How do I hit my sand, gap, and lob wedge further?

I’m 15 and a 5 handicap at my CC. I hit my sand wedge 85 yards and used to hit it 100 a couple months ago. My friend noticed that either my club at address is too open, or my swing is adding too much loft to my short irons and wedges. How do I hit my wedges further?

What degree of sand wedge should I use when I am facing a bunker beside the green?

I want to ask which club should I choose when I am facing a bunker near the green, because when I am playing 18 holes, I always hit my shot to the bunker and I feel very hard to get the ball up to the green and I saw lots of Pros hitting the bunker shot and control them very well , so please tell me what degree of sand wedge should I use(56 or 60 degree) an how to hit the shot better?

How to hit a 56 degree sand wedge?

I have always had problems withing my wedges, and I was just wondering if anyone had some advice on how to hit a good sand wedge shot. Stance, where to hit the ball, where the ball is in the stance, things like that.

Is it OK to use a sand wedge to practice short putting game?

Or is the sand wedge only for the sand bunker?
I wanna use the sand wedge when i am 20 feet away from the hole is this normal?
It is a plain green turf fast surface with no thick grass.

How do you hit a bunker shot? Also which is harder… when the sand is really wet/hard or really dry/beachy?

I just couldn’t hit a bunker shot today to save my life!! It was really really wet. I always try to slide the club under the ball which sometimes works but today i was hitting nothing but skulls.

Also has anyone ever from the bunker, when you don’t need alot of lift to get out just trying a chip like shot(no wrists)? i managed to do that today and i was pretty proud of it. lol

Why should you hit the sand first when hitting a bunker shot?

I play golf sometimes and I have read in all of these books and on youtube that you should be hitting the sand before the ball for a good bunker shot.

But whenever I am in a bunker, my ball just sits on top of the sand (bacuse my ball generally rolls into the bunker), I just go for a normal hit like on the fairway and the ball turns out how I wanted it weather its on the fairway or a metre from the cup.

Is it different when the ball is just sitting on the sand like my ball does? When I do it the way I do it, there is just a little mark in the sand and then it saves time on racking.

So am I doing the wrong thing and if I am…why?….and I am doing OK from a bunker.
