It’s all in the photos tikka .308 178eldm 2206h fed 210gm same charge 8 thou difference
so you used same amount of powder with a 178grn pill and a 210grn pill??????
you changed a shit load more than seating depth if Im reading that right.... and thats a very dead deer either way.
Federal 210 Gold medal primer, sorry I over abbreviated haha
@Micky Duck fed 210 is a primer size.
Whoops to late!!!!!!
yeah bro... then the next thing is get a good mandrel expander set and youll see it change again! my 7mm saum shoots like this... has to be precise otherwise thr groups open up like your top pic... so i have to make sure EVERY load is perfect lol
That's why when I do a seating depth ladder I go in 3 thou increments, if you go 10 thou you coupd skip right over a node.
Then again you can get luck too, I did a charge ladder last week seated at Saami in a 308win and found a brilliant node, only cost me 12 rounds to develop a 1/2 moa load :D
This was 15 rounds mate I did 12 seated at mag legnth because that’s how my usual tikka load d goes but then knocked it back to saami and money shoots all day long . I was going to start with seating on a safe charge then work threw charges but as above I’m use to being clapped at the heels with mags so figured mag fit would be the depth I was wrong , Note to all if you don’t want to muck around with long action mags and bolt stops just buy a .308 eh
That's an impressive 2nd photo cluster of shots but Call me pedantic, in hunting terms does the difference between a 1 moa and .4 moa really matter? It obviously does in target shooting but in the field where the target can be as large as 8 or more inches both will be acceptable to at least 400 yards, and how many of us honestly shoot animals further than that on a regular basis?
At 400 or 500 yards with a bit of wind, especially gusty cross wind I’ll take the 0.4moa load every time. Does wonders for your confidence too.
I guess it just comes down to how far your actually shooting. Most people dont shoot that far but theres more & more out there pushing the limits with longer ranges these days. Variables like wind, shit rest/shooting position, temperature especially running powders like superformance etc, average operator on the trigger all play a part so if you can make the grouping part of the equation as good as possible its one less thing to go wrong. At 100m the difference between .4moa and 1moa isnt gonna make much difference at all. But at 400 yards, ill admit the difference still isnt huge for the likes of a deer, .4moa is roughly a 1.6 inch group? Wheras 1moa is a 4 inch group. If your starting at 4 inches at 400 yards and only getting worse from there as far as a bad wind call or any of the other variables, its just more potential for things to go wrong.
You could call me pedantic with my reloading but as chainsaw says confidence is your biggest asset when making shots and knowing the rifle can stack them really helps and again if you multiply everything in 100mtr increments I pick .4 . This is the guys only rifle and it’s do it all farm rangers to alps, it sports a Leupold vx5 and he has a self imposed respectable limit of 450yards while I’m sure the first load would be OK at that range the second leaves less to chance yes abundant no not native but none the less we strive for fast clean easy to find animals
Keep us posted will be interesting to see what velocity you end up with.
I'm running a 22" barrel so gain a little there over 18"
ADI data suggests you'll be around 2400fps taking into account shorter barrel but not a hot load not that it matters.
An old reloader said to me the trick was the toilet seat. The projectile gets a nice seat on the powder. If you sit your "...." off the seat it is cold and chilly. Much like kissing. Nicer to have your lips on her , rather than peckering in the breeze with your neck out. He was not a fan of a droopy projectile. His other view was that in modern parlance there was no turbo lag with the powder launching off the projectile. He was a triple deuce king. Each to their own.
From memory my old load that I use to pay to have loaded for me in christchuch(ex ballengers hnf guy Jason Adamson moved to Ashburton any one know if he’s still around?)many moons ago was 2372fps with a 180sst and a 16” tikka .308 presumably 2208 so I’d say your about spot on with that adi data mate
I learnt today that the 63grn load for my triple duce needs to be seated deeper.......hmm why wont round eject,then case came out leaving projectile in rifling and powder all over the show...just aswell the pack was already fill with venison.
Is that the first time it’s happened? It happened to me about 6 weeks ago in the .223 after about 30 rounds for the morning never happened before and I’m not jammed think their must have being abit of crud in their that grabbed the projectile . Iv also had it happen a couple of years ago with a 6.5saum was getting a false feel for the lands and it just wouldn’t shoot turns out I was jumping 120 thou I got a comparator and measured a round that came with the rifle that was seated at 20 thou and instantly problem solved very frustrating powder waisting load development that was
first time yes...may have just had that round seated slightly further out...will measure up the other dozen of them I have loaded.
hmmm think I have some on the shelf...might have to try them.
Have you had an opportunity to go back to the range and repeat both these three shot groups with exactly the same ogive to case head length? How about two three-shot groups at each length, twelve shots in all, and put up the pics here. If you PM me an account I'll reimburse you the $30 for the consumables.
Hey @Puffin iv given the rifle back so it’ll take me some time to do that I shot the 15x 2.810 5 lots of three at different powder chargers then picked a happy medium in the ladder and loaded 2.800 2.805 2.820 and 2.830 I shot the 2.800 first for the tight group up top and bumped the remainders back to 2.800 to save the primers
So how far off jamb was the winning depth? I'm guessing .o4 or 5"?
@Kelton you are onto it. Just about finding the sweet spot in your rifle !
Here's another example:
Attachment 215511
The results speak for themselves although I'll be testing the indicated depth with a couple of 10 shot groups. it also pays to observe the shift in point of impact, a stable POI also indicates the node.
