in search of data?

[Ridge Runner]

I've been seeing a bunch of interest on this forum of guys searching for data, how do you think wildcatters find it? make your own in your own rifle then you have good accurate data, that you know is safe in your rifle. so here goes
(insert disclaimer here)
Do not attempt this if you don't know what signs of excessive pressure are!

Been alot of interest in the superformance powder, why I don't know but lets see how we go about getting a starting load for itok ya wanna start in the 30/06, ok lets say ya wanna use a 150 gr nosler BT.
check out the burn rate on hodgdons site, superformance is just slower than H4831, so go to the H4831 data for a 150 gr bullet, take the max load, cut it 5%, then cut it another 2% as a buffer for possible different bearing surfaces of the 150 gr bullet.
load a round in a new case and fire (this is where a chrony will help you alot but if you can read signs of pressure you can get by without it.)
if the first round goes well check the case over closely, lots of things to look at to determine if you running proper pressure.
1) primer is it flattened?
2) bolt lift, is it heavy?
3) extraction sticky?
4) is the round dirty after firing?
superformance is a ball powder so it will run dirty till your getting up close to max pressure.
if the load is safe, start bumping the charge up 0.1 gr. until you hit a pressure sign, back off that 1/2 gr and that is the max load for your rifle.
then if accuracy needs tweaked, back the max load off 1 full gr and start messing with seating depth,
pressures run higher with any given load the closer to the lands ya get, so keep that in mind.
Now another disclaimer all powders are tempature sensative, double base or ball powders are worse than single based powders, how do you know if its single or double based powder, all sperical or ball powders are double based, as is any powder that says it contains nitroglycerine.
don't work up a max load in the winter and expect it to work in the summer at 90°. I'll guarrantee you velocity will be higher, with ball powders alot higher.
An example, In my long range specialty rig which I shoot ball powder in, in normal deer hunting weather, it runs a 160 gr nosler downrange at 3575 fps, no heavy bolt, no sticky extraction, just a good all around load, thats just a lil bit sooty so I know I'm pushin around 55K psi, at 90°, the load burns clean as a pin, heavy bolt lift, very hard extraction and if ya chrony it, its above 3750 fps. this is extreme but it can happen.
just be careful, make good notes and pay attention, its not that hard, and its better than getting data off a forum, you'll know yours is proven.

edited to add: I don't understand why everyone thinks they gotta shoot the max loads, ran some numbers with a proven trajectory for my 6.5 gibbs
this rifle runs a 140 berger at 3150 fps, its a very good shooting rifle that I use for deer hunting and varmints out to 1100 yards
at 3150 sighted in at 200 yards its 9.1" low at 350 yards
bump it up to 3300 with the same sight-in, its -8.2" at 350 yards
accuracy isn't as good (it never is at max pressure)
cases last 1/2 as long
and barrel wear occurs at 5x the normal rate
and your using 3% more powder for a .04% increase in MV, the point of diminishing returns.
