CCI 350's vs WLP, how big of a diffrence?

[gofastman]

Id like to try to get a 200gr XTP or Beartooth WFNGC lead bullet moving at or around that magical 1200fps mark.

I also like to not blow my gun up.

this is a post from GlockTalk from the owner of doubletap

Here is some info from my work with Longshot. Always start 1.0gr lower and work up in .2gr increments until you see pressure signs. (Waters' method):
Starline Brass, CCI 350 primers, 1.26" OAL. 10 shot avg. G20 85F and 5000ft elevation.

135gr Nosler 13.2gr LS - 1542fps
165 GSHP 10.4gr LS - 1356fps
180 GSHP 9.6gr LS - 1294fps
200 XTP 8.2gr LS - 1172fps

These are loads that I have worked up to and are under 37,500psi when I had them tested. I hope this helps!

I have Longshot and WLP's, is there a big difference between them and CCI350's?
