PSB2 powder

I'm after some of the above, I'm in Suffolk. Happy to drive out to collect tho, within reason.

Or if you know an rfd with any?

make sure you got the right data though as not all PSB2 are the same

 

You got old PSB2 & PSB2 Special and the new PSB +2 & PSB+2 Special

 

the PSB2 SP is the slowest, the PSB2; then PSB+2 SP and finally the PSB+2

 

There is quite a difference in terms of pressure between the slowest PSB2 SP and the quicker PSB+2 so, be carefull as you can get 100-150 bar more than you expect just by using the same recipes.

 

For those who'd say there's no difference they're all the same (and there's plenty here)

 

This load was tested in December:

12/76/16 CX2000 2,10g x 44g B&P Z2M18 closed at 64mm

407 m/s

955 bar

Previously tested returned the following:

12/76/16 CX2000 2,10g x 44g B&P GT18 closed at 64mm

410 m/s

836 bar

Been using the data Clay and Game sent me with all the wads etc, works well in 32g #6 and so far so good with 36g #5.

Need to make up some more but running out!!!

I would always confirm with Steven what batch they tested .... some of the loads refer to M92S powder which is no been available in the market for quite few years now.

 

Also, some of the A1 loads tested seem to refer to old batches of (more progressive) A1 or at least have been available for the past 6-7 years (I bought their sheets in 2010 and, again last year) ... which is quite a long time for an everchangoing powder like A1

 

Not questioning the performances mind ya...
