CFEBLK might work, but I haven't tested it yet. I use cfeblk with my 230gr VLR4s, but those are a solid copper drive band design. I'm not sure how it compares to the 235gr speer.
Reloder 10x and accurate 2200 are some powders to consider if your willing to grab another powder. I'm currently testing some powders between 10x and cfeblk. They are n130 and lt32.
1680 is probably as fast as I would go in lightweight (less than 200gr) supers.
I've been reloading for a few years now, but haven't ventured into the realm of experimenting with alternate powders. Are there any resources to keep things in the realm of sanity? I see 2200 is only two steps away from CFE BLK. I might give that a shot. I use XBR8208 for my 6.5 cartridges, but that appears a bit too slow.
8208 should be good for supers. Very similar burn rate as Xterminator and a long time decent 308 powder.
As far as existing resources 375 Raptor is a dark hole. People don't seem to want to share their load data and there's not a lot of people shooting it. Black Collar Arms says their close to selling loaded ammo, but show me their online data. I think they still have the original Raptor page linked which is now a dead website. I can send you the original Raptor site data but it's also pretty sparse. Your best bet would be to just pay for quick load. When I tried Lil Gun I just approximated off my 338 Spectre data. Which I had to pull out of thin air when I started with that powder and cartridge. Load a little less than I thought I needed, load one round at a time, gun mounted on tripod with Xero tracking, aim at a good backstop, turn head away from action and pull the trigger, lol. From there, if you still have a face, work up.
Lol. I've been envisioning that testing methodology the last few days! I was really hoping to avoid it!
Quick load huh? I'll have to check that out. Ive heard of it here, but decided to try GRT. Im sure over time i'd figure out what the heck i was doing, but its worth checking out your recommendation.
I believe I've found a few links to that original load data along woth a few others throughout this site.
Thank you for the info.

Can't find anything on 358 Rem. 358 win perhaps? Hard to believe you can't get a download of Quickload. I'll have to rummage around my PC parts bin to see if I have an external CD drive.

So now you just wing it based on experience? Well, that and apply the look away principles?
seems like a rough learning curve to get from simple reloader to experienced ammo creator.Ya, the only responsible thing I should tell you is use established load data or Quickload. But it doesn't leave you with much. I'll tell you what. I'll try some 8208 and report back the charges and velocity for you.So now you just wing it based on experience?

That would be greatly appreciated, but don't waste your time and resources on it unless there is some interest on your end as well. I'm guessing my raptor is still a month or two out. Dies and other reloading components should be here within a week or so.
10" barrel, 8208, 235gr Speer Hot Cor at 2.630"
43gr 2000fps
44gr 2038fps
45gr 2081fps
45.5gr 2114fps lightly compressed * only 1rd fired
46gr gr did not shoot, heavily compressed
By comparison I was getting between 2000fps and 2100 with Xterminator from 43 -47gr

Nice starting point for sure. Thank you for taking some time testing and sharing it! Mind me asking what you are sending those freedom seeds down range with? 10" AR platform?
I'm a bit surprised to see 2000 ft/lbs. Thought the raptor would have
more energy
Suppressed Weapon Systems integrally suppressed barrel. 10" of rifling, 10" of baffles.
That thing is sweet. Guessing damn quiet with subs? I'm guessing a 12.5" barrel might bump it up another 50 fps, but still not very energetic.
TBH, It's actually loud as hell. I'm very surprised at how poorly it performs. With supers I can see yellow in my scope during recoil from the fireball that comes out. I'm trying to figure out some way to sell it. I think this cartridge needs to be minimum 16" barrel based on how much powder burn is happening.
I'm having the same issue with the Lee dies and a Sinclair .375 mandrel. I get a little under .001" neck tension with either the expander ball or the mandrel. I'm going to have to turn down the mandrel. Using converted 308 Lake City brass.
Sheesh. Not expected at all. Faster powder maybe to get it all combusted by the time it reaches the end? Fireball means unspent powder. No? Have you tried the raptor recipes at 375raptor? Cant recall the grains, but they were using 40ish grains of 1200r to allegedly push 235s to 2400.
I've only tried Xterminator and 8208. 45 grains of powder is a normal 308W charge. Not surprising shooting it out of a 10" barrel sends a lot of still burning powder into the suppressor and even out of the suppressor. But it's the subsonic noise that's most disappointing to me. Loudest subs I've ever heard. I think 10" of a 1.2" suppressor doesn't suppress real well
I just got it last month. I would hunt whitetail with it but there really aren't any WT where I'm at right now
How does the muzzle speed out of it compare to quickload? Maybe 1200R would get it up to the marketed speeds? Not that it's going to help the report any. Once I get the 230s running I'm going to try some 350s. Probably the hornady CX line. Suppressed of course.
