupold 6.5-20 with a target dot.
I think that the rifle, in a tunnel, would shoot under .5" at that range. I need to learn how to drive it better.

They gave us 2 sighters for each subsequent string, the 2 9's in target one were my first shots and the high wide 10 and 9 on the left were my sighters on the second target.

I'd say the hook is set

I have a lot of fun shooting, and it has made me a much better and more confident hunter. After I shoot a couple of thousand rounds trying to hit a .5MOA x-ring at 800 to 1000 yds a deer at 300 yds or in looks to be the size of a barn.

I take it this was a walk-n-paste match - no target pits?

Good target service helps a *lot*!

Golf cart and paste.
We'd all pile on flatbed trailers and bounce out to swap targets.

They had white corrugated plastic board set up at a 45 degree angle on the target backer behind the black.
I think it was meant to catch light and make it easier to spot hits.
Spotting in the first string wasn't easy and I had a loaner Konus 20-60.
