Went shooting today, tried my hand at the 1/2" group challenge. Went ok, but none of my groups were 1/2" or under.


I suggest, anyone that wants to post their progress towards the 1/2" challenge can post it here.

The rules are simple,

- shoot a minimum 5 groups of 5 rounds each, they must be obvious groups, and you can not have anything in the picture that is covering a "flyer".

- take a picture of your rig just as it was when you were shooting the groups. Including what you used for a rest.

-take a picture of your target paper with all groups visible in the picture. The group sizes must be written on the paper beside each group. **since we are not competing yet, you can have more than 5 groups, but they must be counted in the target average.**

-When measuring your groups be sure to measure the groups properly. Measure the extreme outside spread of your group and then subtract the bullet diameter.

- Calculate the average group size, and post it with your individual group sizes.

- Post your rifle, optic, ammo, # of groups, and rest info.

- repost if you try again, progress is encouraging.



Here is my first contribution:


Rifle: Remington 700 LTR in Cadex strike 30 chassis.
Scope: Vortex Viper PST 6x-24x FFP
Ammo: 168 gr Norma Match
Rest: Harris bipod and rear beanbag
Range: 100Y
Groups: 5 rounds

I am still pretty new to precision shooting.
I will be trying different holds, and shooting techniques. I will also eventually switch to hand loads.
I would also like to buy a defiance rebel action, and mate it to a Bartlein Match barrel... Eventually...

Group 1 = .688"
Group 2 = .688"
Group 3 = .509"
Group 4 = .798"
Group 5 = 1.029"

Avg = .742"

Anyway enough talk, here is the pics:






Now the real kicker... the other rife in the first picture is a Mossberg MVP in 5.56,
It is mounted in a MDT LSS with a Bushnell 4200 elite tactical.
Best group of the day with it was .350" with Hornady 75 gr match.
The other groups with other ammo were all about 1"-1 1/4"

I actually like the idea of this thread. It can be a place to show how well your rifle shoots. If you, or your rifle aren't up to the challenges yet, you can post here using the same basic guidelines as the challenges. To the OP, I hope this was your intent for this thread. It's a good idea.

I was going for that, I want to see where I am at, and hopefully after a few weeks I can post improvement.
And I agree, for anyone else that wants to post their progress, please do...
I love shooting sports, and whether on the forum or on the range, I will gladly talk and listen to others who enjoy their hobby.

Where's the distance?

I removed it since the measurement is linear,
I suppose that if you want to shoot at 200 and divide the score by 2 feel free.

I guess I should stipulate that minimum range is 100y.

edit: Added range and math to determine MOA
 
Well my rifle/me definitely does not shoot 1/2 MOA yet, but I was at the range doing my load development and took some pictures unaware of this thread, so here it is. Daver_II, may I ask where did you buy your targets? I was recommended to use this exact targets because it has a better defined point of aim.

Rifle: Remington 700 sps varmint 26" barrel 1:12 (factory rifle no alterations yet)
Scope: Vortex HS-T 4-16x44 SFP
Ammo: 168 gr Honady HPBT
Rest: Front/Rear (bird seed) bag
Range:100m

Group 1: 1.082-.308=0.774
Group 2: 1.905-.308=1.597
Group 3: 1.430-.308=1.122
Group 4: 0.876-.308=0.568
Group 5: 1.239-.308=0.931
= 4.992/5=.998"
Avg = 0.998"

Mine are from taskforce targets

h ttp://www.taskforcetargets.com/#zeroing

but another option is these ones from le targets.

(take the space out of the http.)

they are smaller and have the small aiming squares as well.

this is another good option.

Thanks Daver_II, for the info. Sorry I couldn't post the pictures for some reason they don't make it easy. Just out of curiosity, how do you like your Vortex Viper PST? I am having a hell of a time focusing with mine.

I like it quite a bit,
The real pain in the ass is getting the parallax and diopter set up properly.
But once you do, the clarity is very good for a $1000 optic.

Many people forget about the diopter setting.
Also don't forget that the parallax setting numbers may not be exactly accurate,

There are some really good videos on youtube that tell you haw to set up your scope properly.

I think they are stickys in the precision forum.
 
Diopter setting, was something that I over looked for sure and that would explain why I could not focus on the target. I don't know how I could miss that one, thanks!
I know for a fact that parallax setting numbers don't line up, at hundred meters it reads 60, but that is a non issue when it comes to the big picture.

I haven't really put my scope to any tests yet, because I shoot different loads every 10 rounds, but so far it seems to track well and does what it suppose to really well.

Your groups look very tight vertically and horizontally now that is impressing especially from a bipod. I had to abandon my bipod because it was jumping too much and I noticed a big difference when I switched over to a bag. What have you done differently in target #5?
 
Definitely recheck your parallax once you played with the diopter. ( I recommend using a light coloured wall and fast adjustments.)

Your parallax will likely be much closer to the scope settings once the diopter is set better.

I am really trying to keep using the bipod, even though a bag is often better.
I am really not sure what I did different target 5, I was trying to be pretty consistent.

However did have to reload mags after target 4, so maybe I repositioned. (or maybe I rushed, not sure)

I definitely see what you mean by pain in the ass setting up the diopter, How did you set yours? I took mine out all the way towards my eye until it got out of focus and then slowly turned it clock wise away from the eye until it got sharp. At this point my reticle is the closest or I guess it appears to be the largest and the most crisp. Now where I see a problem is at this zone because I can still adjust my diopter away from my eye and still appears to be in focus, as the reticle gets smaller as it gets further away from the eye until it gets out of focus, the reticle appears to be the smallest. Do you go to the extreme high end or do you go to the extreme low end? My scope was on the extreme low and which would explain why my parallax was so far off from the scope setting. I will try it out to see how my focus got better with the diopter set properly as soon as I can go to the range.

This kind of brings up another question, If by adjusting the diopter actually changes the size of the reticle and if it is not set up correctly the FFP reticle is pretty much useless for ranging your target. Does your scope has a mark for the 0? Mine doesn't.

When you set up your Diopter you should be in a well lit area, and against a plain light background. I did mine on my dining room table pointed at a light beige wall.
(sky or cloud works well too if you do this on the range)

Be in a propper shooting position with proper eye relief when you do this.

Start by zooming in to high magnification, and pick a spot in your reticle.

I used the number 2 in the 2 mil mark (my scope is mrad and has small physical numbers at certain parts. EBR-1)

then focus your eye directly on the number,

move the diopter until the reticle is close to focus.

Now for the tricky part... your eye can compensate for the reticle being out of focus, and this is what causes strain and fatigue when you are shooting.

so to fix this make the adjustments quickly, and look away often. If you make slow adjustments your eye compensates too quickly.

You will go past focused, and then back the other way, getting a little closer every time.

Eventually you will get to a point where it is focused perfectly.

The retinal changing size is really misleading. once everything is focused and aligned the ranging will be bang on too.

What do you mean by the "zero mark"? do you mean for the diopter? parallax? windage? elevation?

I am happy to help.
 
Here is a great video of how to set up your scope properly.
This youtube channel has a tonne of great info for precision shooting.
I have watched them a few times and I still learn things from rewetting them
it is a great resource.
