    308 win reloading questions

    Ain't that the truth. Tomorrow is going to be the day that ends it all. I recrowned the barrel (factory crown really didn't look right to me) Going to the range tomorrow, with factory ammo (Serria match 168), different scope, new 3 lb drop in trigger and re-crowned barrel. If it don't shoot right it's going away. Cluck, cluck

    Well i have exceeded the 100 round mark some time ago. I realize that PSA is not the best out there. However for the price I paid for it I guess a $300 barrel would then make it a still favorite price.

    Ok, guys. I give up... Scrubbed my bore before going to range. First 2 shots at 100 yds were touching.Second shot low right about 4 inches. Third shot low left 4 inches. Cleaned bore let cool down. 4th shot right of first 2 shots. 5th shot left high. Using new rest setup (coldwell bench bags) Took out my 30 yr old Rem 700, 7mm Mag. first shot ." high at 100 yds, next shot touchting first shot. went to 200 yds, first shot low right, adjusted second shot low of bulles eye.3 and 4th shot right next to the 2nd one..Looked about a 1-2" MOA. So I know it was not me this time. Thinking of ditching this barrel and either going with another 308 or 6.5 creed moore. Anyone have a favorite manufacture? Looked at BCA, faxon, Brownells. Also, what is hand lapped boring? I know what lapping is and by hand, but the bore?

    Hope you figure it out. I used ball powder because it would compact better that rod type powder. Know that a liquid would be better but your close. If you really really want a liquid, I guess I could measure it out. Was in a hurry last night getting ready for the range today.

    Ok, just because you asked. Winchester nickle case: case weight 162.8 grs, volume 3.845 Grams Federal: Case weight 182.0 grs, volume 3.835 Grams I used H335 ball powder . Don't know what this means and I may not really care. But you asked for it so you can figure out the what, why and how come it is what it is

    Ok, guys looks like I sparked some interest. Anyway, got some Varget so I'm reloading several powders and weights. Once I get something dialed in my next step would be to measure inside case volume. Going to the range tomorrow. Hope something good come my way.

    well, I know that's the way to tell, but I did not want to measure each case with water or other liquid. I just dont have the time or patience or tools to do that. I thought I would just try the weigh first and see if it made a difference and it looks like it did for me. I guess my question to you is. Do you know how it's done? I know how to CC racing car heads but dont have a clue on brass cases

    That's a slower burning powder that I have been using. Might make the difference.

    Well, I have been collecting range brass for about 30 years now. Got about 5k cases. I just went through about 1k to find enough same size brass to reload for testing. 308 cases again the bulk of them are Federal but also collecting range brass and the Winchester nickle plated cases has the highest volume 163 gr compaired to FC at 181 gr.

    Well, took a step in the right direction last night. I weighed my empty brass for 308 and 223. You would just think that brass is brass and all the same size. Boy was I wrong. I found that most my brass was either 181gr or 182gr. found some other stuff that was over and under but got enough of these 2 weights for testing. Also weighed my .223 brass. Had stuff from 110 gr to 93 gr. Sorted out a bunch of 96 gr and reloaded some H4895. My god I found the magic bullet. 4 shots at 200 yds you could put a quarter over them all. Never dawned on me that case size matters. Yeah, I have read about it and case pressure, but it really didn't effect my shoot at 100 yds and less. Since I have started getting into long range shooting I understand this stuff matters. Will be taking more caution on powder weight, case size and bullet size and BC. Been reloading since the 70's and still learning...

    Rice bags. I got some 335 on the shelf. might load up some. Any suggested starting loads? Hodgdon web site say's 39.0 to 42.0

    According the the Alliant website the max charge is 48.5 and Hornady manual states 50gr is MAX for 168 gr bullets. Alliant data states 52gr of powder for a 150 gr bullet is MAX. I did not see and issues with primers or cases damage on any of the loads. Maybe some out there has some info for me. Thanks for the response's.

    OK, long range and reloaders. Just got back from the range after loading up some 150's and 168's. AR10, 308, 18" stainless barrel, 1:10 twist. 200yds range Hornady 168, Match, 47gr, 2000-MR, Avg 2458 fps, Hornady 168 Match, 48gr, 2000-MR, Avg 2680 fps Hornady 168 Match, 49gs 2000-MR, Avg 2714 fps *BEST GROUPS* Hornady 168 A-Max, 47gr 2000-MR, Avg 2522 fps Hornady 168 A-Max, 48gr 2000-MR, Avg 2657 fps *BEST GROUPS* Hornady 168 A-Max, 49gr 2000-MR, Avg 2703 fps Nosler 150 Ballistic tip, BT, 50gr 2000-MR, Avg 2803 fps *BEST GROUPS* Nosler 150 Ballistic tip BT, 50.5 gr, 2000-MR, Avg 2824 fps May problem today I think was high blood pressure because every time my heart beat I would move off bullseye. My groups were not what I expected from the 168 gr bullet that everyone says is the weight to use. My question is just how fast can I push the 168gr before accuracy degrades? This 2000-MR ball powder is much better than the H4895 I was using last week. The groups are much better with the 2000-MR. Is there a website that has reloading data for the Hornady bullets (I have been on there website), or some place else to look for data?

    Sounds good, but I think I found my issue. Loaded up some loads last night using 2000-MR powder. 168 gr, 47 gs of powder, avg FPS = 2522 150 gr, 50 gr of powder, avg FPS = 2580 The groups on the 168 tightened up a lot better at 200. The biggest suprise was the 150 gr nosler's. the grouping was excellent. 1 MOA at 200 yds. Best grouping ever with this gun, bullet and powder. It made me feel good that it was not the gun. Going to work on the 168 loads to get 1 MOA at 200. I think I'm on the right track now. Wish i could post a pic.
