Whats a good SD for a rifle load 6.5 creed

[tiger49931]

Took a couple box's of match ammo out and ran it thru a MPA BA PMR in 6.5 creed over the chrono and over 60 rounds got a SD of 36.867 with a mean of 2791 but the factory Hornady MATCH ammo 140 ELD had speed ranged from 2711 to 2869 that's over a 150 FPS swing in a box??? When you guys reload what kinds of SD's are you all getting? Cause 36 seems high to me but I'm used to pistol reloading getting single digit SD. Can you get the same with rifle? TY in advance..

If you can reload with SDs into the teens that is pretty good...

Some people claim single digit SDs but over 3 or 5 shots.

You need to do at least 20...

Was able to get an SD of a little over 7 with starline brass. Was honestly shocked to be honest. Have yet to shoot at any type of distance yet, but that is planned for either this week or next.

Which chrony?
Was just one or a couple shots Really high or low?

teens and single digit SD aren difficult to get.

This right here OP, is pretty good. Especially considering that he did not do it over 3 or 5 shots like some do lol...

Mine was just 5 to get a base line from multiple loads. Loading up more to get a few larger groups to see what happens

Agree though, that shooting fewer rounds really doesn't show the full story.

yeah my SD was taken from 60 shots of boxed Hornady match ammo. Over an alpha chrony with fresh battery and a partly cloudy day. chrony set at 10 yards (25-28 feet )

Your chrono is returning bad data

I would guess 6.5 Creedmoor.
I never look at SD. ES is all I care about. Keeping it low double or even single digits tells me I have good node. If the ES is low, so must be the SD.

Shot this load at 200 yards yesterday. Only 7 shots. The 4 that are stacked are .16moa!! The other 3 opened it up to .47moa. Still a contender and I’ll massage it a little bit on either side and see if it’s repeatable.

Get a Magnetto Speed or Labrador if you are serious about accurate data. I have had several "Light" chronos over the years never had great results with them they always seem to exhibit erratic behavior.
I think good SD is 20 or below great SD single digits.

Here is a thread I started a while back should give an idea of what other people are getting.

Range Report - Chronograph Reports With Factory Box Ammo

I am not sure if this thread already exist somewhere else, but I thought it would be a cool idea and useful information for people to post their shooting data for factory box ammo so here goes...... Factory Box Ammo: Prime 6.5CM 130gr Chronograph: MagnetoSpeed V3 Rifle: Tikka CTR 24" 6.5CM...
