A friend called the other day and said he just got a new Lyman bore scope. It was on sale at Midway, and he had some coupon code plus Midway offered free shipping for orders over???. He got the scope for a pittance.
He called today and said I should bring my lever gun and some other rifles down and let him check them out. The Mossberg gave me fits and I did not know if I had a bad rifle, bad mounts, scope or what the heck was the matter but I could not keep bullets on the paper at 50 yards.
Someone told me about J-B bore compound from Brownell's so I ordered some via Amazon. Even the price was a few dollars more than anywhere else I still paid less because I am a Prime member. Believe me, if you order as many times a year as I do it pays to have Prime.
I scrubbed the bore with Hoppe's, Ballistol and Sweets and still, when I used a Kleen Bore patch the patch still came out tarry black. (Then I found out it would always come out black because of the polish. DUH!) But the rifle shot many times better than before.
It was loaded with factory grease and I did not get it all when I cleaned it the first, second or third time. I did not know factory grease turned to something similar to epoxy that is about 5 minutes from being totally cured. It had to be pried out with q tips and a lot of oil soaking. I had to disassemble the rifle to get it all but the extra effort was worth it.
I then Kroiled the bore, smeared some J-B on a patch, many patches, and ran them in and out 10 times each. The patches also turned black. J-B patches also always turn black and about 10 ups and 10 strokes down the bore will blacken the paste so I surmised it was time to change patches.
I used brushes when the patch holder tips failed to hold the patches and it worked great.Eventually I got the 50 ins and outs finished and ran in some more wet Kroil patches to flush out the J-B, dried with some clean patches and then used Hoppe's to see if there was anything left to scrub out. Patches came out a bit grayed but no marks specific to dirty rifling. Just a soiled gray patch. Job done.
My friend scoped the 464 and also my Savage .308 that I spent a few extra minutes on with the J-B and he said both bores were absolutely, perfectly clean. There were some marks in the rifling in both bores and there were scratches in the chamber of the 464. But, I know how well the .308 shot last time, and I also saw a huge improvement when I shot the 464 the other day. It responded very well after a good cleaning but I am sure it will be even better now after getting all the fouling and factory glop out of the bore.
I have now J-B'd my MVP 5.56, Savage 11 V/T .308, Mossberg 464 30-30 and Savage MKII FV.22. Next in line...Marlin Model 60, 3 BP rifles, a Silent Cat .177 Spring Air rifle, and whatever else I feel like pumping a bronze brush and patches through.
I am sold on J-B and now I know how to clean a rifle barrel. I have always been (I thought) thorough but the Mossberg 30-30 showed me differently. I won't be lax again.
I was getting first shot fliers. I swabbed the bore every 5th shot and allowed the barrel to cool. All the targets show 1 shot severely low and left. After the first shot the next 4 or 9 were better. But, I did not swab between shot 5 and shot 6-10 (target 3) To me this illustrated cold bore first shot flyers.
These 3 targets are the last 3 after sighting in. I hope to have even better targets to post after a trip to the range.
If I already posted these targets OOPS! Sorry.
Targets were at 50 yards. All rounds were home growns. I have not tested any of these rounds and the ammo was loaded 2 1/2 years ago when I had my 336. Load data: OAL 2.550"; Sierra FNSP 150 gr; Fed LR Primer; R-P cases; Powder: 37.5 gr Hodgdon Leverevolution. I used the back of my hand between thumb and forefinger, set on a Gorilla Bag. The bench was set up kind of weird and it was all tore up by a-holes who love to destroy. But it was available and I wanted to shoot. I tried a rear rest but there was just no room on the bench.
I shot 10 sight in shots and 3, 5 shot groups for "score". This is the most consistent I shot since getting the rifle. I am posting the targets to show my progress. I expect even more improvement after polishing the bore and getting ALL the factory grease and preservative out of the action and bore.
Target 1 is a 3” orange stick on spot. Target 2 is a black 2” spot. Target 3 is a 7” target with a ¾” red spot. The 10 ring is 2 ½”
