LtDan, what range were you at, 100m or so?
I use a nylon brush but it is a little tight. Using Montana Copper Creme to deal with the copper fouling. I had started to the testing with CFE (Copper Fouling Eliminator) but after that I used a lot of other powder bullet combinations that dirtied up the barrel. I need to get a bottle of Montana Copper Killer to follow the creme. THe reason I knoe this stuff works well is I cleaned the rifle after shooting it with the normal stuff I usually use Hoppes 9, Bore scrubber. THen I came home with this Montana stuff and I run a patch through and dang a lot more gunk came out of the barrel.
I'm really really cautious on anything that will eat copper these days. From Krieger, Compass Lake Engineering, and other higher end barrel manufacturers, I am seeing more and more articles of people doing more damage to their rifles due to harsh solvents and things like Sweet's 7.62 and other copper/lead removers. Do a bit of research and look for them but it seems as though the guys winning places like Camp Perry and other national matches are saying more and more to just flat out not clean your barrels because you will do more harm than good. Lots of crown damage, and lots of pitting and bore problems due to harsh chemicals, and steel brushes or even misused bronze brushes.
Yesterday I decided to try a different approach to finding an accurate load. I have found that me rifle seems to like the 60 grain Sierra HP bullets. So I loaded 5 shells each of the following powders to about 2900-3100 fps. They are XBR8208, Varget, TAC, BLC-2, H335, AR-Comp, CFE 223, RL15, and 4198. I just wanted to see what powder/bullet combination works best. I hope I can go out to the range friday to run this test. You can literally drive yourself crazy with all the combinations available but what the heck what's retirement for.
I usea nylon brush, and a plastic jag on a stainless steel cleaning rod, I also use the Otis cable to do cleaning. Yes the barrel is somewhat tight.
OK went to the range today with 5 rounds of 6 different powders and the same bullet the 60 gr Sierra hp which has been very accurate with my MVP. I also did the same powder load for 3 60 gr bullets of different manufacturers. I thought the groups would be better CFE and Varget showed the most promise. To make sure I wasn't just hope and spraying the last target is my AR 15 24" Bull Barrel, timney triggered with a Vortex scope. When I got home from the range today my Nikon Mildot was waiting at my front door so may be I can improve on some of those groups. It's really not fair to all the powders tested as each powder has a load characteristic that needs to be developed for the barrel. I tried to get the velocities around 2900/3000 fps. Then I went with the same powder load for all the 60 grainers I had which was Nosler,Sierra,and Hornady. The wind today was coming at me at about a 20 degree anglefrom left to right and gusting from 3 to 7.5 mph. The CFE was the first target after 3 fouling shots also the best group. All targets today were 100 yards.
Went out today to try some loads and came up with the best group I've shot so far. I'm using CFE223 25.5 grains with a Sierra 60 gr hp, Rem BR primers and OAL of 2.250. I'm using a Jard 19oz trigger and a Nikon 6-18 scope. Measures .640 ctr to ctr at 100 yards
Looks like you found the right combination! I am planning on experimenting with Corbon loaded Barnes 62 gr DXP soon.
I just spent last Friday out shooting dogs. I was using some cheap PMC 55gr FMJ. Not exactly the best load for dog shooting. I went through 200+ rounds with no ftf or problems. I took over 100 dogs from 75 to 300 yds out. I also used some Russian Brown Bear in 62gr soft point. I did not notice any difference in accuracy. At the range I get 1" groups all time at 100yds no matter what ammo used. I am not the greatest shot but this gun makes it look like I am. Going out dog hunting again this weekend and will be using 55gr HP Herters from Cabellas. Should make those dogs explode.
I shot a group of 5 at 100 yrds and got a group the size of a quarter with hpr 60 gr bullets. the remington 55 grain umc ammo is scattered 2" moa maybe but i am still in the testing faze myself. i did go goffer hunting and was picking goffers off at 200 to 250 yrds with the hpr 60 grain bullets.

Have been shooting Privi Partizian 55gr FMJBT with great accuracy. I am at one inch at a 100yds (they are also running through the crony at 3400fps +/- 30 fps). The Privi 69gr match HPBT are .75 or better. I am going to try the 75 grain Hornady Match chambered in 5.56 soon. Bottom line, this thing can out shoot 99% of the people using it in any hunting situation unless you are using a lead sled and a bench for dogs or something. This has got to be the best $509.00 I have spent on a weapon. I am using a Nikon prostaff 4x12x40 for a scope and am very pleased.
Wow! Pics are on my phone to post when I get home. First go at 200 yards today with the new gun was amazing. First shot was off as the rest was not right and I rushed it so I changed to the bipod and a sandbag. I then shot a 1/2" group of 4 shots, AT 200YARDS! Hornady v-max 55gr. It shot everything great. My friend shot a 5 shot ragged hole at 100 yards with monarch 55gr $5.99 ammo.
Well here it is. You will see my first shot up and left on the bad bench rest. You will also see the .300WSM rounds a buddy was shooting with his $4,000 rifle and Swarovski Scope.
Nice shootin Trey! 200 yards is a nice little poke! Makes it difficult to wipe the perma-grin off your face when your shooting groups like that! I have come to the conclusion that the MVP is one hell of a rifle for the money and it loves the Hornady V-max bullets. If it makes your buddy feel any better, I have some 300 WSM for cheap in the Classifieds section. It won't help him shoot tight groups like you with your MVP, but it might ease up on his wallet! Do you plan on doing any hunting with your MVP or just punchin paper?
I'll do some hunting with it but mostly paper punching.
I've got some more shooting to do but ran out of time to be organized on Tuesday.
Hey all, new to the forum here and loving the MVP. I threw a Vortex Viper HS 4-16x44 on it and my god does it shoot. As far as loads go, you gotta stay light with this firearm. The best thing I've found after messing around with a few different combos is 26 grains on varget behind a 50 grain nosler ballistic tip varmint. Another sweet load for coyotes is the same powder behind a 36 grain Barnes varmint grenade. Both loads are quarter inchers at a hundo, with the Barnes chronoed right at 3340 and the best velocity for shooting paper with the 50's is to keep it right below 3200 fps.
Gotta stay light. 40 to 50 grains at 3200 or less. Perfect.
