Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_5324 ( "Bullet weight gram (grain)" text, "8.23 g (127 gr)" real, "9.72 g (150 gr)" real, "11.34 g (175 gr)" real, "12.96 g (200 gr)" real, "14.26 g (220 gr)" real, "Case capacity (%)" real )

### Question ###
Which 8.23 g (127 gr) has a Bullet weight gram (grain) of 8x64mm s, and a 12.96 g (200 gr) smaller than 102.9?

### Accurate SQL ###

SELECT AVG("8.23 g (127 gr)") FROM table_5324 WHERE "Bullet weight gram (grain)" = '8x64mm s' AND "12.96 g (200 gr)" < '102.9'
