With magnums I scrub the bore to bare steel every 150-200 rounds. The carbon ring forms fast when you're sending that much copper and powder down your bore every time you pull the trigger. The only thing that will get hard carbon out is abrasives. JB bore paste is what I use. It will really bring a barrel back to life.

You alright? You sound tired or possibly sick. I wish you the best. Get well soon. A Merry Happy Healthy Christmas to you and your family.

Very well could be a scope issue. Watch Quarter Minute Magnums video on a Khales scope that went south. Just a possibility

[@Mikepavel1]

Great Content. Love the real world results and not just showing the best groups you end up with.

[@guardianminifarm8005]

Thank you. Appreciate the demonstration and discussion with perspective. I have shot 7mm Rem Mag a good bit for many years(30+) without any recoil reduction. I have also shot 308 a decent amount for a while off and on the past 20 years. I enjoy both but I would agree that I can get fatigued with my magnum rifles in load development and multiple groups testing much quicker than the lesser powered cartridges. I hadn't really given much consideration to it but now that you mention it I agree. For those out there thinking about a big rifle or a smaller chambering this is a factor you may want to consider. The amount of powder being burnt per shot is another factor. Thank you.

Keeping the crown clean makes a big difference. If the barrel is button rifled that's way to small of diameter for muzzle threads, even if it's cut rifling I wouldn't go that small. I really don't care for a threaded muzzle on button rifled barrels.

[@Bojangles6]

Why is that? Because the threading makes a non concentric radius?

[@javiersp01]

​@@Bojangles6it stresses the material

[@disfordiesel8219]

I have 5/8-24 threads on a button rifled 338, its fine. I get your point though, a bigger thread would be better.

[@rustynut1967]

@@Bojangles6 Generally removing material from the outside diameter will distort the inside diameter. It usually causes the inside diameter to constrict on a button rifled barrel, like a choke. It can effect accuracy but not always.

[@Bojangles6]

@@rustynut1967 interesting. I wonder if they were die cut instead of single pointed if it would still distort.

You need to get off the bipods and shoot off bags for that distance. If you want to stay with the bipod, use a foam mat under the feet. Your getting bipod bounce on a hard surface that isn't quite as apparent at 100yds.

[@RobsReloading]

@@jeromyknepp6643 I think you may be correct

Keep it up!

[@rockylongbrake1703]

I’m with you. Recoil sucks!

[@jamespollard1670]

Something is amiss ?

[@jbpmidas]

Really looking forward to more x47 content!! Possibility: on your 100 range do you preload into the block on your bench? Theres no block at 300 so the shooting style may have changed.

[@RobsReloading]

I’m actually going to test this

[@bigracer3867]

What ya hunting with those 🎉

[@chrisfisher3900]

Well that has to be disheartening. Went from 7 saum to 00 buck

[@jtstovall4]

I know you are human now 😂

[@DanielReyes-hz1qk]

Very strange. Maybe they don't like that seating depth? I've never had Berger's not group at least decently

[@RobsReloading]

@@DanielReyes-hz1qk I’ve got some ideas that I plan to test…

[@DanielReyes-hz1qk]

@RobsReloading Look forward to seeing what you find out down the road.

[@ThinkSoberly]

Can’t wait to you iron out the wrinkles. Then it would be cool to see you stretch the 7 SAUM out to 1 Mile!

[@brianmazgay9728]

Get a 7PRCW and use triple nickel with 180 berger hybrids
