45 Reduced Short Line Loads - Consolidation Thread

Post by SmokinNJokin on Wed Jul 27, 2016 11:32 am

I’m bringing a recurring topic back up because there are a few questions I still have unanswered after scouring a dozen or so threads. Jon and Jerry have provided a lot of great info in the past on the subject of reduced short line loads (VERY reduced, sub 4 grains).

A lot of this stuff has been talked about in other threads, instead of peppering questions all over the place I decided to just make a new thread to consolidate.

I currently shoot only iron sights on my .45, so results should be very similar to those running frame mounts. I run a reduced short line load, and have swapped recoil springs in the past when necessary. To help keep things simple, and less expensive, I run the Nosler 185 on the long line, and keep them in dark color ammo boxes. On the short line, I use lead or the cheaper 185 hornady (for CMP) and keep them in white ammo boxes. So it is impossible to accidentally mix long/short line ammo, even if they fall out of the box.

My questions are as follows:

[list="list-style-type: decimal; direction: ltr;"]
[*]Jerry has mentioned running loads as light as 3g bullseye, and also that he prefers Vectan to some of the other powders for reduced loads. I have been using N310 and WST, are these powders that reduce well? I have no problem using different powders for long and short, as the loading process is completely different for these ammos and I generally load large batches. What powders do you recommend for very light loads?
 

[*]I use a sprinco system and like it, it allows you to run a 2-4lb lighter recoil spring than you normally would and cushions the last bit of slide travel with an additional spring. With full-power loads, the system shines. However, I wonder if it is more of a hindrance to proper operation when using very light loads and a 7-8-9 lb recoil spring.
 


[*]I have used the exact same recipes for reduced loads on my jacketed ammo as with lead, but I have often heard you cannot reduce jacketed as much. What is the reasoning behind this besides the obvious greater friction and force required to deform a jacketed bullet to rifling? Are squibs more likely with jacketed, or is it an accuracy issue? I would not mind having groups open up by an inch or so at 25yds and lose X’s if it helped avoid random 8’s.
 


[*]My .45’s all have very well radiused firing pin stops. Should I fit square stops? Does it make enough difference in recoil and cycling with reduced loads that I should do this?
 


[/list]

I appreciate the input – I know a lot of this info is stuff I could eventually figure out on my own through testing, but why re-invent the wheel -  I would rather just spend that time practicing and not worrying about ammo and function, especially if some much-smarter-than me guys already have the answers.

I'm only going to hit this minorly right now. Squared firing pin stop for heavier charges. Squibs are from not enough powder.......normally a reloading error.

there are a couple of common paths for lighter(felt) short line loads..

one is to use the same bullets as your long line and simply reduce your powder charge and change your springs accordingly

another is to use much lighter bullets.. this typically means you have to use the same or a slightly increased powder charge and no change springs.

Right now I run 200gr HG 68s at both lines.. 4.0 of BE at the long line and 3.5 at the short.. this is for a slide mounted dot(sightron).. I do change my recoil spring to a 9 lb spring for the short line...

you can play with different powders for different feel on the short line.. I've found BE to what I like for the most part.. WST is very close.. N310 I find to be a bit snappy.. I do use it on my EIC loads as it works well with jacketed bullets.

as far as lighter loads with jacketed bullets I've never found them to be as accurate as the stronger loads...


I'm sure you'll get different opinions.. find what works for you

Forget squared firing pin stop it only helps when shooting full power 230 fmj loads, What cause's a squib is the reloader, its no powder in the case. be vigilant when reloading and if you can use a rcbs lockout die it will stop a progressive press if no powder or a over charge has occurred. It makes things simpler to shoot the same bullet at 25 and 50 with the same charge if its accurate and light enough. a 185 lswc with 3.9 of bullseye is a very accurate light shooting load.

I'm new to this forum, but have been doing "bullseye shooting" since the 1980's.  Setting up targets, and trying to get small groups.  I now do reloading.

You guys are already talking about things I never heard of before today (short line, long line), so I've got a lot to learn.


I think it fits in with this discussion, so I don't think I need to start a new thread. Last year I bought a Les Baer Premiere II.  I've been enjoying/struggling with it since then.  Either I have gotten stronger, or the gun has broken in, as I can now rack the slide - something that was durn near impossible a year ago.  Lovely gun, and my groups are between 2" and 3" at 15 yards.  Not very good.

Anyway, on to the question.  I started with Winchester White Box 230 grain bullets.  To reduce the power and the recoil, I started loading my own 230 grain bullets, with the lowest amount of Unique powder in the reloading book.  Thinking lighter would be better, I got some 185 grain Speer bullets, FMJ RN, and used Unique powder, and later Bullseye.  Again, the minimum amount noted in the Speer reloading manual.

People have suggested that I use 200 grain bullets, and what I've read so far on the Bullseyepistol.com website, that seems to be a reasonable thing to do.  So, two days ago, I ordered these:
   midwayusa.com/product/538777/speer-bullets-45-caliber-451-diameter-200-grain-total-metal-jacket-semi-wadcutter-match-box-of-100 

My current plan is/was to load them as before, with the minimum amount of (probably Bullseye) powder in the reloading manual.  Is there any information on this forum suggesting what loads are better for shooting paper targets?

