kylethunder380 Posted July 15, 2011 Share Posted July 15, 2011 Hey guys, I know a lot of you have experienced slower jugs of Solo 1000 compared to 'older' lots. What I want to know: how much did you have to increase your powder charge to in order to reach the same velocity as your 'fast' jug(s)? I recently got a new jug and have already increased my 'old jug' powder charge by 0.3 grains and am still not there. I'm assuming it's not going to take much more, but I wasn't expecting having to increase my charge by 0.5 grains! Now I'm going to be worrying about pressure.. eh. Really sucks because I absolutely LOVED my old jug of Solo 1000. Has anyone else had to deal with this amount of variance? -Kyle Link to comment Share on other sites More sharing options...
Jay870 Posted July 15, 2011 Share Posted July 15, 2011 I had to go from ~3.4 to ~3.9. Somewhere on here I documented my "fast" & "slow" lot numbers too. Just got a new cannister and need to get that out the chrono soon, only have a few K worth of my "fast" batch and wondering how the new batch compares.

jar Posted July 15, 2011 Share Posted July 15, 2011 I found data here of 3.2 for a 133pf load with 147gr precision bullets. I had to go to 3.7 with the lot I have. Link to comment Share on other sites More sharing options...
DWFAN Posted July 15, 2011 Share Posted July 15, 2011 yep, .4-.5 gr difference for me. Link to comment Share on other sites More sharing options...
TAP Posted July 15, 2011 Share Posted July 15, 2011 (edited) My old lot was around 130 PF with 4.2g for a MG 124 CMJ. New lot using 4.6g is around 116 PF. I tried going up to 4.8g but the volume was too much IMO for a 9mm case. I still use the 4.6g load but I don't compete so it works for me as a training load. I'm not sure the slow jugs will make minor consistently unless you are using 135g or heavier bullet (due to case volume limitations).

slowhand23 Posted July 15, 2011 Share Posted July 15, 2011 (edited) Yea, I really liked my old lot #1877 so I bought a 4 lb but it was lot #1930. Big mistake, needed .5g more for MG 124 CMG and still barely made 125 PF. Edited July 16, 2011 by slowhand23 Link to comment Share on other sites More sharing options...
Torogi Posted July 15, 2011 Share Posted July 15, 2011 OP, what is your lot number on your jug? Link to comment Share on other sites More sharing options...
GSWEAR Posted July 16, 2011 Share Posted July 16, 2011 Also keep in mind that Solo is reverse temp sensitive, If your having high temps like we are here in the mid west and trying to match a load worked up in cooler weather could be affecting results quit a bit.

He said that if the FPS is the same the pressure is the same. Don't worry about it basically. This was their tech support guy. He seemed very knowledgeable. I talked to him several times about several different loads. Link to comment Share on other sites More sharing options...

ben b. Posted July 16, 2011 Share Posted July 16, 2011 The answer I got From Johann was that S1000 was intended for shotguns, and the performance between lots was acceptable for shotguns and within their parameters. Link to comment Share on other sites More sharing options...

That's some dumb marketing! They have lost a 'lot' of business because of the inconsistencies. Personally, I don't mind spending the time with a chrono every 8lbs. The results of using Solo 1000 is well worth it. Link to comment Share on other sites More sharing options...
ben b. Posted July 16, 2011 Share Posted July 16, 2011 I don't know. It's intended market is a shotgun powder, and Accurate thinks it is not a good choice for .40 powder, and markets their pistol powders for pistol reloaders. If some yahoos don't follow my recs for my products, I won't go out of my way to tell my tech people to convince the yahoos that acceptable variance in the intended use is not a problems in the yahoo use. I like S1000 for price, burn rate and relative clean/cool burn. 8 lbs loads a lot, and I don't mind testing either. Link to comment Share on other sites More sharing options...

Let's don't forget the soft felt recoil. And the lack of smoke with FMJ. Edited July 16, 2011 by atbarr Link to comment Share on other sites More sharing options...

Yes, at the time he said it was not really meant for pistol but for shotgun. Also, something about a new plant. Link to comment Share on other sites More sharing options...
kylethunder380 Posted July 16, 2011 Author Share Posted July 16, 2011 OP, what is your lot number on your jug? 1624 I can't seem to find a lot number on my old/fast/empty can? I called Accuratte about this a while back. He said that if the FPS is the same the pressure is the same. Don't worry about it basically. This was their tech support guy. He seemed very knowledgeable. I talked to him several times about several different loads. Well that makes me feel a bit better anyways. Thanks for the info. Also keep in mind that Solo is reverse temp sensitive, If your having high temps like we are here in the mid west and trying to match a load worked up in cooler weather could be affecting results quit a bit. No, this was in the evening so the temp was quite moderate. Link to comment Share on other sites More sharing options...
ben b. Posted July 16, 2011 Share Posted July 16, 2011 Capt Obvious sez: Remember kids, it's the temp of the powder inside the case that is important, not the ambient temp. If ammo sits inside a hot car at work until you get off to shoot in the cool evening that powder will be quite a bit warmer than the air. Link to comment Share on other sites More sharing options...

I have a friend that uses Solo 1000 for his AP loads and called them a couple years ago and got the same response. Greg Link to comment Share on other sites More sharing options...

I don't remember saying anything about leaving it in a hot car. The only thing 'obvious' from your reply is your patronizing tone.

I was pointing out that ambient temp may not be the same as the powder temp, and thinking of a case that I discussed with a guy that did that very thing. The Capt Obvious bit was in self-deprecating jest. Link to comment Share on other sites More sharing options...
cnote Posted July 19, 2011 Share Posted July 19, 2011 Has anyone noticed better accuracy with their loads closer to 135/140PF than 125/130 ish?? Link to comment Share on other sites More sharing options...
Tom E Posted July 20, 2011 Share Posted July 20, 2011 I have done "back to back" tests. Solo 1000: Lot 1930 was 4% slower than lot 1624, all things equal, shot back to back same day. Lot 1624 tested after being kept at room temp and transported to the range sitting on the dash in the sun was 1% slower than same ammo batch kept in my 0 F freezer overnite and transported to the range in a cooler and shot the same day.

I'm not sure the slow jugs will make minor consistently unless you are using 135g or heavier bullet (due to case volume limitations). Winding up near a compressed load at 4.6 ?? I thought it would have happened a lot sooner than 4.6. Edited July 22, 2011 by cnote Link to comment Share on other sites More sharing options...
