I am using the 5 oz priming sugar per 5 gallons it is carbed up but I wish it had a little more. I though that maybe the caps weren't that tight but I rechecked them all and I am using the red wing capper. I was thinking of maybe going to 5.5 or 6 oz priming sugar or would I be risking bottle bombs
That wouldn't hurt. What style are we talking? Some brews will benefit from a good bit more or less priming sugar. Also, the temp of your beer at bottling will have an impact as well... Cold liquid will hold more dissolved co2 in solution.
The bottles have been at room temp for around 7 weeks I put 6 of them in the fridge yesterday I have been drinking a few for the last 4 weeks. I made a kind of Samuel Adams clone extract kit. It fermented for 4 weeks and was around 70 when I bottled.
Yup all of the above and how long did you leave it at room temp it takes a light beer 2 or 3 weeks to carb up and a higher gravity beer months I am told.
1 oz per gallon is pretty common and for me it puts me up to 2.7 gravities if I bottle at 70 degrees.
Depending on your bottles I would not go much higher than that. Some bottles are much heavier and can hold greater pressures but I was told from the brewery where i bought the bottles to never go over 3 atmospheres or I would risk bottle bombs.
And to be honest to my taste 2.7 is about right for me. It falls in line with the bud and coors crowd.
Then it could be that:
1) You don't care for that volume of carb
2) You actually had more than 5 gallons when you bottled
3) Your priming solution didn't mix well enough and some bottles will be under/over carbed
