.375 Raptor Recipe

I don't think you can run Lil'Gun for supers. It's probably too fast.

I was thinking that may be the case. Thanks for the input.

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.

Using Quickload has a learning curve as well.

Somebody correct me if I'm wrong but shouldn't 358 Rem data be a good start for 200 - 250 grain supers?

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.

 

[JR1200W3]

Ya, sorry. WIN.

That's why I stopped using Quick Load. It was too much to keep up with the backwards technology.

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.
