Why does minecraft lags?

i downloaded a minecraft mod called SDK GUN MOD. i downloaded and i can see the guns since i have TOO MANY ITEMS. but for some reason whenever i use the gun it lags so much. the game only lags when i put the bullets in the gun. it doesnt lag when i have a gun with no bullets though. i can drive the ATVs with no problem and throw grenades too. snipers lag but when i use the scope it doesnt lag anymore. please help me. i really like this mod and i dont want to give it up. thanks

How does the c keyword "extern" work ?

What is wrong with my Xbox Account?

My Gold account recently expired. When I try to renew it on the XBL market place it says "Status Status Code: 80190864." I then went on xbox.com and payed for it there without an issue. But I go on my xbox and it still says I'm a free member. What is wrong and how do I fix it? Preferably without having to call microsoft. Any advice helps. Thanks.

How many people want to become Navy SEALs and how many will even make it to BUD/S training?
