A couple of suggestions:
• suggest you use bronze core brushes rather than steel cored. Steel cores can damage your rifling.
• Also, didn't see one, but if you don't have one, get a bore guide to keep the rod and tip straight in the barrel.
• Recommend a bore specific pierce type jag to push patches. They do a far superior job to loops.
You can get non-brass jags so you don't get false positives on copper (blue patches)
Good luck on your journey in school and at the range!
That was actually @VLD Pilot who said he bought one from Amazon, but I did just order one as well. Anyways, here are the links.Archangel. You got a link for what you bought off Amazon? Thanks!
I have a Left handed Savage in 17 HMR. Every time I clean it my groups open up to 1” to 1.5” at 100 yards. After 30 to 50 rounds it settles down to Sub MOA again. It’s happened to me three different times now.Jon, Clean rifles do not shoot worse. I Have had Savages whose barrels looked like a Sewer pipe. These rifles would shoot like this:
7 Mag- Model 116 would shoot 3/8" groups for 9 rounds from a clean barrel. Then go to 3/4" for about 9 shots, then 1.5"-2" for around the next 40 shots, then 3" from there on.
30/06, 270's would shoot around 3/4", then go to 1.5-1.750" groups
Some BAR's and 7400's were the same in 30/06 and 270.
I keep hearing about those barrels that shoot better after 20-40 rounds but no one in my immediate family has one, nor any of my shooting buddies and I have been shooting centerfires since 1967. I also shot a lot of benchrest comp and other disciplines.
We chalked up this Shooting better after 20-40 rounds to a guy that settles down and starts shooting better.
Rule of thumb is, if you want the best accuracy out of your rifle, then keep it clean. You do not know it is clean unless you own a bore scope. My hunting partner and I shot 20K rounds a year shooting p dogs, ground squirrels, and chucks. We did not own a bore scope for a while. As soon as we did get a medical device that we used as a bore scope, we learned certain powders are harder on barrels. We also learned how carbon builds up in front of the throat. We were shooting at times 1100-1200 rounds of centerfire a day on p. dog towns. We learned how to keep the barrels performing for the five gallon bucked of ammo we were going to shoot up per barrel on that trip....223, 22/250, 243, and 243 AI.
The fire-lapping is something guy either love or hate. A lot of guys are philosophically opposed to the idea of running anything abrasive through their rifle bore. I strongly suspect that most of the guys who hate it have either never tried it, or they didn't read the directions before they did it.First thing buy a borescope from Amazon.
Of your 300 is as rough as my 308 (which soots submoa as made) you may want to fire lap it.
I've cured several copper foulers with the kit sold on Amazon. Contrary to instructions, start with finest grit, lap clean and shoot to see how much it still fouls. You can always take more metal out but you can't put it back.
