Just borescoped my 338 MRAD barrel. Its after 70 shots. What do you think what these discolorations are? It looks like copper , but i ve never shot any copper or red brass cardridges. I only shot Nickel plated bullets. RWS speed tip pro.
Is this fouling or a barrel discoloration from heat? Can i clean this? With shooters choice or Eliminator it didnt work.
And what do you think about the barrel condition?
One of my friend shot few box with Norma ECO, that use this same king of nicke plating in the bullets.
Hi did not need to shoot even 3 20-round box when the accuracy was totally losted, i mean that this Blaser did shoot 1/2 MOA group before, but after about 50 shot with this ammo, it was totally useles.
Nothing else but these nicklel plated ammo was causing the dilemma.
That freaking nickel is in the barrel like a shit in the wall.
We had to to do a lot of work that we get that nickel out of the barrel, bronze brush and all kind of cobber removers, nothing.
One of my friend told us that only nitric acid will remove that nickel on the barrel.
So we had to took the barrel out of the rifle, put a cap on to other end, fill the barrel with nitric acid and put cap to the chamber.
That nitric acid was in side in the barrel about 1 hour.
After that we did made long cleaning rod with the carbon fibre bow arrow, epoxy glued nylon brush on that and we did wind the barrel with electric drill machine, and dropping CLP in to the barrel for a while.
It took about an hour to make that barrel enough clean that the nickel out of the bore.
So i would NOT recomend to shoot with the nickel plated ammo for all the time.
Like this ammo of RWS is more hunting ammo, that range cartridge, if you ask me, i would not use it any where than in the hunting, and that goes every nickel plated ammo.
