Nickel pointed projectiles

I enjoy using both my BSA (1908) and Lithgow (1915) rifles to shoot targets. I refuse to use military ammo in my rifles, so I enjoy pulling the 174gn military projectiles out of old loaded military ammo and reloading these bullets into commercial cases. I have acquired a few Nickel jacketed pointed (not round nose) 174grain bullets which I am not familiar with. Their shape is exactly the same as the conventional military ammo except for the crimping groove which is substantially lower to the base of the projectile.

I would like to load these projectiles however I have concerns as to how I will remove the nickel fouling from the bores of my rifles after I have fired them. With copper jacketed bullets I use an ammonium based bore cleaner (Sweets 7.62 ). Can anyone advise how to remove the nickel from the bores? or whether I am best not to use them as the bores in both my rifles are in perfect condition.

Mottie's Paste?

.........or it's current equivalent, JB paste.

Prior to 1943 all British and Commonwealth .303 inch Ball Mark VII had cupro-nickel envelopes. After that date most were either gilding metal or gilding metal clad steel to conserve nickel, a far more strategic material.

Similarly, prior to 1944 the bullets were secured in the case by the three slit crimps which required the cannelure to be low on the bullet. After that date neck coning was introduced which required the cannelure in the higher position. I suspect you are used to seeing post WW2 ammunition with gilding metal envalopes and the high cannelure.
