Load info for 230gr xtreme hp with Unique

[ReedyMod1]

I loaded up 10 of each at 5.6,5.8 and 6grs. All were set to 1.23 to 1.235. The 6 gr rounds looked like the primers were showing pressure. These were shot out of a Glock 21. Speer lists 6 grs as max seated at 1.20, Hornaday list 6.7grs as a max for the XTP seated at 1.23.

I know the length of the Extreme hp is .642 the length of the hornaday is .641 or .642 .The Speer is .650 or .670 in length. I thought i would be good at 6 grs just the thought of pressure and being like .7grs away from a max charge just has me thinking.

Could it be the oal at 1.23 to 1.235 with the shape of the bullet it is closer to the rifling bringing the pressure up.

Should I seat these deeper to 1.21 to 1.215,Anyone loading this bullet or anyone that can give me a direction on this would be a great help.

I do have 4 manuals just want to bounce it off some others that may have some time with this bullet.

I'm a newb to reloading but I just loaded up a batch of 230gr xtreme hp's using 4.6gr Red Dot with an OAL of 1.24 and a tight crimp. I was kinda surprised because they cycled my FNP45TAC flawlessly. I had read up on a bunch of people running max plus loads of tite group and figured I'd need to go heavy but 4.6gr did the trick and the OAL did'nt produce any feeding issues with the magazines. I cooked up 30 rds and test fired them at the range then I turned out the rest of the box of 500.
