Part two: 
 I've now got a little more shooting done with this rifle. I have shot it in two matches and finally got some chrono info.  
The first match (3/26) wasn't horrible but, it wasn't very competitive with a 235 1c (ASSRA). It was about what you can expect with a target rifle, shooting standard velocity, fixed, domestic ammo.  
Saturdays match (4/23) was much better. It shot all 24's and 25's but, had one score killing 22. The March score had five 23's in it. My April, ASSRA score was 242 4c and it scored 244 6c, ISSA.   
The conditions were tricky today and there were three 245 5c (ISSA) shot with some of the most competitive 22 RF rifles, on the West coast!   
I'm a big dissenter regard ISSA scoring. ISSA had their reasons for doing it that way (leaded edge) but, it really doesn't give a accurate score. I tried to re-instate ASSRA scoring at our club but, was out voted at this match.   
Now the best part of the match was, scored ASSRA I would have had, 242 4c, second place (third ISSA) was 241 3c and first place ISSA would have scored only 240 3c.  
So, now, I'm off to a good basic starting point 
 
  Next month, I will have much more info, regarding how it scores. I'll be shooting a 240 shot  22 RF match.  
As it stands, B'Eye is still the most accurate powder. The 14 twist is a little slow for my .56 long, 53 gr bullet. It doesn't tip at 1.7 gr but, shows a little tipping at 1.5 & 1.6.   
I used 1.6 gr in this last match and you can see some some slight tipping on some of the holes.  
The March match was shot with 1.5 gr. I'm not sure that the increased accuracy is a result of the 1.6 gr charge or, if it's because I sized the bullets from .225, to .223. I did that, because it was to hard to BS at .225. My groove is a standard 22 RF at .222.  
As I said, I'm only getting acceptable accuracy with B'Eye. Last Wed. I tested Ramshot Silhouette  and TiteGroup. Nothing near as good as B'Eye but, I found that I could get a ave  1329 fps with my 53 gr bullet, using 2.5 gr Silhouette.  
The B'Eye load that I chronographed was 1.7 gr. I used both CCI & Fiocchi cases with the following results:  
Fiocchi  
1.7 gr, Ave 1170 fps 
High 1183 
Low 1138 
ES 45 
SD 15.5 
Ave Divation 10.6  
CCI 
1.7 gr, Ave 1167 
High 1173 
Low 1151 
ES 43 
SD 13.5 
Ave D 10.6  
I only used the CCI cases at the match and those will be my standard cases.  
I want to keep these loads subsonic, like the match ammo is, for the added wind drift advantage, and that is why I choose the 1.6 gr load
