Maybe that's the first bad review of the super chrony?
I dont know anything about them but knowing it works off sound I would think it was critical to ensure the chrony is level or at least the projectile is traveling over each of the sensors at an even distance.Quote:

it was set up according to the instructions
im sure that they wouldnt release a product onto the market without severe testing 1st
it surely wasnt out of whack testing other rifles today
303 was doin 2600fps factory highland 180grs
my 300wm was doin 3600 fps 168gr amaxs
Ok. Something is not right tho. 3600 for a 168 out of a .300wm and 3700 for 55 out of a .223 is way faster than what would be expected, no?

max loads according to ADI
300wm 75grs 2213
No one is saying the load is to hot. I think we're getting at the fact that the chrony seems to be reading very high.
Give what book speed? 3600? I would have thought around 3250ish?Quote:

That load in ADI's loading manual gives just on 3000fps that's a long way off 3600.
but yes you are correct it seems way to fast than it should be
How far does it say to set the super chrony away? Are you using suppressors?
Ie is it effected by muzzle blast like an optical one?

I had it set between 3 an 5 meters from the barrel from memoryQuote:

As I said I dont know much about them.
If you shot over it as instructed there can be only one thing at fault.
Gaining 50 fps second without major component changes is hard enough.
Your gaining hundreds from book values.
Let us know when you do somemore loads. I am curious and interested in one of these chronys

I would have said .223 but after re-chambering I'm going to say .223AI
Lapua brass.
2?.5 Varget.
55 V-max.
CCI BR4 primers.
3500fps from a 22 inch barrel still at a sensible pressure.
Very little brass trimming.
Still fires parent .223 very accurately.
Going to get hold of some of the 53 grain V-max as the BC is better than the 55s and should put this loading up there with the .22-250!
If its windy I reach for the .270.
22-243 with 30g bergers at over 5200fps... Just putting it out there
Does it burn out the barrels fast?
Love my 1-7, 22-243, 90 Bergers dawdling at 3100, scarey accurate way out there :cool:
My 1-14 is fun with 50-53 at 4200 & 30s at 5200, a little ballistically challenged compared to the 90s though...
I really like my 204 with 40V-max at 38-3900 but it is going to make way for my new toy :)
The 22-204, I'm very impressed with this chambering, it is like a 223ai on steroids, with no fireforming, simple dies, good brass :cool:
Speeds with the Oehler 35p, 53 Vmax at 3700+, 75 Amax at 3200+, 80 Amax at 3100+, 90 Berger at 2800+ all out of 22" 1-8 Tikka.
The 90 Berger wasn't stable & wouldnt shoot, I did it for speed testing & will chamber one in a 1-7 barrel soonish.
My own rifle will have a suppressed 20" barrel so will be interesting to see the velocity difference :)
The small case has a few advantages over the 243 case, less powder, less noise, longer barrel life, less weight :cool:
Cant believe your 204 hasn't sold yet Greg
I'll give you $1500:thumbsup:
Yep quite surprised myself.Quote:

The targets probably didn't help either, as you can see, it shoots like shit.........:XD:
Thought I would have sold the 308 as well.......
Can't really see the sense in giving them away.........
Don't really no who would want a 308 so i can understand that one not selling:thumbsup:
223 WSSM is top of the pops by a long shot.:thumbsup:
Until you bump into the 22-243 :DQuote:

If you have a look at data for them they tread right on the heals of a 22-250 for a bit less powder & very easy to get shooting well without a lot of messing around.
I form cases out of 6BR brass but it's very easy to do, just run them through a 22BR FLS die & then a bit of a neck turn (for my rifle) & all ready to go.
Shoots my 52gr Targex into one hole & the 69gr Targex go into .25" @ 100m. The little water balloons at 500m are a bit too easy so we are going to try them further out sometime. My two boys got bored with it as they were getting them every time.
This would be my pick for a straight out varmint rifle cartridge but for a target & varmint I would go 6BR but obviously there are a lot of different ideas out there which is what makes it all interesting!
The only real accurate 50 is the HMG if one round misse's the other ones will soon find there mark!;)
got 130gr barnes in a dirty 30 going over 4340fps:yaeh am not durnk:
a 110gr barnes would go faster dont think anthing else would like a push up the bum that much
Rum ? Shot anything with them goin that fast and did the petals break off?Quote:

hey you forgot the .17,s
You cant beat the .223 for an all rounder, cheap to run and is good for rabbits, hares, magpies, goats and maybe even fallow.
308!!
