What’s a good f-class group at 300m?

[marchx]

I started to train heavily before next season 300m matches. Week after week my 10-shot groups are circling around 0.4 moa at 300m. I select lapua brass by weight, select bullets by weight, select primers although in case of br4 it does not make much sense.
I do no turn necks.
Squeeizing these groups down to 0.3 moa would be nice.

5 shots .600 to .750 inch. Look at Tack Driver Results from this year.

 

[F Class John]

Agreed. My goal at 300yds is .750 or less

I only have a 300yd range available most of the time aside from once a week at 600yds so I do most of my testing at 300.

You mean 10-shot .750 group? I am shooting off bipod and just wondering what my next step should be? Neck turning?

 

[jackieschmidt]

There were probably a lot more 1.250+ measure groups at The TackDrivr than sub .800 measured groups. And this was 140 shooters with the very best they could put on the Bench.

Realistically speaking, when on the 7 minute clock, if you and your Rifle can keep 5 shots at 300 meters under 1 inch measured, I would consider that OUTSTANDING.

At any range, the 10-ring is 1 MOA. If you can routinely group at less than half that diameter AND can drive that group to the center of the target, you’ll shoot clean with a ton of Xs. At any range, the X-ring is .5 MOA, so if you can routinely shoot smaller than that AND can drive that to be centered on the target, you’ll shoot clean perfect (200-20X). Shooting smaller is always better, but better than clean perfect?? If you’re shooting groups smaller than the X-ring, but those groups are landing in the 9 ring, your group size isn’t the issue. Again, if your groups are centered on the target, I guess I don’t understand the purpose behind your question (as it relates to F-Class).

If your gun/ reloading skills/ and driving skills are 100 percent. You still need to become a wind reader ...this can take years.

 

[clowdis]

IF I'm not mistaken, I think the NRA F-class targets have 1/2 minute X rings. So if you're shooting as good as you say you are you should never lose a US match. But matches are 20 shots plus sighters. For metric targets I don't know what the ring sizes are, I think they're smaller than the US standard targets.

.4 moa 10 shot grp at 300 meters is pretty good, what size 5-shot group are you shooting at 100 meters.
I would suspect you are going to have to shoot .150-.200 5 shot grps at 100 meters in order to shoot under 1.00" at 300 meters due to dispersion and weather.

I looked up (googled) the X-10 Ring Metric F-Class target size as I didn't know. ISSF Standard
F-Class metric targets at 300 meters

• X-ring: 50mm (1.96 inches)
• 10-ring: 100mm (3.94 inches)

Google was not a good reference.

My apologies- I Looked up the ICFRA International Rules

B2. The ICFRA International F-Class Target (Short Range) B2.1 A V-bull ½ the size of the TR V-bull within the ICFRA International Match Target for short range, with the original v-bull counting bull-5 and so on viz:- (All measurements in mm to the outer edge of the scoring line) Distance 300 yds 500yds 600yds 300m 500m 600m Aiming Mark 560 915 915 600 1000 1000

300 METER

V-Bull 32 MM 1.259 in
5-Ring 65 MM 2.559 In
4-Ring 130 MM 5.118 In

In your training, are you replicating match conditions and targets for score? By mentioning group size, this suggests not focusing on steering to the xring which i think is more fruitful.

Yes, I do. I shoot at official F-class target. 10 minutes for 10 shots. I usually get 50 points and around 4 or 5 Vs. It is however training. During a match I have to shoot 5 series (50 shots total) and usually drop 1 or 2 points. I think it's more adrenaline than it is wind at 300m, rather pulse, rifle stabilisation, so pretty basic stuff.

 

[Fuj]

After 4 group targets at the 300 meter Tack Driver......Eric Cortina was
only averaging 1.3718". I will note though that he is not used to sitting.
and shot himself in the foot with that Creedmoor cat he brought. Should
have brought the big gun and I think it would have been much tighter.

I would try to hold 3/4" as your high mark.....

Thanks. Then, the ISSF targets are larger (proportionally) than NRA targets. NRA F-class targets are crudely 1-MOA per ring, except for the X-ring which is 1/2 MOA. I say crudely as they generally use the “shooters MOA” of 1 inch = 1 MOA at 100 yds. Per NRA rules, the 10 ring for the F-class 500, 600, and 1000 yd targets are 5”, 6”, and 10” in diameter (with X-rings at half those diameters). Oddly, the 300 yd 10-ring specification is not 3”, but rather 2.85”.

1 MOA at 300 M = 3.436", so if the ISSF 300M 10-ring specification (as @foxguy posted above) = 3.94”, the ISSF 10 ring is larger than 1 MOA (1.14 MOA).

1 MOA at 300 yd = 3.141”, so the NRA 300 yd 10-ring at 2.85” is smaller than 1 MOA (0.91 MOA).

I have shot 750/750 on the ISSF target. If they had been using the NRA target, I would only have gotten 748. That rifle was a solid .3moa rifle. If I remember right, my best 100 shot match on the ISSF target was a 996. Might even have been 995. Shot that with a 303 British though. Lost out to a damn 6BR. Recent events would seem to indicate I have lost any abilities I once had, so my thoughts may not be relevant. Nonetheless, if I have a rifle which will stay around .4, I feel I could do OK with it, recent events notwithstanding! WH

There's your answer. The load is capable, it's the trigger nut that needs more tuning as usual. Me too!

If you shoot at Bayou rifle club better be able to shoot 600-50x's plus. The average winning score this year is probably around 53X.

September Bayou match Sam and Miguel put on an X shooting bonanza! Both shot aggs of 600-59x both shot in the bonus X race for the record 2 times each.
Sam shot 28,19, 28
Miguel shot 29, 19, 28
So they both shot piles of X’s for that match.



Incredible how well those rifles shoots in that volume with conditions 1 single flag.

 

[Rope2horns]

Add Damon Martin, @Daerider to the list of 600-59x group. That's the only three dudes I know of that have shot those scores at 300yrds. Damn impressive IMO.
