Getting ready to make my first loads

Well finally got back in town for a week and was wanting to make my first loads. I wanted to run by everyone to make sure that I got this right or I am going in the right direction.

Berry's RN 115 gr--use low mid to low charges for plated
Hp38--Hogdon's sais to start at 4.7 for SPR GDHP and Lyman sais to start at 3.5 for JHP
OAL set at 1.103--close enough to 1.100
Crimp is at .378, goes in correct in the case gage and barrell

So I guess make 10 at 4.7 and then 10 more at 4.9 or should I start at around 4 gr and work up? What am I not seeing or thinking of correctly when looking at both Lyman's and Hogdon's information? I used Lyman's 49th page 341 and Hogdon's online data. Also when I measured some blazer and winchester 115's they were coming in around 1.153 to 1.155, is 1.100 too short and also how close do I need to stay to the OAL as in 1.100?

i think you are on the right track, but i would just load up about 50 or so @ around 4.5grns and see how they do, and go from there.

If it helps any at all,

I reloaded for my fathers Glock 22 .40 Cal. I just stuck to the manual. Loaded up 15 rounds for him.

They were Remington 155 GR JHP
The COAL was 1.125. I try to get them there as best as possible but some come in at 1.124 or 1.122 ETC. No big deal with in a -/+ 0.005 to what the members here at THR have said.

I also used the low end data just to start of with. Personally, I would stick with the data of the manual but that is why we have more than one, To cross reference the data.

Other than that, I would have to agree with FlyinBryan. Be safe.

I have found that 4.5 gr 231 (HP38) with 115 gr bullet works fine for my 1911, don't know about Glocks.

What's the purpose for the ammo? Plinking? Competition?

If these are you first reloads, I recommend ONLY loading "ONE TYPE" of bullet.
The Berry's 115gr rn bullets would be a good place to start with HP-38.

Start light. Load 10 at the low end, and 10 more .2grs higher, and 10 more .2 grs higher..

Shoot these on three targets, lightest ones first. Check each for function, group size and 'feel'.

The 115gr rn Berry's bullet OAL can be loaded to near SAAMI max with no feeding problems You can use the low to mid-range published data for a 115gr FMJ and HP-38.

Let us know how they run.

You are definatly on the right track. I have the Lyman Pistol book and not a big fan of it however. Not trying to slam it, I started with it a few years ago as well. I cross reference it as you are doing if I use the data and find it to start very low. I have moved to Hornady and Sierra books, and like both of them and had no issue at all. I work about up 10 at a time and work for accuracy. Ussually a mid size load gets me where I want to be but no experience with that powder.

I will only be using the Berry's Rn 115gr but was more curious of the descrepency between the Lyman's and Hogdon's data.

Well I went today and shot the rounds that I loaded and I still have all my fingers. I found the biggest tree and hooked my arm around to fire the first one. Just kiddin it was pretty much uneventful but I have a few questions on what transpired. I made four loads up starting with 3.8,4.0,4.2 and 4.4.

3.8--90% of the time, it wouldn't eject the round. Basically a single shot 4.0--same thing but a little less, about 80%
4.2--it would fail to chamber every 3rd shot or less, round would jam when it tried to chamber. Also it was stovepiping like crazy
4.4--ran fine about 98%, 1 out of 10 I believe stovepiped or chamber issue, can't remeber.

So I'm pretty happy so far, learned a few things. Is the fail to chamber or stovepiping a charge weight issue or could it be my OAL 1.35-1.37. Might try 4.5 or 4.6 but I have to look in the book since I can't remeber whats the max with HP-38 with shooting plated. Also I noticed that the outside of fire4arm is a little more dirty then I rember shooting with factory rounds. Not terrible but did notice it haven't taken it apart to clean yet. Any clues to why the above mentioned issues arose?
