Re: Transient Redneck Zombie Hitman
I've only had one rifle that had a really smooth bore when new (CZ 527 Kevlar Varmint). All the others benefitted from polishing the bore. I use Remington 40-X for finish polishing and occasional bore cleaning, particularly for copper fouling. I don't use chemicals for copper removal, as a mild abrasive is safer (at least for me, it's low toxicity stuff). JB bore paste is used for a really rough bore. Used rifles generally need a going over with JB, as do cheap new rifles like my Hi Point carbine. Very, very rough bore on that one.
Abrasive cleaners only remove copper and carbon above the level of rough metal surfaces. You want carbon filling the pits in the metal bore, if possible. Copper does not stick to carbon. A bore that is too smooth also copper fouls fast and accuracy quickly deteriorates. I only use M-Pro 7 for carbon removal, which is also Hoppe's Elite. Same stuff, made by Pantheon Chemical. Nontoxic and odorless. Nothing works better on carbon fouling.
No use working up accurate loads until the barrel is smoothed out on a new gun and copper fouling rate levels off at a moderate to low level. A load that groups the best on a rough new barrel is unlikely to shoot the same after break-in. I have an FAL that shoots sub MOA with Nosler Ballistic Tips at 200 yards. Average group is 1.8", down from about 8 inches with FNM military ball ammo. Installing the Austrian STG 58 bipod made the groups go that large, approximately double what it had been. 150 grain Ballistic Tips got the groups to about 3" at 200 yards, and installing a Limbsaver X-ring deresonator just in front of the sling swivel dropped the groups to 1.8" at 200 yards. Accurate enough for my intended hunting use.
FWIW, I often find that Nosler BT's shoot better than match ammo in my guns. That's because it IS match ammo that was hardened up a bit for hunting.....at long range. Way too soft a bullet for close-in woods hunting and big tough game. The 170 grain round nosed Partition is what you need there.
I find Nosler accurate across their entire line in .224 and .308, and an Accubond and Ballistic Tip will have the same point of impact at the same caliber and weight. If you hunt various animals at various distances in a single hunt, you will need more than one bullet. I will carry Accubonds with me next time, and Partitions for the in-your-face shots. One accurate load is not enough.
My latest Partition load: 60-grain PT, 23.5 grains Ramshot TAC, LC brass (weighed and matched), CCI primer. Sub MOA in the CZ 527, 9" twist in .223 Rem. Exterminator powder would probably work as well. Those 2 powders throw spot-on loads every time. Reloading goes fast that way. PT does not match AB or BT in POI at long range, but it don't matter as you save it for closer shots.
I'm planning to change over to .223 Rem for antelope and deer hunting (eating size, not trophy size deer). We'll see how the Scirocco II bullets do in the CZ 527 at long range. I can get a custom .224 Clark at a really good price right now, if somebody would buy my Colt AR-15 upper I have for sale. With a BC of around .500 at my altitude, the Scirocco should be a good performer in a .224 Clark.
Good luck with your new rifle.
