BLC-2 and Reloader 10X , their burn rates are about the same, are they pretty much interchangeable? I'd like to work up some rounds with 110 TTSX and the only info that I've been able to find is based on 10x. I don't have any 10x but I have plenty of BLC. Thanks.

You'll see that this list has them right next to each other, just goes to show that you can't believe everything you read on the internet. Thanks.

Most sources will warn you that: Smokeless powder will vary in burn rate depending on volume, bore size, chamber pressures, etc.

The ranking of burn rates on a list will actually change according to these factors. That's why a chart or list doesn't have much value.

Burn rate chart aside I have used both and BLC2 is a slow ball powder suitable for very heavy .223 bullets or 308 loads and 10X is a fast 223 powder only suitable for the lighter bullet of 55gr and below, there really is a huge difference between the two.

On your chart RE10X should be above N133 and Benchmark so they have it misplaced.

+1 EWP. I've used BLC-2 and H380 for 223 loads and they are slow and similar. Nothing like a RE10X. Always a good idea to inquire on 68forums before doing something we are not familiar with because of all the big brains we are fortunate to have here.

Like I said I have the BLC2 and I also have H4198, will I have any luck with ether of those and the 110 TTSX?

The h4198 might work but it is a bit too fast with the 110 gr bullets. You need to stick with a proven powder in the 6.8 like aa2200, h322, 10x, ect.

BLC2 might do OK but it's going to take a FULL load of it, if you can find AA2460 it's a slower ball powder that does well also.

Bullet Weight: 110gr, Case Trim Length:1.676", Bullet Style:TSX, Primer:Fed 205, COAL:2.260", Barrel Length:16", Case:SAA, Twist Rate:1:10"

H322 26.0 2240, 29.0 2515 fps
RL-10X 25.0 2258, 28.0 2570 fps
AA 2460 29.0 2446, 32.0 2647 fps

I also have RE17 but there isn't much info on it , pretty new I guess. One other concern it that I'm loading TTSX not TSX due to the "tip" I think I'll need all the room that I can get. Thanks for the help I love this forum. :-)

The TTSX is long and will need to be loaded to 2.30" if at all possible, the charges will be a little lower than the TSX data due to the extra length but should be close enough for a giuide for starting loads.

Re17 is way to slow for the 6.8 so you'll never find any 6.8 data for it, it's better served in 308 and larger cartridges.

Tap I have seen that same burn rate chart and I don't believe that Benchmark is faster than H322 either. Reloader 17 is close to 4350 and like EWP states, it is way too slow.

It looks like the H4198 will work fine. I'll give try a try.

Tap, if you need to buy powders you will probably be happier with what EWP and Colt listed. Your H4198 is generally considered to work best in the 85-90 grain bullets. If you have the powder, give it a try and please post your results.

That's the best H4198 data I could find you, you may have problems with short stroking though since the powder is so fast but it will most likely be accurate.

I use both Benchmark and H322 in .223 with the lighter 52gr BTHP match bullets and I think BM is slower than H322 also, even in 6.8 you can load more BM than H322 and with a lower velocity so that's also proving BM to be slower.

I also shoot BM and H322 in both .223 and 6.8 and my 6.8 loads are much lower with more powder also.

I have loaded 32g of BLC2 into a case and it was a good compact charge (110g Prohunters). Others have used 36gr - I have no idea how they got that much in the case.

I pulled the data from this website after a search. Havent tried them yet. Have 4198 to try as well. Waiting on upper to arrive. Needed ammo to get it sighted in cheap.

What velocity did you get with 32 grains of BLC2 ?

Near 2500 even. It was way louder than the ssa loads. As others say its slow for the 68. I expect mos of the boom was unburned powder. Accuracy was spectacular. 3/4 by 1 inch group. Going for the 4198 tonight since I have empty cases to play with.
