There is a lot on here that i agree with, what Joe and Charles have said, and more pertinent to me, what Lynn has said about the 107 SMKs. Just this weekend gone i tested two different bearing lengths head to head in my 6BR light gun where the longer shot a 6.1 and the shorter shot a 4.1. Now...

I will stick my neck out here and say that the projectiles are the Australian BJD 155s.

I know some of you are going to say that i should be asking BAT machine this question, but i thought i would ask here first in case there is someone who has atempted this modification. I have for some time had in my possession a RBRPRE BAT M action. With the view to use it as a 1K action, i...

Depending on which method is used for the mounting of the barrel, i would say that the difference could be between investment casting and machined billet. For a barrel block arrangement, the action is just a delivery system for a firing pin. So it could be said that any action could be used. If...

Bob, this particular 6BR, and only this one, gave me the vertical heebee geebees. Yes it cured it, but the pressures rose a fair bit where max loads were about one grain less than what i had used with the SR primer. Only regret is that i did not try the small flash hole first up. As i said in...

My apologies Charles, been away from the forum for a bit. As i only intended to do a small number for a trial i simply set a sizing die in the four jaw chuck of my lathe and just lightly tapped in each case. The friction there was more than enough to hold each case. To do the reaming, all i did...

If you all recall i posted about Jeffs bullets a little while back. The humidity for the day was 63%, or about average for this time of year. No other bullets shot from other shooters rifles showed the trails or puffs. What you see on the youtube video is a distortion of what is really...

Bloody outstanding, for both group and score six match. Tony Z.

Just thought i would throw this one out there and see where it goes. There has been a mention made of the "clean burn" or something akin to a point of efficiency where all things work like what has been compared to the inside of an internal combustion engine. Now in the small case like the PPC...

Charles, yes i did take the flash hole out to 80 thou before i reamed the small primer pockets. If it did make any difference, i didn't see it. The cases reamed out to LR had the flash holes taken to 80 thou as well. Never did try LR and small flash hole. I need to say that i have had quite a...

Today we shot our 1K match where i sat behind aJR of Aus and watched him shoot his second HG card for the day. Now the fifth and eighth shot left a blue smoke burst some fifty yards from the muzzle that didn't continue on with the bullet further downrange, just seemed to jet out a plume and that...

Here is my two cents worth. From what i have seen of my own and others combinations, when it comes to small primers and some cartridges, there seems a need to go to the 450 mag primer. Now that should tell most of us that all is not well. I had a 6BR once, it showed plenty vertical at long...

I would question the accuracy of the chronograph. Sudden spikes like this are common outdoors, on the chrono that is, not the rifle. Also where did this "fast" shot strike in relation to the other shots on paper?

I had forgotten about that. I can recall when i was at our sniper school when the Aus army was looking at replacing the aging old Mark 4s and the Steyr SSG was there and i remember clearly that when it rained and the cartridges got wet, the rifles impact was completely different. Not 80 cm at...

The original poster of this thread asked on another forum why Woody didn't manufacture a Rem 700 footprint action free of royalties for the market in Australia. Stocks are available as are triggers, bases etc. That would have made sense as it fitted the requests of varmint, BR, tactical and...

I think to take an action designed specifically for prone Fullbore or FClass and test it at the short or long range BR disciplines is not really a test of anything more than the ability of the shooter to overcome the inadequacies of the design. What arena does the INCH want to be known for? Jack...

Trev, you wanted some opinions............. Compression of the bolt, for some reason seems to be the one area many people seem to drift to when it comes to rear locking actions. This is not the problem these sorts of actions have. The reason that the Rem 788 is prone to pressure increases...

The reason i threw 410 into the mix is that i strongly suspect that there are barrel makers using it and have done so for a while. Cryo or other treatment processes cannot explain away the vast difference in threading and profiling machining that i am seeing. Some threads cut clean and swarf...

410 maybe?

Just got off the phone to Jeff Rogers who told me of this outstanding group. I asked Jeff if it was the Bibs and he didn't know then but Dave has let us all know it was. Congratulations on a great effort Joel and a fine result after a lot of hard work. Was it the tube gun? Because if it was...