Thanks in advance - now I'm off to find out what the difference is between long line and short line.........  I'm guessing it's the distance one will be shooting at.  (I almost always shoot at 15 yards, so I can compare targets equally.)

Welcome, Some like to shoot a lower recoiling round at 25 yards than they do at 50 yards and some shoot the same load at both, but which ever you choose....
First thing loose all the reloading manuals as per load info for bullseye, the lowest charges they list is most times well above what is needed and accurate for bullseye. The bullet you ordered should do well with 4.2-4.4 of bullseye and can easily be used for both short and long line use, but more costly to use, being most shoot the 45 for Center fire and 45 parts of a 2700 match. that's 180 shots and add in 10 alibi rounds for each so total of 200 rounds needed to compete. You would be just as accurate and save a lot with  a 200 lswc loaded with 3.9-4.2 of bullseye it will drill the X or 10 ring at 25 or 50yds out of your les baer all day long off a bench. A box of 200 lswc will run about 50.00 or less. 
A 2700 bullseye match consists of 3 parts, 9 targets shot with a 22, a centerfire gun 32 or larger and a 45 acp each of these  is capable of  a score of 900 and has 3 targets fired at 50 yards(long line) and 6 fired at 25 yards (short line) object of the game.... get as close to a perfect score of 900+900+900 or 2700 total as possible. Record holder for Highest official fired score to date 2680 fired by Herschel Anderson in 1974 in Nashville Tn.
For all the info on bullseye check out bullseye encyclopedia .com.

Thanks; I've got a lot to learn, but first things first.  Bullets arrive tomorrow, and I'll check out bullseye encyclopedia right now.  Again, thank you!

I like CJN Casting for 200gn H&G 68 SWC, http://www.cjncasting.com/45-caliber-Semi-Wad-Cutter-bullet-p/45swc200.htm

Like these too http://www.rozedist.com/mm5/merchant.mvc?Screen=PROD&Store_Code=RZD&Product_Code=R186-A&Category_Code=ZSB-45ACP

Terry at Magnus is great 802 or 801  but i would  try the 802 first

http://saas.shopsite.com/magnusbullets/store/page8.html

I have been shooting 3.9 BE, 4.1 WST, 4.6 W231 for every thing,

I usually look at the factory load data and then extrapolate down generally bullseye loads are 7% lower than the minimum  

Common powders used are vvn 310, bullseye, tite group, clays, 700x, w231, wst; A mid range powder like universal is really for steel 

I am current experimenting with VV320 and I am loading 4.2 which is bew the advetised min

Does anyone have experience that they could share with 3.0 gr of bullseye with a 200 gr LSWC?

I doubt it will function in a 1911, why are you looking to load so light?

Just curious as to how light I could actually go and still have good results.

I've used 3.0 gr BE with 200 lswc for 25 yds but think 3.3 gr should probably be minimum. I think there isn't enough benefit from the lighter charge to go that low without a reduced/lightened slide. Mainly for reliability; cycling (temperature/cleanliness). I've used 3.3 gr regularly in 5" & 6" slide mounted scopes for several years. Not sure how much difference it makes but I hold really hard. Stuff works for me that won't function for others. So good luck Smile

Tim, no need to reinvent the wheel, just go here, its at top of the ammo page its loads from guys who have all made master or above, any of these loads will yield great accuracy from any accurate gun.

So we drifted off topic a bit, I originally was only discussing jacketed short line data. There didn't seem to be much info out there so I went ahead and made up some lots of ammo with N310 and WST and Hornady 185 xtp ammo.

Bottom line up front: accuracy completely degraded with anything lighter than around 3.8 grains. Massive SD and spread. YRMV depending on the barrel, but mine certainly did not like very light jacketed loads. 3.8 WST is my new short line load.

A slight mis print...
2.9 to be exact..
This target was shot yesterday..12 strings of rapid fire with 2.9 gr. and 185 gr. lead.. on a turning system.. The shooter must be able to "shoot the turn.." and why I am so adamantly against stationary electronic targets..
2gr. for the 52/38 at short line...

52 / 38 long line...not yesterday..just sayin..

Jerry- do you have any thoughts about using Titegroup either at the long line or short? I've settled on 4.6 for 185 Noslers, but am certainly open to changing my mind if you've heard/had experience with Titegroup at eithe SL or LL

Mighty fine shooting, btw. Is this from the lady shooter you sponsor?

Thanks,
Chase

Sorry Chase, I tested Titegroup briefly, but the snap it produced wasn't what we were looking for.. So we didn't test any further.. Plus, everything we shoot is lead..softer recoil... When I started into bullseye in the mid sixties, jacketed bullets were very rarely seen on the line..Not as many 2600 shooters in those days, but some very nice groups where put up..Optics had not hit the scene yet.. I wouldn't even consider jacketed now..
Yes, that's her practice day..

Thanks for the feedback, Jerry! I have a lot of it around, and would like to use it. Of course, I have a jug of Bullseye and BE-86; the 86 is supposed to be used in the Federal GM 45- but I've only read that on the intertubes, so take it for what it is worth.

Mind sharing what 45 lead bullets you happen to favor?

Best,
Chase
