H110 case space and seating depth

Postby Jaysin52 » Tue Oct 25, 2022 6:00 pm

Good evening everyone... I'm looking for some feedback from people with experience loading H110 powder. Specifically, seating depth and case volumes. I've been reloading for just over a year in about 7 different calibers (bottleneck, pistol, straight wall rifle) ... I understand that the longer seating depth gets you closer to the lands and should increase accuracy... but with the h110, allowing extra space in the case tends to lead to wider spreads on velocities, not necessarily accuracy problems. I've played around with 450 bushmaster and 350 legend trial and error on both. My findings are more consistent velocities seating deeper on both and also higher velocities. So where is the happy medium/sweet spot? Or, is there a given that I'm missing somewhere.

Thank you in advance.
Jason

What bullet and what gun? I load for an AR and the magazine limits the OAL that can be loaded and I have never had an AR chamber that I could even get close to the lands with a cartridge that will fit in the magazine.

I'm loading for a CVA Scout single shot and an AR... I know that I'm nowhere near the lands but was under the impression that the longer depth typically generates better accuracy. I'm loading the following:

225 gr FTX - 2.15 OAL
250 gr FTX - 2.23 OAL
260 gr Platinum Tip - 2.10 OAL
240 gr XTP - 2.15 OAL (cannelure depth)
245 gr SP - 2.15 OAL

Erik Cortina has some interesting takes on the subject of "chasing the lands".
