What does your average 100 yard group look like?

[Ranger188]

The OP wants a ave. 5 shot group.
Ran out this evening and shot 2 x 5 shot groups. Trying two different seating depths.
This is an average 5 shot group @ 100yds. with bipod and rear bag.
(edge to edge a little over .5 so .3 ave. Thats a bushing for size comparison 6br)

 

[yej0001]

My rule of thumb in load development is if groups of five 308 bullets consistently touch each other at 100 yd, I stop fussing about it. For 6.5 caliber I gave a little more room.

Is that a tuned powder charge?

 

[Ranger188]

It was close. But when you change seating depth you sometimes
need to adjust the powder charge.
As you see they shot close to the same POI. I might try a .1 change in powder charge
either side of what I shot to see if that would tighten up the group slightly.
I keep all my targets and only adjust one thing at a time.
As a lot of shooters here, once you've shot a certain caliber a couple of barrels
you know where to start for load development and not waste a lot of time and resources
on it. ( might start .5 low) Once you find a nice load, you'll then take it out farther and see if it repeats at distance
most times it does. A good load at 100yds. is most likely a good load at distance.

Thanks Sheldon for posting the match results with the group sizes. It’s interesting the group sizes do not really correlate with the match standings. One shooter in the top 10 shot about a 1.7 MOA group! At the same time a number of shooters shot impressive groups but didn’t fare as well in the overall standings.

Oh yea, you definitely don't need a 1/4 MOA gun to win the match. The second day was pretty challenging, 90 second stages with a lot of movement, some wind, and shooting with a lot of terrain in a 360 degree circle so you got exposed to new wind almost every stage. It was a ton of fun, but you had to be on your game to place well.

I’ve had a few stellar groups, but overall 6.5x47L in a factory AI makes things easy from an “every group during load development” standpoint. Realistically for me I’d say 1/2 MOA avg, 3/4 MOA max, 1/4 MOA with a cherry picked group with my match load.

Best group I’ve shot in my life was a literal 1-hole 5 shot group where I laid down at 12x on my scope and cranked them off. I think there may be something to subconsciously shooting them versus taking tons of time focusing on each shot and inevitably yanking one.

This is probably the best 10-shot group I’ve shot, POI was up due to the magnetospeed.

Here's an interesting piece of data from a recent NRL match where group shooting was part of a stage and group size was recorded as the tiebreak for the match.

You had to shoot 4 rounds from a barricade position at steel targets, then drop prone and shoot 4 rounds onto paper at 300 yards, recorded by an electronic target. Groups size for the four shots was recorded. You had 90 seconds to complete the stage so no dicking around.

125 shooters at the match ranging from experienced pro shooters to your casual match competitor. You can see the group size listed under "Time Stage 16" in the first blue column.

So when it counted and under pressure most shooters were around 2/3 MOA. A few dropped below 1/2 MOA (1.5" group) and a handful shooters were under 1" for four shots. And there was only one shooter who "did his part" and broke the 1/4 MOA all day threshold.

No surprise it was the Snipers Hide Cup individual winner @Piper907

Awesome Post!

Hell yeah, I don't know why but that just makes me proud to be an American, that around 75% of the field at a random match, which definitely has a some top level guys but still a lot of normal guys that work full time and have families, shot sub moa on the clock in a match setting on the spot

I get it that sub moa from prone is not that hard with a precision rifle and nice optics but it's still puts a smile on my face for some reason

 

[Campguy308]

Did some load workup today with my 6.5cm and 130 vld. Really happy with the results. Tweaked the seating depth on the 140 eld load and tightened it up. I feel better now lol.

 

[XTREM HTR16]

My typical for my 6.5 SAUM hunting rifle. Working with the 139 Scenar now, gonna just stay with that bullet from here on out.

Earlier this week.

 

[gunsnjeeps]

Today's 100 yard slow prone. Home built AR-15, Vortex Viper 1-4 (My current match rifle.), MK262MOD1, 100 yards. 90 degrees and killer humidity.

Called flyer 7 at 11 is 3.66, the other 19 are 2.8. Not sure how I pushed the one at 2 O'clock out there but I'll claim it.

ETA: Sorry guys, just noticed this is on the bolt action board.

Yep, peeps can say what they want about the Mspeed not being for load development but mine seems to do its thing with the only impact being groups at 1/2 MOA higher than they would be without it.

My MagSpeed shifts my POI about 1 mil up on my Tikka sporter barrel and .3 mil up on my 6.5 creed M24 barrel.

Other than that everything seems to be the same as without it mounted.

Regular groups are between this:

And this:

Some days I can get the good old one hole group, but on average they are between the two 5-shot groups above. I use this little bugger and 175 grn SMKs & 43.5grn RL-15. Loves em.

Where did you get the tiny targets?

 

[kingston]

Jesus

 

[LongRangeLefty]

RPR .308 SWFA 20x42/Harris/190 SMK. This rifle shot a .117 but this is more the norm.

 

[Genin]

Where did you get the tiny targets?

They are just smaller targets on larger regular targets. The small silhouette is the one that is on the upper left of larger silhouette targets and the small diamond is on the top parts of diamond zero targets.

 

[sea2summit]

Haven’t started chasing loads yet but this is the current project. LaRue OBR converted to .260, factory Hornady 130s right now.

100m, not converted.

100m...never do maths in public

 

[lash]

Doh! Of course, that makes sense. I haven’t bought a commercial target in so long that it didn’t occur to me.

Btw, great shooting!

 

[Novak77]

Def not breaking any world records lol. 5x rounds of 168 FGMM out of the wife's TRG. My groups out of my 595 Master Sporter ain't that far behind.

 

[seansmd]

10 shot group with magneto speed attached, new Prime 6.5 CM recipe!

 

[Undrgrndprdcts]

Old Prime. Top round was cold bore.

 

[L-Ray]

These were when I was doing break-in on my CA MPR in 6.5 CM. Center and upper right are Nosler 140gr, Lower left is Hornady ELD-X 143gr and lower right is Hornady 129gr.
