Have a 165 (speer btsp)and 168 (eldm)load that both shoot well and near enough same speed. Poi has the 165s sitting an inch below the 168s but both pills are getting too hard to find or no longer come into NZ(i believe). I also shoot factory corelokts but they shoot 2.5-3" lower than my main loads. Would reloading 150s at a higher speed bring them up to the same POI as the other two or not that simple?
Unlikely but possible, a very few rifles will print a variety of loads at the same POI (usually at fairly close range like 100) but remember thats not so overfull if they have different trajectories because at any extended range (250M Plus) they will be miles apart . . . . not worth bothering with in my opinion.
I'm with Tentman, never quite seems to work out for me that type of thing...
Ok not sounding promising. May just shoot my factory ammo then re zero with my main loads. Won't bother trying to find corelokts. Any cheap 165 suggestions?
I use Bryns Targex 165's, they shoot amazing (1/3 MOA in my rifle), they are supposed to be OK for game but I only shoot paper and gongs with them.
Nnothing wrong with the 150/ 165 SGK's. You can get 2750-2850 out of 150's.
And while I remember - I follow Mule Deer's (the writer John Barsness) 308 load philosophy - take a 150 to 165 gn projectile, stick 46.0 gns AR2208/Varget and go shoot it, 99% of the time its a winner. I haven't bothered working up a 308 load for years using this approach (if going straight to 165's it does pay to try a 45.0 then 45.5 first to ensure you're not hitting pressure). I get 2740 fps with Targex 165's in my 22" 308 with superb accuracy as mentioned, its a warmish load.
Seems a pretty fair approach @Tentman. I reckon we all over think it.
Any standard 150 to 165 gr bullet intended for hunting will be fine.
Plenty of 168 Amax about, problem solved.
Plus 1 for the 168gr amax. 165gr ssts do the job too!
Yeah how similar do they shoot to the eldms? I am aware they are almost identical bulletsQuote:

Hi, seems like the right thread to ask..
I use 308 in 150gr 1:10 twist shooting out to 400mtr no problem, but am thinking of moving up to 165/168 gr , will the heavier weight pill give me more legs and tighter grouping as I'm hunting more tops ?
Try 178 grain eld-x @2600fps.

By fiddling with the velocity I could get the 165 and 150 grains to shoot to the same elevation at 100 but the 150 grains shot left. Recently I ran some tests with 125, 150 and 165 grains and different powders that produced similar results. Longer range would just make things worse. My 6.5x55 and .223 rifles tend to shoot different projectiles close together. These days with better scope adjustments different loads shooting to different POI is less of a problem.

Yup. What @Woody says.Quote:

had the same off to one side issue going from 357 mag to 38 special in the marlin lever . 38 went to the left around an inch and a half or so at 25 mtrs when sighted with 357, but strangely after fitting a suppressor it stopped doing it and now both rounds shoot straight ( height differs though obviously ) . just use the hash marks in the scope for elevation going from 357 to 38 now.Quote:

My Sako 85 loves them, but can't achieve the magic 2600, what length of barrel & powder are you using?Quote:

The data here is developed for my rifle and you woukd need to work up a safe load carefully for any other.Quote:

Recently I tested 125, 150 and 165 projectiles in my now suppressed .308 and found that the 150 grain projectiles shot left of the other two even at 60 metres. I believe that you may have better success sticking to one weight, as close in BC as possible. The BC of the Corelokt is much lower than the two other projectiles you mention so would likely shoot lower. The factory loads will likely give less velocity as well. Its always best to get your premium load sorted first then tinker with any other load to get it to match. In my rifle an extra grain of powder would put the Speer projectiles in with the ELDM's. This is assuming you are not max already.

Ok so updating this thread. Have ditched the speer 165btsp and loaded the speers 165gr HCSP(federal blue box bullet). 45gr of 2208 loaded to 2.75" coal has these shooting sub inch @ 100m with the same POI as my remington corelokt factory rounds then by using my ballistics calculator worked out my 168eldms are zeroed @ 250 so pretty happy. Need to shoot the speers at distance to verify speeds but guessing 2600-2630 which means they are good on reds/rusa size animals out to 400m~ which will cover basically all my hunting.
Cracked it then. Well done.Quote:

Already sold mate. They are back in stock at reloaders thoughQuote:
