Load Development

[Crunchy]

I am just not 100% how off the old chrono is.  Could a load with .5 MOA have that much of a terrible sd/es. If it is as bad as the old chrono showed I will have to make a change.  So shooting the the likely load range is just in case I need to tweak things.  I keep a log book and spread sheet for later reference.  Cant wait for it to get here.  Going to cut into my fishing time.

My magneto throws the group way low but not any more or less spread.  I adjust the scope up, no big deal.

Having solid data really gives me confidence, one never knows if if was me or the round when you are in the 1/2 moa range.

Just got my Labradar in the mail. Looking at the different methods as I just started reloading. Brass prep stage is done. Time to load. Looking forward to following...

get a battery brick for the LR~ they chew up battery life. it has a usb connection.. i don't even put batteries in the unit

Good deal, ok I’ll take a look at those, thanks!

I looked at the Labradar, but decided for me it wasnt worth the extra 180 bucks over the Magnetospeed.  With my old chrono and the new one when it gets here, I only use them for load work up, and to get final numbers for SD and ES.  For that I can just shoot into the dirt berm.  I probably do things a little backwards though.

Well I finally got the magnetospeed out to run my load work up.  71.3 grains of H1000 had an SD of 5 and ES of 15 which is plenty good for me.  I cannot believe how off the prochrony was. 

Question last go around I gave Leupold my numbers and had them cut my dial.  Should I do any validation out to 400 or 500 to verify the drop?  If I did, I am not certain how they would cut the dial different..  Experts say?? I think i have them my bullet G1 and G7.  Verify drop and give them adjusted G1 and G7??  Or is it overkill for hunting/shooting out to 800 yards?

personally I would just go mil or moa. Too many things can change your dope. You’ll be happy to did

Yes, I wasnt expecting that as a response.  Thought, yardage markings on the dial based on the ballistics of rifle/bullet.  I would have to check my rangefinder to see if MOA is an option.

In other words. Don’t worry about the custom CDS dial. Zero your rifle at your preferred  distance. Range what your shooting at and just dial your drops in MOA or MIL’s. Depending on if your turret is Mil based or MOA based. You can be a stunt pilot and have a Mil reticle and MOA turrets. You can use the Mil reticle and just shoot hold overs in the scope or dial your drops with the turret in MOA.

Let’s say your running a custom CDS dial and you have a shot from a ridge steep down hill @ 600 yards. Best start doing some math because your going to way over shoot if you dial your custom  CDS for 600. Easier to range then use one of many ballistics programs or pre made drop chart to compensate for the angle, dial the correct MOA or Mil’s and shoot. I usually tape a drop chart for each rifle to the stock.

[/quote]at less than 600 yards your biggest factors will be exact range and exact speed and bc.  Now let’s say your range is off by 40 yards.  Now your 6” high or low.  Now let’s say the temp you did your load work was a comfortable 63f and your bullets where zipping along at 3000 fps.  Few months go by and your hunting bear in September and it’s 85f and now your load is shooting 3060 fps or its nov and your hunting elk in the high country and now the preasure is 26.35” instead of 30.35” where your dope was figured out? Or you start a new lot of bullets and the bc is a little lower of higher?   Any one of these things isn’t a big deal but you start adding things together and you could be 24” high or low.   Now try and stretch it out farther than that and your going to loose confidence in your setup


Learn moa or mil.  Be forced to learn all the proper inputs and variables that can affect point of impact.  You’ll have more hits and higher confidence.

I reload for my hunting buddy. His max is 500 yards.  I have two different labels that go on the turret depending on where your hunting.  If you haven’t tuned your rifle to shoot 800 yards I would encourage you to.  Things can really fall apart past 600.  I have some loads that shoot .2 at 100 but 9” at 1k.  Some 1/2 moa at 100 but shoot 3” at 1k on paper. Not a rock or steel plate.

Ive shot out to 725 where I hunt and the dial was fairly accurate.  I do recognize that the variables are endless.  The only way to be more certain is to purchase a few more items such as a G7 BR2 and/or Kestrel to minimize the mistakes from variables.
