will take over R148

Welcome to CRUS firejuggler. If you have any questions about sieving or testing, let us know. Can I ask what range you plan to sieve and test and how many cores can you dedicate to it? 7 k's at n=120K for such a high base is a lot of work. One modern quadcore running all 4 cores 24x7 should be enough but progress will still be slow. 
S249 is complete to n=100K; 2 primes were found for n=50K100K shown below; 8 k's remain; base released.
Primes: 286*249^52498+1 754*249^54387+1 
in the beginning i was planning to do 120200k, on a core 2 duo... upon sieving /llr'ing i'll do it up to 130k only.

ok, back to reality . i won't be able to do this. releasing b148...
find k=1256 sieved up to 1.13e12 and the other k sieved up to 67.5e9 sorry again. (n 120k130k) 
Reserving S166 to n=25K (recommended base). Rough time estimate is 2 weeks.

Reserving S171 and S211 to n=100K.
