I plan on getting a SP10 (in .308) soon and was wondering if there's anything I need to be careful of to preserve it's accuracy.
Also, when breaking a new barrel, is it necessary to use match ammo? Would, say, M80 Ball work?
I'm new to precision shooting (not shooting in general, I plan on treating this SP10 a lot nicer than any of my AR's) and would appreciate any info..

[@The4GunGuy]

Hi EpsilonNought! I would use a middle of the road ammo for break-in. During break-in, you're really looking for the barrel to "settle in" to a consistent velocity node, which will most likely climb to that node after x number of rounds (some of my rifles are broken in after 100 rounds, others it may take upwards of 200). Now, there is nothing that states that all you can do during that break-in is send rounds downrange, in fact, I've shot matches with a brand new barrel on the rifle and did just fine, as long as I understood when the barrel sped up...That's the key. But, back to your question, if you want to break in the barrel using ball ammo, I don't see and issue as long as you set accuracy expectations. Get to the range, practice your positions (see my videos on PRS stage practice) on some stages with the expectation that you're breaking in the barrel and accuracy may not be there using ball ammo. Once the barrel is broken in, I'd definitely move to a more accurate round. Hope this helps and thanks for watching my friend!

@@The4GunGuy Thanks!

Do you use any JB Bore Compound & Kroil on a new barrels and again after about 200 rds?

[@tonypipTexas]

Hi Philip! I don't use JB Bore Compound/Paste or Kroil, but I know some guys who do use them both religiously to take the barrel down to "bare metal". Some guys clean that way every cleaning, but I tend to agree with the "let it be a little fouled" camp so I don't have to waste rounds (and barrel life) getting it back to where it shoots the best. As I said in the video though, I don't think there is any real "right" way, just what works for you. In the end, we're replacing these barrels after ~3k - 4k rounds, so how bad can you really mess them up in that short period of time, unless you really tried of course! Thanks for watching my friend!

I watched your video on the SP10 first match with the good, the bad and your mistakes. I would like to see you give your SP10 another opportunity at matches.
I'm currently building a SP10 of my own for PRS matches, hope the results are great like my Seekins Precision DMR in 223Wylde that I also built.
What brass weight you are use in your SP10 handguard?

[@The4GunGuy]

Hi BimmerDude! I've shot the SP10 at a couple matches and really enjoy it, so it's all good. The brass bar from Amazon is: amzn.to/4bdFVOv and I drilled 3 holes in each bar and used these M-Loc screws/bolts to attach to the rail: amzn.to/3XyIJCE. Thanks for watching another one my friend and you'll have a blast with that SP10!
