Is there a noticeable difference in regulation if I load 285 gr bullets for a DR factory-regulated for 286gr? Sorry if it's a dumb question but I am slowly learning the art of reloading and shooting a DR! Oxon | ||

Not even several times one grain. | |||

Above posts can be true. However, sometimes even different bullets of the exact same weight will not shoot to regulation. Case in oint my 450 No2 with the same powder charge will shoot 480 Woodleigh Softs and Solids, Swift 500gr A Frames, and Hornady 500gr SP and the old style Solids into the same group at 100 yards. The encapuslated brass solids they made for a while would not. They shot terrible. DOUBLE RIFLE SHOOTERS SOCIETY | |||

I expect one grain in bullet weight will have little effect on regulation. Bullet shape however may impact things greatly. It has been my experience that the smaller the caliber the more influence bullet shape will have. Working up loads in my 7x65R gave me fits. My rifle was regulated with 156 grain Oryx ammo and duplicating that load took quite a bit of work. I ended up placing all the 7MM bullets out on a table and noticing the differences in shape. The bullets that had a common profile with the Oryx ended up being the easiest to load for simply because the regulated at the factory velocity of the Norma ammo. Other bullets required more or less speed to shoot best. Just my experience so take it with a grain of salt ****************************************************************** R.

One grain of powder can make a difference though!

Correct! One grain of powder can make a lot of difference, but one grain of bullet weight is not likely to make a difference,though I'm not saying that it absolutely cannot happen. I suspect the bullet shape, and hardness of a bullte the same weight would make far more difference than one grain of weight. ....Mac >>>===(x)===> MacD37, ...and DUGABOY1 DRSS Charter member "If I die today, I've had a life well spent, for I've been to see the Elephant, and smelled the smoke of Africa!"~ME 1982 Hands of Old Elmer Keith  | |||

I have found that one grain of IMR 4831 makes no difference in regulation of my 450-400 at 50 yards; it took 3 to move the bullet, but that is a slow powder. As for bullets, as long as they are 400 grains, they shoot exactly the same; even swaged down .416s perfomed the same as Hornady DGXs, DGSs and plain .410 soft noses. in my gun. | |||

I would say that powder weight and bullet seating depth would play a far bigger roll in regulation than a few grains of bullet weigh. ND Stephen Grant 500BPE Joseph Harkom 450BPE | |||

It's not your inexperience. It is instead the weirdness of rifles generally. No one ever knows what will work best in any given rifle in any configuration until testing is done. The results often make no sense at all. But all of us know that this is true. It only took me about forty years to figure this out. Glad you're getting there more quickly. | |||
