Hi, just a dumb question.
A 150 grain pushed with 47.7 of 2208 out of a 20.25" tube will be going how fast please? Approx obviously. Will get in line for the chrony to validate.
Thanks. I think.

2800-2900fps
Thanks. In your humble opinion what would or could max speed be for said firearm? Is that about it? I have no pressure signs yet however I know it's a fine line. I need to chrony to verify anyway but just jumping ahead.
2860 fps
And the North Island forum crony is at my place at the moment, I'm just waiting for a new brain for it. Then it's available to whoever.
2900 is pushing pretty hard with 2208, not a brass life load.

Thanks both. Great.
I reconk 2750 from a 20" barrel so I will be interested in the chrono result.
Me too.
Any result on this?
Nothing on speeds. Need to chrony. Accuracy is NOW good with 150 Accubonds.Quote:

Where is that ni chrony ? I'd better look see.
I get an average of just slightly over 2,800 fps in a 20" .308 using 2206H and 150gr SST's. It's a very warm load but certainly not max. Case life is very good with Lapua brass.
Thanks mate.Quote:

I have got 51.6 of 2208 in behind Barnes, its a pain tho.

no it means they used a blend of powders for the caliber and projectile.Quote:

Acccuracy settled down during the shoot. No pressure signs.
130ttsx
50.4@2208=2850-2900fps. Too slow for me.
51gr 2208 fed magnum primer fed brass 130ttsx was 3000fps out of my old mans 18'' Rossi
51.6 3180 out of my Sako......pain to load tho drop tube and trickle it in.
H335 would be much better but I have lots of 2208:thumbsup:
Am out of 130 ttsx so for now will load and use these 150 and 160 Accubonds.
Thanks for that.
47.8.gr of 2208 is all I can get in a case (lapua) 50 in a federal with a 150 gameking on top, havnt cronied any but in my remington best accuracy came with 45.5g (1.3 inch 5 round groups at 100m) so now that's all I use. Havnt a clue about speed but am on the list for the crony, but it tips things over ok. I think speed can be overrated.
I am sure my scales are slightly out at times. I loaded 15 of 150AB with 47.7 of 2208 and that wasn't full, at all.
I have definitely noted (at times), different readings when I double check my loads.
These are with the Lyman Pro 500.
And yes Speed is def overrated especially with certain projectiles like the Gamekings. These Accubonds are apparently going at 2800+\-20fps so neither here nor there but is only my bush gun and with an eye forward to the roar.
These shoot well, that's the important thing...
I get 3,100fps with 130 TTSX - 49 gr 2206H, Fed 210M. Pretty warm load but comfortably safe in my rifle with 20" barrel.
Has anyone else chrono these? They shot @ 1.5" grouping at 240yards today out of my Sako 308. Only had three left so inconclusive.Quote:

Danny, if you need a chrony I have one here you can use. Could arrange a sortie to the Tok shooting complex which is only two minutes from my place.
True?... I'm over there each week with mahi. I'd be keen as.Quote:

Absolutely true. Send me a PM when you're over here, time etc and we'll take it from there.
I read in one of the mags that they chrony pretty close to what was stated on the pack (3000fps) Out of a Rem 700 24inch barrel they were going 2986 average. Im prob going to go to the 150sst with my Rem 308 after I use my Rem corelolts up as they group slightly betterQuote:
