Smoothing a barrel with them other projectiles

[Thumbcocker]

I have a Bisley .45 colt . 45 acp that has had the cylinders reamed and shoots well. I still get leading along the base of one land. In desperation I purchased 100 of those other projectiles (250 Hornadays) and have loaded 50 over 17.5 of 2400.

Any thoughts on this load for smoothing up the last few spots inthe barrel? At .25 per projectile I don't want to do this a lot. Please don't judge me harshley I havent bougt factory ammo in years and this is only the second box of condomized handgun projectiles I have purchased since 1986.

I really don’t know the answer to your question but – I’ve had many rifles used both for various competitions and also hunting rifles that had match grade barrels and I broke them in by firing one shot and then cleaned out the copper. This took from 8 to 25 rounds to clean up the barrel, so it wouldn’t copper foul (not to improve accuracy).

I think this method would take some time at the range (maybe a week?) but firelapping with Veral Smith’s grit might be worth considering or maybe someone has a better idea that will post up.

My solution to similar problems with several 44 VAQUEROS has been to fire six rounds loaded with the RANCH DOG TLC 432 265 boolit with gas check and lubed with LEE Liquid Alox at the end of each shooting session. The guns with the lowest round count are showing improvement with each treatment. My other boolit designs use LARS' 50/50, 2500 or B-A-C lubes. I am a great fan of mid-range loads in the area of 1000 feet per second for 357 and 44 pistols....currently using TITEGROUP or HP38.

I start all of my NEW rifles and handguns with 50-100 jacketed-bullet factory loads, in the belief that they 1) might smoothe out the bore a bit and 2) in the event there's a problem with a new gun pending, I want it to occur while firing factory ammo. That subtracts a lot of argument at warrantee repair time (I hope).

I read a article years ago by Terry Murbach and he suggested a mid range load for smoothing things up.

I had a mauser with a rusted barrel inside and bought some lapping compound from Midway, comes in 220, 320 and 600 grit. Used it on some old mil surplus rounds, after 15 at 220 the rust didnt look bad and the pitting was minimal, after 10 round of 320 it was looking good and after 10 rounds of 600 is almost looked new, bore was easy to clean after that.
I did clean it after each grit real good, saved what looked like junk.
You might want to try just the 600 to polish things up a little.
