Collision Detection inconsistent ? Raycasting?

Unity Engine
1

I’m having trouble with the Raycasting collision detection,

I have created a prefab that casts a ray, and if it hits a wall it will instantiate a decal on the given hit.point

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using ThreeEyedGames;
using UnityEngine.Rendering;

public class Rob_Blood_Test : MonoBehaviour {

    // Use this for initialization
    public GameObject decalPrefab;
    public float raydistance = 0.5f;

    public Material[] bloodSplats;
    //public  Eas
    void Start ()
    {
        Destroy(this.gameObject,1.5f);
    }
   
    // Update is called once per frame
    void Update ()
    {

        LayerMask layerMask = (1 << 10 | 1 << 9);
        RaycastHit hit;
        if (Physics.Raycast(transform.position,transform.forward, out hit, raydistance, layerMask))
        {
            if (hit.collider.tag != "Enemy" && hit.collider.tag != "Player")
            {
                GameObject decal = Instantiate(decalPrefab, hit.collider.transform, true);
                decal.GetComponent<ThreeEyedGames.Decal>().Material = bloodSplats[Random.Range(0, bloodSplats.Length)];
                decal.transform.position = hit.point;
                decal.transform.up = hit.normal;
                decal.transform.Rotate(Vector3.up, Random.Range(0, 360), Space.Self);
                Destroy(this.gameObject);
            }

        }
        Debug.DrawRay(transform.position, transform.forward * raydistance, Color.green);

    }


    private void ChangeMaterialIndex()
    {
        if (bloodSplats.Length == 0) { return; }

        int i = Random.Range(0, bloodSplats.Length - 1);
        Material randomMat = bloodSplats[i];
    }

}

This works fine, until it is moving too fast using

                GameObject go = Instantiate(bloodSpawnTest, new Vector3(Random.Range(transform.position.x - 1.0f, transform.position.x + 1.0f),transform.position.y, Random.Range(transform.position.z - 1.0f, transform.position.z + 1.0f)), transform.rotation) as GameObject;
                go.GetComponent<Rigidbody>().AddForce(transform.forward * Random.Range(5,10), ForceMode.Impulse);

The Rigidbody is set to continuous Dynamic and it is still clipping through walls and only working 10% of the time,

Is there any other ways I can make the collision detection more reliable?

I know this is super old, but I just spent a long time figuring out that any kind of raycast to hit a collider attached to an object with a non-kinematic rigidbody AND A NAVMESH AGENT will return extremely inconsistent hits. The rigidbody should be kinematic in this case.
