Greetings. I have worked up a load of H1000 79 grains under a 180 gr hornady btsp. It sometimes prints very well but sometimes spreads out to 1-1/4 moa. Same shooter same set-up. Could be the shooter or maybe it is not on the edge somehow. A half grain more or less than 79 grains prints 3” groups at 100 yards. But this will have 2 or all 3 touching. I bought some 208 eld bullets. I see a lot of you use them. Are they more stable or flatter shooting at longer distances than 180 gr? They have a BC of 690. Whereas the 180’s have a BC of 475. I appreciate all input and advice on this. Thanks.
