What has been your experience using the BlackMag3? I presently use Triple 7 and am thinking about changing to BlackMag3. Any input will be appreciated...

There has been a lot of discussion on several sites relative to Black Mag'3. Personally I love the stuff in my stainless Omega. Many other Omega owners have the same results. Personally I hate 777 in my Omega as the crud ring I get is way too much trouble to deal with (severe crud ring requiring brass brush as well as multiple patches wet and dry to clean it out after one shot. Black Mag'3 seems to work the best in longer barrel rifles (longer than 22inches). The burn rate is significantly different from 777. 777 has a sharp pressure rise right from the start which results in a sharp slap like a magnum rifle. Black Mag'3 tends to have a slower pressure rise rate but sustains the pressure longer resulting in the same or higher velocity than 777 if the barrel is long enough, and the big plus is that the felt recoil is much better with Black Mag'3. I am just starting to evaluate the Goex Pinnacle which is a powder with similar formulation to the Black Mag'3. The Pinnacle should be purchased as fffg however as the ffg is very coarse. Black Mag'3 only comes one granulation which is fffg in appearance.

It doesn't leave much fouling and cleans up easy. The main drawback is price, it's about $30 lb around here. :shock:

I have shot both BM3 and 777 both, and have to admit BM3 is definately cleaner (also more expensive and harder to get). They both shoot great in my Stainless Omega since I started using the 25 acp conversion. For some reason, just luck I guess-I have never been cursed with the infamous crud ring that many 777 users complain about. Its a toss up for me, I use them both and like both of them.

Hiker270: What loads do you shoot in your Omega? I have a devil of a time with the crud ring in my .50 Stainless Omega either with or without the .25ACP conversion (worse without the conversion). What 777 powder ffg or fffg? What primer? How much powder? What bullet or bullets? How do you compress the load; heavy compression or just light packing? I would sure like to understand what makes 777 so big a problem in some rifles and some "identical" rifles have no problem at all.

Keith: I am also amazed at the different results forum members have with identical inlines, powder and primers. My inline is a stainless-synthetic .50 cal. Omega. I have shot nearly 2 lbs of 777 2F out of it in the last 2 years and it loves 105 grs. with nearly any bullet I put down the barrel. I have shot 195,220,240 Dead Centers with good results. 245 Gr. Powerbelts shoot excellent also. My load of choice over the past month has been 105 Grs. BM3, 250 Gr. T/C Shockwave. I now have converted to the 25 acp. instead of 209 primers. Although I had about the same results with Rem 209-4 primers. I had no luck with BM3 until I went to the 25 acp conversion. Now both 777 and BM3 shoot nearly identical in my Omega with the nod going to BM3 for being cleaner. I have never had any real issues with a crud ring using 777, although when I shoot groups I spitpatch-drypatch between shots for consistency. I have no problem shooting 4-5 shots using the 250 T/C shockwave and not cleaning between shots with 777 or BM3. As far as compressing the load I would say mine are on the light side, I have observed if I compress too heavy it will shoot a bit high, not sure why but it will do it every time. I have to say I am very pleased with my Omega, I have and Encore also and the Omega outshoots it all the time.

Good information but would still like to know brand of standard 209 primers that you use with good results and also brand of small rifle primers with the .25ACP conversion. I have used mostly Winchester 209 and Winchester small rifle primers. Maybe there is a problem with Winchester. My Omega is stainless synthetic real tree camo. I have all three styles of breechplug plus the .25ACP one.

The standard primers were Winchester and the Small Rifle are CCI. I started using Rem 209-4 after reading about them in this forum. In my Omega it really never seemed to matter what primer I used. I have 2 -209 breechplugs, they are both deeply concave faces. I could only shoot 777 before I got the 25 acp conv. because if I used BM3 it would clog up the hole in my breechplugs. I like most users prefer the 25acp conv. because its cleaner and the cases are much easier to put in or extract. After spending last weekend at the range I am confident my Omega will shoot either BM3 or 777 using the 25acp conv. with equal results out to 100 yds. This afternoon it gets tested at 150-200. I am heading to North Carolina next weekend for their early muzzleloader season and we'll be hunting whitetails over soybean fields where some shot opportunities may be long. Like I stated before it amazes me how different these inlines act, even the same make and model. With my 209x50 Encore I have not been able to duplicate the results I get with my Omega. The Encore is strictly a backup.
