I took my ML to the range for the first time and the second shot was very hard to load,especiallythe last two inches. I'm using triple 7 powder with powerbelt bullets. I ended up cleaning the bore after every shot. Is there a way to reduce the crud ring so more than one shot can be fired without cleaning? I've heard of shooting with a wet bore, what does that include? Would the use of bore butter help?

After some searching I found out that 777can leave a heavy crud ring and my gun must not like the stuff. I think I will buy some American Pioneer Powder and see how that works. It sounds like a clean powder that doesn't leave much fowling. My only concern is that some sayit's less powerfull.

You could try using the loose 777 and/or a weaker primer. If you can find some 209-4 primers as used on 410 shotshells, some have had luck combating the crud ring that way. I have not had any problems with it myself and can load 8 to 10 powerbelts with out swabbing but accuracy is better if I swab. Using 250gr shockwaves I can shoot 6 or 7 without swabbing and still get good accuracy, after that I have to brush out the plastic fouling. Unlike some on this forum, I do notswab withalcohol or such before loading to shoot, just a few dry patches to get the majority of the lube out of the barrel, then pop a 209 or two and load as normal. Never had a problem with ignition and I have no crud ring. I also use automotive type antiseize on the breach plug and can shoot 777 all day and not have to loosen the breach plug till I'm ready to clean the gun at home, comes out with little more than finger pressure. If your gun is new, you will probably find that it gets better the more you shoot it, mine has 3 to 4 hundred rounds under its belt and I think it shoots better now than ever. Good luck and keep us posted.

What your experiencing is a hard crud build up caused by the Triple Se7en powder. Many shooters have to swab with a damp patch between each and every shot to remove that crud ring to make sure they are seating the bullet properly.

I swab with a patch that I dampen with 50/50 isopropyl alcohol and car windshield washer fluid (summer blend). I work that in short strokes from muzzle to breech, flip it and do it again. Then run two dry patches. This will normally remove even the hardest crud ring. If now wrap the damp patch around a bore brush and swab the bore with that.

Shooting from a damp or wet barrel is not a good idea. Moisture and gun powder do not get along. Even a little moisture can effect powder and there for give you inconsistent loads. It would be hard to judge the true potential of a load if every load was different. Shoot on a dry barrel.

Also the bore butter I personally avoid. It will also cause sabots to be inconsistent. Although some people do butter their sabots and claim it helps them load and they shoot fine. I have yet to see a manufacturer or bullet maker recommend such an idea of buttering a sabot.

As for changing powders, well that is an option. There are powders out on the market that make swabbing a thing of the past almost. American Pioneer, Pinnacle, Shocky Gold (American Pioneer filtered twice I was told), and Black Mag3. There is still some Clear Shot and Clean Shot floating around out there... I have been shooting some Pinnacle. It is a very clean burning powder, but does not like heavy projectiles.

One other powder is Pyrodex. I know a lot of people hate the mess of pyrodex and black powder for that matter, but hard crud rings do not form from the powders. They are also one of the most consistent powders for burning, still being produced. I've been told, a lot of the manufacturers test their rifles with Pyrodex which should tell you something. Yes the fowling is nasty, but you can load a second and even a third shot if you really had to, and with the 209 ignition get them to fire. I do it all the time with Goex. Goex is said to be even worse then Pyrodex. After all is done, you still have to clean the rifle at the end of the day.. no matter what kind of powder you use.

Good luck with your rifle.

Triple Se7en

Use weak primers like standard CCIs & the new Remington Kleanbores. Use loose FFF 777 & swab with a bore brush instead of a jag after every 2nd shot. That should alleviate most of that crud.

I had4 Remington ML primers fail to fire 2 pellets of 777. Since then, I switched to American Pioneer Powder FFG and Winchester primers. I use 348 Powerbelts (295's sometimes). No problems loading 7-8 Powerbelts without cleaning in between.I shoot an Omega Z5 and Encore 209X50.

Triple Se7en

What gun & was this after an all day hunt?

Hard to compare the two powders in the same pellet form since APP does not come in the Pyrodex/777 pellet shape or diameter. Had APP did come in the same pellet design, you would of encounterd the same circumstances.

In two separate tests I conducted using both powders in loose formula, I sat them side-by-sidein an open-door pickup seat for several hours in cold, damp conditions. Afterwards, 777 fired instantly & APP didn't due to it's sugary constitution.

I have 17 hours invested into shooting/testingtwo jugs of APP. I've conducted different types of weather/shooting tests with it. I like the APP powder when applied to inlines. My Omega absolutely loves it.

Just remember to keep the hottest Federal 209A primers nearby when hunting for long periods with any blackpowder or subsitute. Weaker primers like Remington Kleanbores cannot be trusted to fire your powder on foul, humid weather days.

It was a Pursuit LT, at the range, when sighting it in. In my opinion, the Remingtons are not hot enough................

I had a fascinating experience with primers recently. I was using Winchesters at the range with BM3.I bummed a few Kleanbores from a buddy to see what they would do. Lo-and-behold, the Shockwaves hit 6" low and sprayed over the paper.[:'(] Lesson learned: you can't just switch primers. Since T7 burns faster than BM3, the Kleanbores may be hot enough. CCIand regular Remington primers would be an in-between choice if the Kleanbores don't kick the T7 hard enough; I had good luck using regular Remingtons back when I was still using loose T7.

I tried using the Remington Kleenbore primers with the T7 pellets and it did not leave a hard crud ring! My point of impact also changed, which I will correct the next timeat the range. I shot 3 shots without cleaning at 50 yrds and the first two shots were touching and the third was an inch away. At 100yrds I put three shots within a three inch circle. They were just 4inches high and 4 inches to the right. I now have a combo that I'm comfortable to hunt with. Thanks for the input.
