Dumb question - is the photo with red line pre or post neck turn ?

Well Ive got a 22" barrel on mine so it would be nice to get close to that. Have you ever tried those 150gn Sciroccos?

Time for me to buy some Neck turning gear

No never used them. The 150 sgk and 150 NBT both seem to work well.

Re-testing those loads @2800 a 2nd time, I was getting the odd one with excess pressure. Backed it down a bit and retested.....

But I also tried H414........it likes it!

Here's the 6 shot ladder, last 3 were tight at the top.

Currently loading up more at 53gr to try at 300 and 400 yards.

Thanks for the post. I have had trouble with donuts (not at work aye Ginga) in my 284 brass and have been inside reaming the necks prior to resizing to take them out. Haven't measured the necks yet through but get the whole thicker base once necked up. Would you neck turn the fired brass before resizing or after through the FL die? Thanks, Jase

After FL sizing, you then trim them all to the same length before neck turning

Yeah you need to size them before running the expander mandrel thru them to get the necks to the perfect size to fit the mandrel on your turning tool.

Excellent. Thank you

Looking at this really makes one have a desire for a 284win!! Bloody well done!

Jasec, get your donuts sorted?

It's going pretty well now @Tahr. Quick test at 300 yards.
