ADI manual lists 27.5C AR2208 as max for 55gr bullet. For 3384fps

All rifles are different loading manuals are just starting places.

hand Loads always leave loading date for dead sometimes as much as 300 feet per second with no detrimental effects on brass depending on calibres

I think your looking at a different chambering. Note the COL is different.

My apologies I thought you were talking about 22 250

I dont have that rifle anymore, but yes i did chrono the 21gr load and it was right on 3100fps average. How much 2206H would send a 55gr down a 1:14 to get 3600fps? Would it even fit in the case?

Sorry, I didn't set that out very well and swapped from one bullet and referred to another. I was trying to say that your load of 2207 behind a 50 grain bullet would probably only get you to perhaps 3100 fps but by using 2206H or 2208, you could get yourself a ton of extra speed, up to 500 fps extra.

If you tried this slower powder with a 55 grain bullet, you may find that you get the speed and therefore the RPM needed to stabilise this slightly longer bullet. I don't know if 3,600 fps is possible from a 55 grain bullet, you may be over pressure before you get there and blowing primers. Always a bit of fun to try.

Lol. s**t happens. Also easy to get confused when looking at lines of data at anytime. (For me anyway)

Suggest you delete the images. I case a new reloader gets it wrong.

Just worked out where I stuffed up I was looking at the 223 and 22 250 thread so obviously this old bloke got a bit confused .

ADI lists max for a 55gn Speer softpoint as 26gn @ 3315fps with 2206H.

Using a 36gn Barnes Varmint Grenade you'll net 3755fps with 27.3gn of 2206H.

Results may vary. Proudly spoken and authorised by some bloke on the internet

Would never fitt in a 223 case.

Sorry, typo. And yeah 36gn has no way of fitting in.
