Ive been using the montana xtreme blackhorn solvent and bore conditioner since switching to Blackhorn powder when it first came out.
With my gun (CVA Optima) about 5 shots is max then needs cleaned. If im target shooting and want to shoot more just wet patch and a couple dry patches.
If im cleaning to load for hunting after a shooting session . I go wet patch , brush and repeat until clean , usually 2-3 times .Then dry patches 2-3 , then bore conditioner and a couple dry patches after.
Seems to work really well . Although unless something changes with Blackhorn powder and now these cleaning products I will probably find a different avenue ,after I use up what I have . The montana xtreme cleaning products have seemed to double in price just like the powder....But thats neither here nor there ..lol
