M224 Mortar restricted firing range

[Diver_ 0]

I am currently working on implementing a M224 mortar into game, I have all the basics working, rotation, elevation, rounds firing in the correct direction and all splashing within about 50m, when using the artillery computer it shows 450m > 499m. Can anyone suggest what is causing this narrow range and how to rectify it, this is currently what I have https://www.youtube.com/watch?v=dmUCX2n2MOE

 

The current config I have is simply there for me to get the model in game to test and is inheriting from B_Mortar_01_F as I know that currently works

class cfgVehicles {
	class B_Mortar_01_F;
 
	class 506th_weap_m224mortar : B_Mortar_01_F {
		scope = 2;
		displayname = "M224 60mm Mortar";
 
		model = "\506th_weap_m224\models\506th_m224_mortar.p3d";
		hiddenSelectionsTextures[] = { "506th_weap_m224\data\mortar\mortar_co.paa" };
	};
}

model.cfg

class cfgSkeletons
{
	class mortar
	{
		skeletonInherit = "";
		isDiscrete = 1;
		SkeletonBones[]=
		{
			"octovez", "",
			"bank", "octovez",
			"otochlaven", "bank"
		};
	};
};
class CfgModels
{
	class Default
	{
		sections[] = {};
		sectionsInherit="";
		skeletonName = "";
	};
	class 506th_m224_mortar : Default
	{
		skeletonName="mortar";
		sections[]=
		{
			"camo"
		};
		class Animations
		{
			class mainturret
			{
				type="rotationY";
				source="mainturret";
				selection="octovez";
				axis="otocvez_axis";
				minValue = -6.2831855;
				maxValue = 6.2831855;
				angle0 = -6.2831855;
				angle1 = 6.2831855;
				animPeriod = 0.0;
				initPhase = 0.0;
			};
			class maingun
			{
				type="rotationX";
				source="maingun";
				selection="bank";
				axis="otochlaven_axis";
				minValue = -6.2831855;
				maxValue = 6.2831855;
				angle0 = -6.2831855;
				angle1 = 6.2831855;
				animPeriod = 0.0;
				initPhase = 0.0;
			};
		};
	};
};

 

 

When I use the Virtual Arsenal I can use the projectile tracking lines to see what the rounds are doing,

By the way the rounds are going and based on the basic config I have used I am guessing that it is something wrong with the model. If there is anyone who is able to help it would be greatly appreciated
