Re: Case mouth tension and accuracy? Thanks for your responses. I went out to the range a few days ago with 25 rounds using the same components. The only difference is that I sized 5 groups using a different bushing. (.334-.330). (edit) I shot at the 200 yard mark. Components: Once shot and...
Hi, I've got the gold medal match reloading dies for my 308 and have the 330-336 bushings. I'd like to know how the case mouth tension on the bullet affects the physics of the shot. i.e. burn rate/pressure etc.
Re: 308 subsonic load components No typos, I'm shooting 208 amax in a 1:10" twist 24" barrel with 11.6 gr. of trail boss, winchester LR Mag. primers with the flash hole at 1/8" drilled. This is also at 300 yards. There are no keyholes, and the pattern is oval shaped if any. I've been...
Hi, I'm trying to find out a different way to do case prep and would like to hear your feedback on what you've found to work. So far I've been very successful drilling out the flash hole to 1/8" and using winchester large rifle magnum primers with trail boss of course. The brass I've used so...
Re: Standard primers versus match and BR prmers I actually shoot better with the cci 7.62 military primery then the cci bench rest primers using my .308 it goes from moa to sub moa. br2 at 300 yrds is moa w/ 3" groups 7.62 military primers @ 300 yrds is about 1-2" groups.
Re: Trail Boss Corrosive? After I noticed the rust in the first place I cleaned the entire rifle very well and the next day I did again. I thought I saw some pitting in the muzzle area but I ran the bore brush through a couple more times and it cleared up. Then redish orange rust in the...
I'm testing corrosion that Trail Boss causes on some steel nails. Sorry about that... What I'm doing is putting steel nails into 2 jars. I burned a good bit of the trailboss in one by pouring it in and lighting it with lit paper and then added 0.5 mL of tap water to both. I'm judging the...
Re: Trail Boss Corrosive? I'm going to test it in a mason jar with some copper, brass, steel, etc. I'm going to hang the metal and burn the powder in it and wait to see what happens. I'll be back with somepictures in a week or so.
Re: Trail Boss Corrosive? I found the rust along the walls of the bolt area and on the back of the bolt shaft near the knob. It was just a light rust but nonetheless it was there. I just hope that my bore wasn't effected. I shot one or two rounds and didn't clean it for a weak or so.
Hi, I noticed rust in the inside of my action today and the last and only thing i shot was rounds using trailboss. Did/do you know that IMR Trail Boss is corrosive? I went on a google search and found this on my first look... http://www.theopenrange.net/forum/index.php?topic=6150.0 Tell me what...
Re: Powder for 178 amax in 308. Wow that's a lot of powder. imr 4064 45.7gr... that's a compressed load. What length and twist barrel are you shooting with. I have a 24" 1in10" twist rate and am shooting 43.0gr imr4064 and am getting 2650+/- fps.
Hi, I'm currently using 43.0 gr. of IMR 4064 for my 178 AMAX rounds with winchester brass, cci military 7.62 primers. I get sub moa. What experiences do you have with different powders or whatever you use?
Re: 208 AMAX in .308? Y or N? What about subsonic then? If supersonic's not good for the 308 then shooting sub with a can should be good right? Thanks again for your input.
Hi, I'm going to start loading 208 AMAX in my rem. 700 308 and need some input. Anyone work with this bullet/case combo? What powder(s)/primers do you use? Anything else? Thanks for your help everyone.
