    j1480, you misinterpreted my post. I prefaced by writing "may be at work", not were at work. I was not criticizing your chrono technique, just passing along some info I learned the hard way. I always wondered why I got so much less velocity than the VV loading manual stated. After doing some quick calculations I discovered my chrono technique was a part of it. Any bullet path not directly down the long axis and parallel to the plane of the sensors is longer. So the time of flight is longer, and the chrono reports a slower velocity. If your off axis POA is consistent shot-to-shot, the reported velocities will be lower, but the SD will be accurate. If the paths are not consistent, both velocity and SD will be incorrect.

    As far as powder drops are concerned, the only way to know what you are actually dropping is to operate the press until loaded rounds are dropping out, pulling the bullet out of the round under the seating die and weighing the powder. I do this several times. I have found that when I initially set up the charge before loading starts, I get consistent results. However, they are always heavier than what is thrown when actually loading. The vibrations of the machine and the way you operate it affect the way powder settles in the measuring chamber. The same thing happens if you have a jam up. The next drop is going to be off, so you better measure and correct it.

    Fair enough. I was about 3" to the left at 18 yards. I didn't correct this until after the chrono sessions, and now my windage is dead on at 25 yds. I've got a new front sight coming in to correct my elevation, should be here in a day or two. I may very well repeat the whole ladder once I've got my sights dialed in. I have about 1,600 more Freedom Munition rounds to practice with before I have an actual need to start reloading.

    Hmmm, that is a fair amount slower than what I am getting. My guess would be either you simply have a slow barrel or you have a slow lot of powder. Have not heard of this with E3. I used to see large swings in loading needs between lots with the IMR powders when I used them.

    It seems like it would be one of those two. I was hoping someone would come along with chrono data for the Freedom Munitions ammo so I could narrow it down.

    By inconsistant with what other report, do you mean velocity? Yours seems to be low.

    Yes, velocity. Mainly based on your posts where you achieve major at 3.6-3.7 gr.

    There may be several factors at work here. First, you say that you weight ten drops and then start loading. Well the powder drop for the first loaded shell will differ from the second, and that will differ from the third and fourth. For the most accurate results, you should run at least 6 or 7 rounds before you start to collect the ones you will shoot in competition or chrono.

    I adjusted my powder measure, then dropped ten charges, then threw that back in the measure. Then I measured 10 charges to establish where my measure was at. Then I started loading. Isn't that the normal method?

    Second, your barrel might just be incredibly slow.

    That's what I'm starting to think.

    Third, your chronograph technique needs work. Unless you are firing all the rounds exactly down the axis of the chrono and dead parallel to the plane of the sensors, your reading will be slower than the actual velocity. Small variations can make astonishing differences.

    I haven't had a problem with the thousands of other rounds I've fired over my chrono. Seems a little harsh, but ok.

    I to load 180gr LTC and polycoated TC for my TS at 1.126" OAL. My Major load is 3.6gr e3 under a Falcoated 180gr for 172PF (950fps). 3.7 does it using leadTC bullets. SDs are always in the single digits. BTW, I don't get the velocity variation you report for the 4gr load at 72 and 58 deg. I get zilch.

    I don't get it either. That's the point of this post. I'm seeing what I believe to be temperature based velocity swings (which others have reported not to exist), and far higher charges than others have reported to reach the same PF. I loaded up about 200 4.2 gr bullets so I could dial in my sights better after doing the chrono session. I went ahead and fired most of them over the chrono because it was still set up, and I saw velocities that were consistent with my 10 round test group of 4.2 gr.

    3.6gr e3, 180gr Falcoated, 170pf, 1.126 oal in my TS.

    I used your load as a starting point with Bayou 180 gr TCG bullets loaded to 1.126. I bracketed it and ended up with charges of 3.2-4.0 in 0.2 grain increments. I figured that would get me where I wanted to be in my CZ TS. 4.0 was almost there, but I had 2 shots that were sub major. I'll have to try 4.2-4.6 and see where I end up. Here's my data. My chrono didn't pick up all of my shots for 3.8; that's why the data is missing.

    I've read bad things about the Blade-Tech race holster. I got the regular ol' Blade-Tech OWB on the BOSS hanger. I have been thinking about getting and modifying a DAA Racemaster, but the Blade-Tech is working great and I don't really feel like spending another $200

    I've used a stock .40 TS for the past year and have used Winchester SP primers without any issue the entire time. Now holsters...... that's another story. But the Winchester primers are a Non-issue.

    Good deal, I ordered 30k of them. I'm using a Blade-Tech holster on a BOSS hanger for mine and have been really happy with it.

    Ideal bench height, what am I missing

    in Dillon Precision Reloading Equipment

    I reload while standing; never felt I could get the needed leverage while sitting. From what I'm gathering, the shoulder measurement idea is no good. It would appear that everyone likes something different, and there is no way to measure this out, so here's what I think I'm going to do. I'm going to mount the new press on my existing bench. I'm going to make a platform that I can keep adding height to. I'll keep making it taller until I feel like I've found my ideal height, and then take measurements to make the new bench.

    my bench is 44' tall and my handle with the same set up as you describe sits at just below 59". I wish it was a little bit lower. I'm 6'3" so depending on your height you may want to lower it a bit more. I do like having the taller work bench but it did make my press just a tad taller than I needed it.

    The other thing is it makes my case feeder/ bullet feeder tall enough that I need a small step ladder to load brass and bullets

    I'm 6'1, so I'm guessing I would want it 2" shorter than what you would want. If you could rebuild your bench right now, how tall would you make it?

    I ordered a 650 with a 650-only strong mount, and I'm trying to draw up some bench plans. I'm running across a lot of conflicting information, and I'm wondering what I'm missing. I read that ideally, I want the handle at rest to be even with my shoulder. I'm also reading recommendations from quite a few places that say the bench should be 36", 42.5", etc. If my shoulder is 60", then I'm coming up with a bench top height of 45.5". What am I missing here?

    Springfield EMP 10 Round mags

    I called Springfield twice yesterday and spoke to two different people who denied the existence of a 10 round, 9mm EMP magazine. I called MecGar and left a message, but didn't receive a call back. If anyone knows about these things, they're certainly holding it close to their chest. I did sign up for the Gear Up and Go promotion, so maybe I'll end up with a couple of 10 rounders through that program.

    My belt has worked great except for the Velcro belt keeper. The stitching has pulled out. I've been using a DA keeper till I have something else to order from them and can buy a replacement.

    I've been having mine for about a month now, and I've experienced the same thing. The belt itself is great, the keeper wasn't very good. Recently replaced it with an Arredondo belt keeper, and I'm very happy with this setup now.

    You can ask "logman" on the 1911 forum. He's been making them flush, which requires welding, but is the added cost (2 mags + labor) really worth it to get 1 extra round in the mag?

    I guess that would depend on how many 10-round mags the extra mag could make. If it would require two 9-round mags for every one 10-round mag, then no. But if I can get six 10-round mags out of eight 9-round mags, then maybe. I guess I would have to talk to him. Do you have an email address? You can PM it to me if you do. I'm not a member at the 1911 forum, but I suppose I can sign up if you don't have any contact info.
