ArrDave Posted August 21, 2015 Share Posted August 21, 2015 So I loaded up some LSWC to see how I liked them. Seem pretty accurate, I really like the recoil impulse. I shot 4 stages last night and had at least 1 round on each stage skip under the extractor then get jammed on the feed ramp as the extractor hit it. It took precious time obviously to clear that so that was no fun. So my question is primarily, is that due to the round being too short where it's coming up at too steep an angle and missing the extractor? Obviously mags play a factor (Checkmate Hybrids) and the gun does as well (Dan Wesson Valor), but my initial question, just thinking it through it seems logical that the ammo is too short. what OAL do you load your LSWC to get them to feed? These are set to 1.225, but due to mixed brass, some wind up a little shorter/a little longer. Link to comment Share on other sites More sharing options...
Steve RA Posted August 21, 2015 Share Posted August 21, 2015 I load mine to 1.250" with out problems. Try that and do a "Plunk" test after loading, you could have a short chamber. Link to comment Share on other sites More sharing options...
TDA Posted August 21, 2015 Share Posted August 21, 2015 1.250" here as well, which is .010" short of the rifling on my 1911. Link to comment Share on other sites More sharing options...
zzt Posted August 21, 2015 Share Posted August 21, 2015 Although mine will pass the plunk test at 1.250", most will not feed reliably. When I load to 1.240" the problem disappears. Link to comment Share on other sites More sharing options...
greg2648 Posted August 21, 2015 Share Posted August 21, 2015 1.250 in my Les Baer. Feeds perfect with no issues. My Springfield XD45 won't feed them at any length. Link to comment Share on other sites More sharing options...
Postal Bob Posted August 21, 2015 Share Posted August 21, 2015 Load mine to 1.25 also without any problems. There needs to be some lead from the bullets shoulder above case mouth, otherwise the case mouth hits the feed ramp causing problems. You also said the case rim "skip under the extractor". Do you mean it didn't slide under it? If so, you also should check the extractor's tension and clearance. It may be too tight, not allowing the cartridge to slide under it with the greater angle of using lswc. I have mine with a lot of clearance, and never have a problem.

TDA Posted August 21, 2015 Share Posted August 21, 2015 These are set to 1.225, but due to mixed brass, some wind up a little shorter/a little longer. I'm not sure I follow how mixed brass would affect seating depth of the bullet. The back of the case is against the shell plate and the seating die is against the bullet, so case length should have no relevance. So how does mixed brass make a difference?

There is a variance of +/- .005 with most probably falling between +/- .003 on all of my ammo. I'm very consistent with my stroke, I really can't explain why.

There's flex in the shell plate on a progressive. Brass which is harder to resize flexes the sizing station side of the plate down more and results in a longer OAL. Vice versa with brass that's easier to size. OP - post a pic of a loaded round. Generally loading SWCs you should not be loading to a book length unless the book data is based on the exact mold of the SWC you're using. You should set OAL based on exposed bullet shoulder above the case mouth. You want 1-3 business cards worth of bullet shoulder exposed. There are many different SWC profiles - even for 200 GR .45 SWCs. One size does not fit all. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
TDA Posted August 21, 2015 Share Posted August 21, 2015 I'm not seeing it with my XL650, which is why I asked. Mine may vary a couple of thousandths at the most. Link to comment Share on other sites More sharing options...

Sent from my iPhone using Tapatalk I don't have some rounds handy, but I'm not at 1-3 business card lengths of shoulder... At 1.225 it just barely clears, it's visible, but not by alot. I suspect at 1.24 it would get me there comfortably. I don't have much experience loading SWC, but I do very much like the accuracy, beautiful big hole, and recoil impulse of the 200 grain projectile.

Yeti Posted August 21, 2015 Share Posted August 21, 2015 Just as Peter mentions.... For SWC style bullets, let the OAL be set by the individual bullet design. Focus on setting the seater die to leave a 'thumbnail' thickness ( 3 business cards, aka 0.5mm-1.5mm) of bullet shoulder above the case. Don't cut it too close because stacking tolerences can leave you with bullet shoulders inside or even with the case. Link to comment Share on other sites More sharing options...
warpspeed Posted August 21, 2015 Share Posted August 21, 2015 (edited) Which bullet are you loading ? Blue Bullets 200 gr LSWC. I would ask them what they recommend for an OAL. In looking at the profile from the picture they have online, they look different than the traditional H&G68.

techj Posted August 21, 2015 Share Posted August 21, 2015 (edited) When I was loading Blue Bullets 200gr SWC, I ended up at 1.224 for reliable feeding. Even then I would have the occasional hiccup (about once per 200 rounds) and just went back to the Blue Bullets 230gr RNFP which run 100% for me.

copecowboy22 Posted August 21, 2015 Share Posted August 21, 2015 When I used SWC in in my SS gun I loaded out to 1.260. I was having 3 point jams. I got my barrel throated and started loading to there and the problem went away. Link to comment Share on other sites More sharing options...
ArrDave Posted August 21, 2015 Author Share Posted August 21, 2015 When I used SWC in in my SS gun I loaded out to 1.260. I was having 3 point jams. I got my barrel throated and started loading to there and the problem went away. I had a new shiny barrel in my gun, I just had it throated and test fired 120 rounds, no issues. Also unearthed that I'm not using enough crimp and that was exacerbating the problem. Link to comment Share on other sites More sharing options...
HotRod61 Posted August 23, 2015 Share Posted August 23, 2015 Sorry for the ignorance. What is a "Plunk" test? HotRod Link to comment Share on other sites More sharing options...
biglou13 Posted August 23, 2015 Share Posted August 23, 2015 (edited) Plunk test is dropping loaded round into barrel. Some include drop in and spin, drop spin and bullet drops out.... +1 on plunk +1 on 1.25. I load blue bullets. The 200 gr swc is most reliable I've found so far. +1 on crimp ... Without further info I'm betting your issue is here..... Don't ask me why...... Sharpie test failed bullets. And sharpie test random to see if you can find fault Clean and lube gun well, how dirty is gun since jamming Pics of jam How old and what weight recoil spring Have you measured cases after sizing. ... Case length Do your loaded cartridge pass roll test , cocentric How many times have cases been fired Are certain head stamps causing issue Edited August 23, 2015 by biglou13 Link to comment Share on other sites More sharing options...

noylj Posted August 26, 2015 Share Posted August 26, 2015 Many times, this is a magazine issue (when the magazine lips release the round for feeding). I prefer my .45 L-SWCs to just barely touch the lede/rifling. Never had any feeding issues in almost 35 years (after I junked the cheap GI magazines that were around then). Try some other magazine. The lips should release the round at about the halfway point along the lip. In terms of COL, in general, if the round jams in the feed ramp, the COL is too long and if the round jams in the barrel/barrel hood, the COL is too short.
