I purchased a new rifle, first brand new firearm I have ever owned. I know it needs to be cleaned before it is shot. Anything special I should do other than some Hoppes #9 and patches?

I give them a complete wipe down to get all the cosmoline off of them. Clean out your bore like your said. I also blast the trigger with de-greaser then flush it with lighter fluid as it evaporates but leaves a tiny amount of non-gumming lubricant. Put a dab of grease on each locking lug and on the cocking cam. Stand the gun up with the action screws loose so as to seat the recoil lug in the abutment then tighten your action screws.

Excellent advice 7, I would add when tightening the screws tighten the front one (upper most when standing on butte plate) pretty tight then the rear screw snug and a bit more. If it's your first new rifle you may want to peruse some opinions on barrel break in---I subscribe to a shoot and clean every round for the first five then shoot 5 shot groups for the next 15-20 rounds. Some say it's unnecessary but if there are any burrs left behind after the chamber reamer this may smooth out.

I agree with you completely coy'master. I have had good luck with that torquing method in both bedded and unbedded guns. I used to subscribe to the shoot and clean for 20 and then every 5 for 100 but now I'm pretty much on your break-in process. After that I clean every fifteen rounds for non-coated bullets and about every 30-40 for coated bullets.

Thanks, I was wondering about barrel break-in. I have done some reading and it has been recommended to use lead bullets first to seal off the pores in the metal. Then switch to jacketed bullets however being that the gun is a 7mm Rem Mag I don't think there are too many lead bullets available for it. I'll follow your guy's suggestions and shoot and clean for the first five, then every 15-20 after that.

I wouldn't get to wrapped up with a special 'barrel break-in', steel is hard, bullets relatively soft. Nothing wrong with keeping the bore clean though.
Since I reload I normally use modest loads for initial setup.

I use Final Finish bullets on factory barrels if and when I shoot one. They will clean one up.
Custom barrels usually clean up really quickly during break in if chambered well.
I use the TMS bullets every 250 to 500 rounds depending on chambering.

I would also opt for UBC over lead

IMO I would not shoot lead bullets in the 7mm. I think they could get a bit "smeary" and lead fouling is not the easiest thing to try to remove. The barrel is meant to shoot copper jacketed bullets and that is what I would suggest.

Jims... Is correct,, no lead in a 7mm mag... The article you read must have been talking about big bore rifles and slow bullets or maybe a pistol caliber... But lead bullets in a hi-power rifle is a no no in my opinion...Jeff.

I clean to bare metal using jb, then hit it with Kroil, after that I lay down Moly. I don't touch the barrel after that until accuracy starts to drop off. I have over 1k rounds on my 223AI's and 25/284 without a cleaning rod down the tube.

If I am shooting bullets coated with hBN I have found cleaning can be less frequent. I also ran a test with a pair or match rifles in .223 Wylde and .308 Win and found you can shoot hundreds of rounds before accuracy falls off; both of those guns shoot 2550fps to 2650fps. I still clean my guns that top out over 3000fps (6mm and 7mm) every 30-40 rounds and clean the slower guns every 100-200 rounds. Luckily my barrels will patch clean with minimal fuss.
