So then tuning comes down to bullet weight and powder? I guess you do have some variations in OAL to play with, and stay within mag length.

OK thanks. Good to know it's not me or my rifles.

I've tried measuring several AR15's with the Hornady OAL gauge to determine where the bullet contacts the lands. I don't have the curved version for semi-autos, but I am using the straight version, the one for bolt rifles, and simply removing the bolt carrier. I am getting some unreasonably...

Thanks, that's the info I needed. "No, The full metal jacket and the PD or XTP are different bullet profiles." I've read that several times and I'm not exactly sure what titegroup tiger meant by it. Naturally any FMJ and JHP are different profiles. Not sure how he is using "PD" in this...

By "their" are you meaning Precision Delta?

The data came off Speer's website and is for their part #3993 (FMJ) and 3998 (GDHP). I printed out the data file and have it in front of me and it shows 4.4 is max. I agree this sounds too hot to me. Their OAL recommendations fall inline with what you are saying. See my post above. They...

Yes, I thought I was given 115gr info also, but looking at Speer data for similar bullets they are showing 4.0 to 4.4????? In looking around the forums I've never seen a load that high. So 4.1gr would work in the PD JHP or the FMJ? I would like to start as low as possible and work up. Would...

I've been reloading PD 124gr 9mm JHP and FMJ for a long time using WW231. I've just bought some Titegroup and need to work up a load. Of course none of the manuals are going to list PD bullets so should I just use other comparable bullet's data and COAL. I called Hodgdon and was told 4.1 to...

In your example I understand because after cutting off 1" at the base, the pyramid will drop "down" in the cutout, leaving new space on the sides. However with the sight, since it sets on top of the slide, and will not be allowed to drop "down" into the dovetail, I can't see where you are going...

JT & RC: I've got a source on Delrin so I'm going to make some punches regardless if I use it on this project or not. Yes this makes sense. But, if the base of the sight is wider than the dovetail on the slide, I can't see it dropping down into the dovetail. I realize filing on the...

I trust you (and the others who give the same advice)! I noticed in your other post you said you made your brass punches out of brass rod. What are good sources for small quantities of brass rod? I can find brass punches and sets but would like to make my own. Also, to change the...

Well, I knew brass was soft but I still though it might leave scratches or dent the sight. Maybe, as insurance, adding a little masking tape to tip of brass punch. A video on Dawson Precision Sights website shows Mr. Dawson using a nylon tipped punch. Looks great but trying to avoid the...

I'm getting ready to do an sight install on a Glock. I don't have a nylon punch so I'm considering building a punch out of wood dowel or possibly using a piece of Delvin rod. I've never used Delvin for this application but seems it would be easy to shape and I'm feeling it would not scratch...

Shifty, Careful with those BB guns............you'll shoot your eye out!!! I cringe when I think of the stupid things we did with our Daisey Red Rider BB guns. With old age I'm much safer now and much more concerned with keeping my eyesight. With that said I feel you are right about the...

I have been using some Oakley ANSI rated clear lens when at the range. I know glasses with this rating would probably protect me from almost any thing that could occur, but I'm still thinking it might be time to get a little more serious about eye protection. I have discovered that Wiley X...
