That looks like a cruiser rifle the precursor to rail guns in the unlimited class.

The red dust coming off the old powder as well as a vinegar smell is due to nitric acid a breakdown product of the nitrocellulose in the powder. I have known where a can of old powder spontaneously combusted when it got to this stage. I have only had one very old can of powder like this. I...

Dear Bill, The origins of benchrest date back to pre-history as evidenced by the cave paintings found in Pennsylvania, a state where cavemen are rumored to still exist. These ancient drawings depict groups of hunters brandishing sharpened sticks. Some of the hunters had more than one stick. One...

I think I found an answer to my question about 205M vs 205MAR primers. Two sources cited a difference in primer cup thickness between the two with the 205MAR having a thicker cup. How that would impact short range benchrest accuracy is an unknown to me.

On the subject of primers: A number of years ago I purchased a case of 5000 Federal 205M primers. The cardboard box they came in listed them as 205M. When I opened them recently the boxes of 1,000 and the individual boxes of 100 primers were marked 205M AR15 primers. Does anyone know anything...

Jackie you are the original "Look up in the sky! It's a bird. It's a plane. Wait. It's not superman. It's Jackie sailing through drag strip timing lights, over water, without any attached device, even perhaps into outer space. I am jealous. I always wanted to fly. I got to know. Did you have...

Dear R, If you need to further clean your trigger and cannot disassemble it you can try cleaning it in a small ultrasonic cleaning machine. If you don't have one, see if you can use a friend's. Despite your budget constraints small US units are cheap and you may consider purchasing one if...

One thing to remember when switching springs is the ID of the spring. If it is too small the spring may bind when compressed. If it is too large the spring may bow to one side when compressed and rub against the inside of the bolt. I am not an expert on this. Perhaps someone with more expertise...

I recently replaced my plastic railgun points (pins) with the ones from PMA. Here are a few things to know: 1) The points are very slightly larger than 0.5" in diameter. They are an easy press fit into a 0.5" hole. I did not use any adhesive when installing them and so far they have remained...

I have seen that Lab Radar has come out with a unit similar to the Garmin for $600 and that Garmin has come out with a cheaper Pro Compact unit for slightly more than $400.00. I haven't tried either of this units and hence cannot comment on them.

FYI: I talked with the Lab Radar folks on the phone last year. I had found out that the LR unit will only read up to 3,999fps. I asked them if the unit could be modified to read 4,000+ fps or did they plan in the future to market a unit that would. They responded no to both questions. I did not...

I forgot to mention groove numbers. I use 4 groove. Others use 6 groove. I don't think there is much difference in accuracy between the two. It seems to be based on personal preference.

Dear GN, From reading the equipment lists of the matches it seems that Bartlein and Krieger are most often used for 6mm barrels. Twist rates usually vary between 13-14 twist. The blanks are expensive and the wait times are long if you order from the manufacture. You might try places like Bruno's...

You can also use a product called Cerrosafe. Put a clean patch on the end of your cleaning rod and push it from the muzzle end of your barrel until it is just about to the front of your chamber. Do not push it into the chamber. This is to prevent the melted metal from running into the rest of...

I have also heard that the moving backer had broken/stopped moving. The record committee decided to award him the record anyways. I in no way want to imply that cheating was involved and I believe that Mr. McMillan did fire 5 shots into the group. It was a hell of a great group and stood for...

I only have experience with Jewell triggers for benchrest rifles so please take this into consideration when you read my advice. A couple of things may be causing the trigger not to reset. One is grease or oil on the sear surfaces of the bolt and/or the trigger. Another is a weak trigger return...

I run them at 125-250 RPM. I drill and straight bore first (I do not have a taper attachment)

Dear Rflshootr, I have used both HSS and carbide reamers. I prefer my latest reamer which is a 6PPC .268 nk. carbide one. I find that I don't have to run the reamer at 1 zillion RPM to get a good finish in the chamber. The one downside to a carbide reamer is that pesky wire circle clip used to...

Dear JWV, It is my opinion that humans will actively seek out pleasurable substances or actions be it Fentanyl, love, religion, marijuana, ethyl alcohol etc. From a medical standpoint I think marijuana is probably less harmful then many other drugs such as alcohol and certainly less harmful...

One of the developments in the study of mental illness that has been of the relatively recent inclusion of and study of sociopaths and psychopaths. These are groups of individuals with a common trait of a lack of empathy towards other people. We used to call them mean people or other names...
