    how does bullet shape affect pressure?

    thanks everybody...its starting to make sense now. the discussion i was having was in regard to a fellow shooters custom loads he recieved after sending his gun to corbon. in 20 rounds, the majority had flattened primers and a few even blew the primers out. he noticed it when he almost...

    how does bullet shape affect pressure?

    I had a discussion with a fellow reloader who told me that the shape of a bullet directly arffects the pressure in a gun. He said that regardless of the seating depth, some bullets crewate more pressure than others. The bullet we were talking about was a barnes ttsx. Can anyone explain this to...

    .308 Win. question

    walteray, what kind of velocities are you getting from your 20" barrel? anywhere near 2700? i started my testing yesterday for my 20" .308 using varget. although, i am using a 168 amax, i believe our bullet selections are fairly similiar. i was only recieving 2550 f/s with 98% of max load...

    new problem with bullet seating...help

    Farmer buck, I did measure the whole box...the average was .3085. That is close enough as far as I'm concerned as I'm sure only a couple threw the average off. Not a big deal, still a good product. Jimmyk, I agree. I am a firm believer in rwading instructions, but if you don't trust your...

    new problem with bullet seating...help

    Thanks 918 and jimmyk... I believe you helped me solve this...I hope I should've followed my gut on seating die adjustment..I knew better, but I followed the instructions. After talking to chris at redding he told me to disregard the instructions and set the die as I have with all my other...

    new problem with bullet seating...help

    i was screwing it down until the stem bottomed out against the die...? just talked to redding and they are sending me a new stem with a smaller opening for the tip of the bullet so i get more length on the stem. have you had this problem with this bullet and this die?

    new problem with bullet seating...help

    I rechecked the die... it was run down to the shellholder and backed off a full turn. That is exactly how the instructions say to do it. I checked that this was correct by running an empty case into the die and it came out fine.

    new problem with bullet seating...help

    you could be right...but i doubt it. i already tested them on some smk's and they all miked perfectly at .224. that still doesn't explain why when seating they cause my case to buckle and collapse. the expander ball measures .307 but after sizing the case neck only measures .304-.305...

    new problem with bullet seating...help

    i screwed the die down to the shell holder and backed it off a quarter turn. yes, i have the plunger in the die and it is adjusted correctly. i could be off base but, normally the bullets are the correct diameter and you size the case neck slightly smaller for a snug fit and good neck...

    new problem with bullet seating...help

    i was seating some 168 gn amax today in some hornady match 308 brass and the bullets would compress and ruin the brass towards the end of the press stroke. i measured the bullets and the measured .310 and the neck of the brass is .305 after full length sizing with my redding dies. i've...

    Hornady Concentricity Gage

    You can fix the ro on some bullets, but not all. Sometimes it makes the problem worse if you're not careful. It takes a bit of practice to effectively use this tool. There are many variables to how well it works like crimp and seating depth. The sinclair tool just measures, no bells and...

    Hornady Concentricity Gage

    roc1 i purchased this tool because i thought it would solve all my problems...wrong. like the guys said it just shows you there is a problem, but not where it is. it is more of a band-aid on a bullet wound. i tested some of my .270 hunting rounds that i loaded some time ago that i had...

    question of velocity

    thanks jimkirk, my gun is also a 16" dpms "sweet sixteen" with a bull barrel. i will try the workup that you described. if my gun doesn't like the pressure or i can't seem to make it shoot as accurate, i know i have a moderately fast and very good grouping load already.

    question of velocity

    i was thoroughly suprised by some results that i obtained today while testing a load. i have been working up a load for my 16" barrel ar-15 using a barnes 50gn varmint grenade and reloader 10. the barnes book calls for max load of 22.2 grains with a velocity of 3202 f/s. my load...
