So i can finally check these reloads ( Chrono Thead)

My in laws.. being the wonderful people they are ( They really are awesome) Picked me up a Chrony For Xmas :D Wife helped em out too.

ANYWHOOOOO. Its a Beta Chrony. Today i went to the range and of course last time i was playing with it at home i left it on and the 9 volt was TOAST.. was able to shoot 1 string through it and wasn't able to use any of the features to calculate anything. Here is my 1st string i recorded load is as followed

55gr Pulled M193
23.5gr TAC Ramshot
Mixed .223 brass
Federal Small Rifle Primers
OAL 2.220

1. 2673
2. 2611
3. 2648
4. 2662
5. 2671
6. 2616
7. 2683
8. 2795
9. 2609
10. 2673

So.. Question being what is the typical thing to do with these numbers i realize i want to get a average and the standard deviation as well. And compare load data.. But is there anything else i can gain from this? Thanks GTR just making sure im not missing out on anything..

Hope your christmas' was full of primers and powders :D

The chrono is a key tool for reloads. You have some consistant numbers there ( a good thing) - enough to draw some conclusions about the load. GlenwoldeWhat's the gun and barrel length? They are a bit on the low side for 223. What is the powder (and load) and bullet? Did you test for accuracy? Fill us in - you are off to a great start!

I use 24.5g at the same 2.200 OAL, in both my 16 and 14.5 inch 1-7s they average above 2700 FPS.

Does having a almost worn out battery effect the accuracy of the readings?

Just make sure to test that they cycle with dynamic moment and different shooting positions, when you get a chance.
Good looking rifle BTW... I like you choice of furniture and accessories? What handstop is that next to the Allen Keys?

Change out the 9V in your smoke detectors you cheap bastard. Then, keep all the perfectly good 9V's that were in your smoke detectors in your range bag as spares for your chrony (and shot timer).

:D
SD is 71.11
Avg 2664
Rng 74

Check your cases for volume by weighing them and try to use matching head stamps. It doesnt matter how fast your shooting them what does matter is how tight they print.

If you need to slow down do it vice versa and watch out for signs of high pressure.

If you have good groups and you have a constant velocity you can calculate your bullet drop and reach way out there with 69 grains.

Ftwfwd,

Congratulations on your new(est) toy.

Here is a site that might make this easier;

http://easycalculation.com/statistic...-deviation.php

Another thought here is that you need a "standard" in order to compare your numbers up against. What I do I go out and buy a box of your most trusted factory ammunition, run them through your chrono, and of course you have the numbers given to you in your load manual. Now you can compare your results to those and this will give you a ball park as to where you are at velocity-wise.

From the Standard Deviation numbers you can determine if your charge loads are consistent one after another. Don't get too nuts following after SD numbers, this is best done in a laboratory not at a range. However it will give you a firm guideline which you can work from. The best use of these numbers for the average reloader is to try to be as careful as you can to throw & measure the same charge amount every time... as best you can.

Watch for pressure sign as you see your velocity increase, and keep all these numbers written down.

Have fun and be safe

Thanks man. I put everything into an Excel File and Calculate everything at the moment. Keep the date, powder, primer, temp, etc, etc. Works pretty well! Thanks for the advice.

Some advise... do not get overly concerned about velocity when working up the loads. Especially for rifle.

1. Determine your powder load range (min to max)
2. Work up your loads slowly in increments.
3. Test for function in your gun and accuracy.
4. Find your best load accuracy wise, fine tune at that point.
5. Chrono and record data.

Ever gun, bullet, powder combo is different. With riifle loads you will find low and high nodes for best accuracy. Which one you choose to stay at depends on your intended use.
For example my 69 SMK load for my R700 is just at MOA at 100 yards but well inside MOA for 200 and beyond.
