    Shot prairie dogs on a ranch when I was in college. He gave us permission to shoot in the pasture with the cows on the condition that we shoot any canine we saw. I asked him how I could identify his dogs while out and about so we didn't shoot a...

    Also going to try these. Got this mold as a second from LBT. It's a 200 gr 38 Kieth swc. Had a small gouge in one of the lube grooves, and I never took a liking to it as I thought I would. It sat neglected for a few years. Well, plain...

    Thanks. I like their selection. Right now I'm using the single pistol bulls because they fit my 1x red dot well. (Easy to center) and I'm shooting different bullets that have different points of impact. That target seems to catch them all...

    bld451 replied to a thread Plain Base Gas Checks in Gas Checks
    I have been crimping with the Lee F.C die. I tend to crimp all the 300 blk ammo I load. I should probably test it without a crimp to see if the bullet jumps when fed from the magazine. I presume it will since I only have about .001" neck...

    Had a little problem catching my bullets yesterday, so put some cinderblock behind the rag box . These NOE 153 HTC's at about 1800 fps went through the gel block, my rag box and broke the cinder block, but I stopped them, by gosh. Not exactly...

    I have the same question. I will be doing a initial test this week on that very bullet. Made a pretty basic checkmaker and think I might have dimensions narrowed down for the real setup. Here's how it turned out so far... Also doing some...

    I have become a fan of the Lee factory collet type. Very easy to adjust the crimp level and nearly blind to case length variation.

    I did notice some unburned powder and slightly dirtier cases with the 1680, but the 225 subs don't reliably lock back the bolt with 4227, h4198 or others I have tried. 1680 is reliable that way. I'm using 296 for the 153 supers. I have done a...

    It looks like the cutting along the leading edge of the super's rifling got all the way out to the front of the bullet. The pockets at the front of the crimp show there seems to be quite a bit of pressure getting to the front of the crimp groove. ...

    Some pistols have fluted chambers similar to the HK 91&93. Some examples would be a P7 or an MP5. There are others, I'm sure. Inspect it like any other. I load them. They are fine unlike the rifle brass from fluted chambers. I don't find much...

    Here's the NOE 153. It fared a little worse, as we would expect. Interesting, it seems there was gas cutting on the leading edge all the way along the rifling track in some places. I have really only heard of trailing edge issues. also...

    Hey there. I managed to take care of the "lead ring" problem by polishing the transition from the end of the chamber into the throat with some 1500 paper and a dowel. It was pretty sharp there and I thought I'd just break the edge there without...

    It does look pretty good. I was thinking I could get it to open up a bit more but it did measure about .560 at the widest point. I used a rag box to catch the ones that went through, so I can't say what the total penetration was. It would be...

    Thanks Hamish. Now I need to decide. Make new pins not quite as long and more tapered or try a 25-1 or 40-1 mix? Is it even worth trying if this performance proves typical? If it had stayed together, how much penetration could I expect? As it...

    I presume you will be hunting with a bolt action? If so the NOE 247 hollowpoint looks like a great choice. Pay attention to the nose diameter depending on how you plan to coat or lube them. The Lehigh and Maker commercial bullets are gaining quite...

    Here are a couple more photos... nose pieces... tracks... So... given that 300 blackout subs are about 10mm ballistics, energy-wise, choose your shots carefully. Not a huge wound channel, but at 1000 fps, you generally won't get that. Plenty...

    The MP 311-235 HP seems to be a good fit if you are going to shoot bare or with Hitek. With powder coating, I need to nose size the bore-ride section. I chose that over the NOE due to the slightly pointier meplat. Some guys are having luck...
