How can I improve my starter bow set?

What kind of hunting are you doing?

Do you plan to shoot something greater than 40 yards?

You're not losing much with the whisker biscuit

I used a single pin HHA for about 10 years. You can get them on Ebay for pretty cheap. Their customer service is great. I bought mine used. I contacted them about a problem with the rheostat and they told me if I sent it to them they'd go over it, clean it, etc free of charge before I started hunting with it. They also sent me another rheostat for free when they knew I'd bought the sight off of ebay. Awesome customer service.

I try not to shoot over 30 yards (at deer) so I'd just set the pin at 25 and rarely had to move it while hunting. I completely freak the F out when a deer is under me so it helped not having to choose a pin. Doesn't matter how much I practice. I'm automatically 10x more retarded when a deer is in bow range.

If you haven't already, I would take to your local archery pro shop and make sure the bow is tuned correctly, and that you're shooting the correct spine and length arrows for your draw length/weight.

Seems obvious but those things really do make a big difference. But of course shooting technique is by far most important

Man, if you're shooting accurately with the set up you have now, don't change anything. Seriously.

Post pic of arrow group. I shoot a biscuit. I kill deer with it.

Where are you guys going to get bows tuned? Ive got one that I set up myself, so I know it needs to be tuned.

What kind of arrows do you have? Are they all the same length spine and weight? That would be a good investment with some of your $400.

In order of bang for the buck(these things will make a larger accuracy improvement than an actual equipment upgrade)
-at least 6 arrows that match and are the proper spine
-a peep sight that is the right diameter to match your sight housing
-a peep sight that is the perfect comfortable height
-the right draw length, if this is adjustable get it dialed in

Then I would upgrade some equipment
-a sight with an adjustable 1st-3rd axis will make you more accurate if leveled
-if you are looking at getting a sliding sight to shoot further, I’d probably get rid of the biscuit. I generally recommend QAD rests and Montana black gold multi pin sliders.

Lots of different ways to go about this.

If your goal is to hunt whitetail and shoot targets out to 40 yards your set up is perfectly fine.

I would agree in general with what’s said above.

Make sure draw length is correct.

Make sure string is in good shape.

Check arrow length/spine.

Pick a solid consistent arrow from a good manufacturer. (Easton Axis is a safe bet and has been around forever) .

Paper tune, bareshaft tune.

Get some decent broadheads that fly well and broadhead tune your bow.

Bonus: Check out Joel Turner’s podcast on Kifarucast to develop a solid shot sequence.

If you want to shoot longer distances than 40 and really want to dive in to archery, my advice would be to not spend the money on new sights or rests. I would save your money and consider working towards a new top end bow over the next couple of years.

Join archerytalk and join in on some discussions. Once you get 20 or so post you can see the classifieds forum. You can typically find whatever your looking for in great shape and half the price or less. If your accurate with that biscuit i would look into a new sight. Probably be some really good spot hoggs hit the classifieds soon being they are about to start shipping their new boonie sight.
