Sherman Wildcat Reloading Data is Here!!!

I have put together data from the many shooters that emailed/PM'd me. Here is what I have so far but I am still asking for more data to be PM'd to me so I can continue to add to this.
Thanks to everyone who contributed to this.
As always this data is for specific rifles and should be worked up to find what is safe in your rifle.
How do I get a copy or download? Can you send it to me Trecker?

@X'n Tex'n n555 is amazing in my 300 mega with a 208 eldm. I am extremely impressed with the n555 and have switched a couple rifles over to it. Probably going to order another 16 pounds of it.
I settled on N550 after trying both 550 and 555 in this last phase of tests. My goal was 2700mv in my 300 Mega, 18" barrel, with 208 LRHT's. I'm at 2730 with good sd/es. Shot at 600 yards yesterday, .370 moa, off of bipod, prone.

N555 does show promise, and I like the way it fills the case, but for my setup N550 had more consistent 4-shot groups in a six string ladder test, per each powder.
 
Hey all. What barrel length and chamber freebore would I need to get a 160cx going 3000fps or more with the 7ss cartridge? Thanks!

You can probably do it with a 24" barrel, possibly even a 22". I would go with the "long action" reamer, assuming that mono bullet is long. I run 180 hybrids.
I would try h4350, n550, n555 powders. Maybe even 4831sc. I don't remember the specs on my reamer. I'll check the f.b. and let u know

Last one I did was a short action Apollo lite with a 22inch benchmark... h4350 and 162 hornady bullets was mid 2900s
