A hundred years ago I got a deal on a thousand Nosler 77 grainers. I tried to fire those damn things out of an SL8, a Tavor, and AR, a Robinson Arms... and now I am thinking of trying them in my latest AR. Try as I might - I couldn't get those pigs to fly! Even with a 1:7 twist (SL8 if I recall correctly) - results were lacklustre. I've read any number of guys that claim they're getting match accuracy out of them but I have never seen one myself. I seat them out until they'll just fit in the mag (max OAL). The powders I have to play with right now are 4895, 3031 and CFE223. My current ride has a Faxon match barrel that is 1:8... and that damn thing seems to like 55 grainers almost exclusively.

Would any of you guys have a pet load you'd be willing to share? I'd really like to get rid of those noslers - in a productive way, if ya catch my drift... ;)
 
I think this question would be best asked in the reloading section.

Look up the Mk262 cloning series. I believe that Sierra projectiles are used to clone 262 but it should point you in the right direction with some load development.
 
I watched Johnny and he didn't seem to have much luck with them either... I happen to be a big fan of his.
 
Have tried 77 grain lapua in lapua cases with best results using n140. At 100 meters between .5 to .7 5 shot groups with my hk sl8. Had pretty close to the same results with 75 grain Hornsby bthp match bullets. The heavy bullets really shine at 500 to 600 meters because of their bc.
 
I have tried them with the no-longer-available WC735 and managed to get astounding accuracy. Pressure was right at the top though. That powder was a tad fast for the bullet weight.
 
Maybe slightly off topic, but I was running some Barnes 85gr factory stuff the other day and it shot really well. Never seen a bullet that heavy factory loaded for mag length before. Pricy stuff though...
