Using Hornady 139sst and brass with federal ir primers over adi2206h 42.5 grn from memory
Getting 2900fps with es of 25fps
Not target loading but I'm still learning and I have found on bush hunting whitetail fallow Reds and sheep it's plenty good enough

That's a pretty hot load. RL17 or Superformance maybe but 2206H? My manual taps out at 41.6

Yes these and the 140 gn Sierra Prohunter flat bases.
Time might move on but these are timeless… priced ok (Sierras are dearer).

ADI website lists 42.5gr as max, as far as I can tell.

Typewriter.,.. shikes I'm still pen n paper type of guy. But I do see your point. Funny that fellas get flash Harry super slippery plastic tipped. Weighed to last tenth of grain seated to hairs width accurate loads then shoot deer at under 150 yards with them....more often than not.

Yes but from a 24" barrel giving 2857fps. If 2900fps is true and from an 18" barrel something doesn't add up. Either it's a chronograph cousin to Dundee's rangefinder or a magic barrel.

Maybe
Works for me
Each to there own
I wont take you calling me a liar personally
There maybe be fault in the gear as you say
You never know eh

I get around 2850 fps with a 140 and 43 of 2208. 21 inch tube. A similar amount of 2206h should have more pressure being a bit quicker powder. Warm for sure but 2900 is in the realm.

Sorry, I don't recall calling you a liar but I'm glad you're not upset anyway.
2 component manufacturers can't get the same speed as you but, you never know eh.

Could seating depth be a factor here? Book data is derived from Saami spec bullets isnt it? and if a bullet is seated close to the lands pressure spikes, same as if a bullet is seated deeper? More pressure generally equates to more velocity? Im no expert and not looking to poke sticks at anyone, just generally interested.

Could be but pressure is pressure no matter how you get it.

51 grains of staball 6.5 with win brass fed 210 primers and 139 interlocks gets me 2850 fps out of a 17 inch barrel according to the Labrador.
