Projectile entity is displayed incorrectly

If I set projectile power greater than 4:

Model projectile entity:
 

public class ModelBulletEntity_Model<T extends Entity> extends EntityModel<T> {

        this.bb_main = root.getChild("bb_main");

        MeshDefinition meshdefinition = new MeshDefinition();
        PartDefinition partdefinition = meshdefinition.getRoot();

Renger projectile entity:

        poseStack.pushPose();
        poseStack.mulPose(Vector3f.YP.rotationDegrees(Mth.lerp(partialTicks, entityIn.yRotO, entityIn.getYRot()) - 90));
        poseStack.mulPose(Vector3f.ZP.rotationDegrees(90 + Mth.lerp(partialTicks, entityIn.xRotO, entityIn.getXRot())));
        model.renderToBuffer(poseStack, vb, packedLightIn, OverlayTexture.NO_OVERLAY, 1, 1, 1, 0.0625f);

if nothing can be done about it, perhaps there is a way to slow down the fall of the projectile? He falls too fast with little power
