So it's been about 3 months since I told @.Steve. I'd post load info/data "in a few days". But here goes...

I keep fairly detailed records of my load data in a load log, including chronograph data; velocities and extreme spreads. I also note group sizes and the range at which they are fired, POI's at different sight settings, etc. But once I log a particular load a couple of times, that's it. The numbers aren't going to change as long as the components don't change and if it's an accurate load, it's an accurate load.

I do however snap photos of most all of my groups. All of my firearms have their own folders on a hard drive on my computer. In the folder I keep photos of the groups and label the photos with the load information. I find it more enjoyable to review loads and groups in photo form than poring over numbers in a load log.

So, I'm going to post photos here of groups in hopes that they might help someone. First a few points-

Obviously, this data works in my rifles, but work up to the loads, and use them at your own risk.

My shooting range is at my house and I stopped shooting paper targets some time ago because of the expense, keeping pasters, keeping staples in the staple gun and the mess of targets blowing all over the pasture and wooden target boards splintered to smithereens. I now shoot steel about 99% of the time. To that end, some of the 100 yd. groups are a little difficult to decipher as the cold-rolled steel target is pock-marked from being shot with those nasty jacketed bullets and the same with my old 200 yd. gong. I just recently built a stand for a 12" AR500 gong to use at 100 yds. and replaced the cold rolled steel 200 yd. gong with a piece of AR500. Much better.

You'll see a lot of photos of loads fired from an Iver Johnson Carbines. This rifle is the least valuable of my carbines and therefore is the one I use most for chronographing and testing loads; it's the guinea pig of the bunch. Fortunately it's also a reasonably accurate rifle. I also test loads with a 1st Generation Universal; I know, heresy, but it saves wear and tear on my original M1's and it's quite accurate too.

You'll also notice that most of my loads are with cast bullets. The combination of bullet scarcity and the realization that cast bullets are as accurate, and in some cases more accurate than the Hornady 110 gr. FMJ's I'd been loading led to this move. Bullets cast from the RCBS 30-115-SP mold, a 116-118 gr. RN, have a profile very similar to the Hornady 110 gr. FMJ and any load used for the jacketed bullet will yield very similar velocities with the cast bullet, and trajectories, at least to 200 yds., are very similar, although some carbines can be quirky with trajectories with cast bullets. (***A note regarding AL 410- Many handloaders are using AL410 as an alternative to AL2400, HOWEVER, there is no published data for for centerfire cartridges with this powder. I've recently been using AL 410 with cast loads with great success. HOWEVER, I have NOT tried it with jacketed bullets.***)
I recently began casting a bullet from the discontinued Lyman 311576 mold. This is a gas-check bullet that weighs 125-128 gr. and shoots very, very well, as can be seen. So far I've only run it a shade over 1850 fps and it shoots a bit low at 100 yds. with the 100 yd. sight setting.

Finally, if you have any questions regarding the loads, etc., fire away.

Iver Johnson-







Inland #791609 from RTI-





More to come later.

Default Accurate #4100

A few weeks ago I found Accurate #4100 in stock at MidSouth, so I snagged a pound of it to try out.

All loads used LC72 brass, Wolf SRM primers and Hornady 110 gr. FMJ bullets seated to 1.680"

It's a very...."energetic" powder, to say the least.

14.0 grs. - 1966 fps/ES- 9 fps (IBM Carbine)

14.5 grs. - 2034 fps/ES- 38 fps (IBM Carbine)
14.5 grs. - 1985 fps/ES- 40 fps (1st Gen Universal)

15.0 grs. - 2044 fps/ES- 38 fps (IBM Carbine)
15.0 grs. - 2088 fps/ES- 20 fps (Inland Carbine #791609)
15.0 grs. - 2025 fps/ES- 45 fps (1st Gen Universal)

A few random thoughts-

- The Western (Accurate) Handloading Guide No. 8 lists 15.5 grs. as the maximum load with this powder and the Hornady bullet, generating a whopping 2164 fps. I may try this load later, but really don't see much use in it unless I decide to go after some hogs with a Carbine, which is possible.

- Western powders "Ramshot Enforcer" and Accurate #4100 are one and the same and data is used interchangeably.

- I'm out of Hornady 110 gr. FMJ's, so I wasn't able to do as much accuracy testing as I'd like. If anyone has any of these, or actually any commercial (Hornady, Sierra, Speer) 110 gr. FMJ's they'd sell, shoot me a PM.

These are the only groups I recorded. My MO is to load 15 rounds, run five over the chronograph, record the results, then shoot five at 100 yds. then five at 200 yds. But occasionally the chronograph is uncooperative, requiring an extra shot or two to get a 5 shot average. Such was the case here and that is why the 200 yd. group is only four shots.





I really think the 100 yd. group was strung vertically due to operator error and look forward to trying this load again.

So that's all for now. Next I'll probably test some cast loads, so stay tuned.
