Favorite Target Style - Load Development

[Tommie]

These are at 500 yards, first group was before my stock was painted and second group was after Brett painted my stock. My new load development process is to have my stock painted, saves components, I call it painting node, lol

Funny, yes. But there's probably a smidge of truth here as well. Brett essentially "blueprints" the outside stock surfaces which can, and likely does, improve tracking.

I'll say it again: When BC'z paints a stock, there's a WHOLE BUNCH of other goodness that goes into it in addition to just paint.

I just installed it for my iphone but it doesn’t show me the pressure in the forecast

I shoot charge weight 1st, this target was shot at 100yards 3 shots per charge 123gr Amax set at touch. Pure shit house luck on the 45gr charge of RL19. I'm looking for horizontal poi, 45.3 measured @.22" C.T.C. 45gr was .098", I chose the 45gr to compensate for temp increases knowing ill have a lil wiggle room, and any increase in charge weight would be compressed leaving no room for seating any deeper in case. This load shot .5" group @300 yesterday and under 2" @ 600.View attachment 1327688
Normally after determining charge weight I'll run seating depth test off charge weight test.
3 shots per target in same format moving bullet deeper in .003 increments. You can see how seating depth tune repeats itself. I loaded on front side 2.2460 on this particular load.View attachment 1327696

Excellent! I have a question: You are doing 3 tho jump increments. But are the bullets that consistent on the ogive? As well as on the jamb measurement? I use the hornady oal with a cleaning rod and my variation in multiple measurements to lands is around 3-4 tho with the best consistent touch I can get feeling the lands. And then yesterday I measured a bunch of my 168gr 30 cal amax on the comparator and I found it hard to find a 3 tho max variance. Its hard enought to get the casing base to sit perfect on the caliper arm to consistently measure to the tho. Thus for measuring jump in my non br rifles I use increments of hundredths ( or 10 tho's)

Great question!!
I had sorted these BBTO a couple years ago into lots of .001, after listening to Bart Sauter explain the benefits of sorting OAL i checked a dozen, amazingly they were all within .0015.
I've been doing random spot checks on the batch I'm taking a break from now, and I'm only seeing .0005-.001
Variation in seating depth BBTO & OAL. The tolerance is built into the load by setting charge on back end of window and seating depth on the front side of window.
Now its back to finish these last 10 rounds.

I guess I’ll be the maverick with a piece of freezer wrap paper a couple sharpies and a wind flag.

I like this one.. . . .

I like that! How is the paper? Is it nice and thick like card stock or thin and flimsy?

Arrived early...paper is a little thicker than standard copy paper. 25 sheets for 4 bucks...very happy with these.

Ok! That just reminded me of a trick I invented in the past and forgot. I used a second hornady comparator with a 17 cal insert to clamp on and use as a base for the casing to sit on when measuring oal to ogive. Was way more consistent than moving casing base around on mic caliper to find the center shortest spot. Might try it!

i just make my own with a ruler and marker, its just easy and just makes it easier to see where your nodes are
this was my 6BRX at 300m with 105gr hybrids and 2208/varget , i now use a red marker as your bullet holes don't get lost if they hit the black line.
i settled on 32.4gr and i didn't have my labradar set up so i didn't know speeds but 32.4gr was 3000fps when i did test it,
the last shot was also me as i didn't mean to pull the trigger but i had a faster node at 33.6gr but decided against it as it would of been hard on my brass

I use Sinclair 1" black target pasters. I use one corner as the aim point. It's pretty easy to get a repeatable hold using this technique. I think I read about it on here years ago, LOL.

It would be great if you could post a few pics after you get a chance to shoot some of these targets. If they make nice clean holes, I’ll probably place an order.

I like it !
Well done my friend..

I prefer this style. I designed this one myself for 100 yard load development. The center dots are 1/4” which is the size of the floating dots in my Sightron scopes at either 20x or 24x. I can also adjust the dot size bigger or smaller to fit a particular reticle or scope power. I like to watch my point of impacts change in load development and having 6 targets in a row makes that easier to see and read for me. Having more in the same row would be better but I wanted to be able to print on standard 8.5x11 paper. I use card stock paper to print on and it makes a really nice durable target with clean bullet holes. The square box below the aiming points I fill in with the bullet jump for each target when doing seating depth testing or powder charge when testing powder charges.

Here is one which I use. The 1/2 diameter circle has a 0.218 white which allows a little white around a .125 dot. It is easy to center a dot in a small white circle. The squares are 1/4". I sometimes offset the impact point down to preserve the white circle.
I open the pdf on my computer and print the targets on my ink jet printer. I print them on the back of targets that I have purchased in large quantity, and have cut down to 8 1/2 X 11
I use the top and bottom two targets as sighters or cold bore shots. I use the upper corner to write in the gun I am using, large enough to read through the scope, and the lower righthand corner to record temperature, humidity, atmospheric pressure and general wind direction and speed. With 20 targets on each sheet, it saves a lot of running down range to change targets.

I record the data on a sheet that matches the targets. I record the Labradar data for each target after each 3 or 5 shot string. I also record the seat depth, and Labradar series number.

When I get home, I check the group sizes with On Target, and write on each target the load, seat depth, average velocity, ES, SD and group size. This target and the data sheet then go into a folder I have for each barrel.

Another. Print as many as you need when you need some. You don't need anything more.
