Unity shooting problems

Problem:My bullet just bounces off the wall every time I shoot and hit a wall,any fix? 
My code:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

public class BulletController : MonoBehaviour

{

    public float moveSpeed, lifeTime;

    public Rigidbody theRB;

    // Start is called before the first frame update

    void Update()

    {

        theRB.velocity = transform.forward * moveSpeed;

        lifeTime -= Time.deltaTime;

        if (lifeTime <= 0)

        {

            Destroy(gameObject);

        }

    }

    private void OnTriggerEnter(Collider other)

    {

        Destroy(gameObject);

        

    }

}

Walls are usually not triggers. Use OnCollisionEnter instead.
