I thought you used these components, did you just use the data on Hodgsons site, 39.7 to 42.7gr's? And should we load in .3gr increments? I'll probably start with once fired Hornady brass, then use the Lapua. How many loads are people getting with these 2 cases?

I don't know the max that would depend on pressure. I am going to use SRP brass to thwart off those pressure issues. FRBASEBALL had the best load I have seen printed out on paper. It was a Hornady case with berger ar hybrid. I do think it could be replicated using the ELD. I think .3 grain increases are safe. I would also try other powders besides H4350, it is a great powder but hard to find it seems? I posted above on what powders have been mention in this thread and what I have seen that works. |

I'll probably start with once fired Hornady brass, then use the Lapua. How many loads are people getting with these 2 cases?  What seemed routine at 600 and 800 is a challenge at 1K, so my advice (as a new long-range shooter), is to ensure you're DOPE and fundamentals are good. I've hit at 1K with an elevation and wind call, then shot the same hold and missed by a foot so, keep at it. Also, in my reading, I can't recall a load performing at 500 yards that isn't performing at 1K.I'll also say that I'm terrible in that I buy stuff just to try it. Here's my bullet inventory: 
I'll waste my time developing a load for each across using several different powders and brass, just because I can, instead of finding a good combination and sticking with it. Okay, back on topic. I didn't have as good results loading hotter in my rifle. I'll go back through the data (and thanks Esstac, I like that spreadsheet layout) but I think my rifle was comfortable in the 41gr range for H4350 with the 130gr ELD-M, regardless of brass or primer. Back off topic, I thought I'd have more time to play around being unemployed, but it's hard work. I'm working like a fiend researching and applying for jobs and it also looks like I may start a Service Disabled, Veteran Owned Small Business. Hopefully this weekend I can collate some data and one of these days update the index. |

esstac-Great data, thanks! In your group pic's I'm unsure which charge is which group but from your data sheet it looks like your rifle likes the faster speed with lower SD's? 43.5 gr is a fair amount above Hodgson's recommendation.
My data with factory loaded Hornady 130 ELDm's show about 2750fps and SD's from 9 up to 31 which is odd. mette-I'll take input from anyone  I scored 8 pounds of H4350 a while back so I should be set. Also have 2 pounds of IMR4350 I may try.
D3-Yes for sure a challenge at 1K yards. One shot will land and the next will not. I am using a very small target and a larger one would help a lot. Also the 1st outing at 1K was more successful, other days it's hard to be consistant on my little 11x14 torso target. |

This seems right but you never know really, the spec can go out the window on one rifle vs another. My data with factory loaded Hornady 130 ELDm's show about 2750fps and SD's from 9 up to 31 which is odd. That seems normal, measure BTO on those factory founds, and also you could dismantle a few to weight the powder out. I bet you see some differences. mette-I'll take input from anyone I scored 8 pounds of H4350 a while back so I should be set. Also have 2 pounds of IMR4350 I may try.
Yeah I wish I could score powder like that, I have bad timing I think. D3-Yes for sure a challenge at 1K yards. One shot will land and the next will not. I am using a very small target and a larger one would help a lot. Also the 1st outing at 1K was more successful, other days it's hard to be consistant on my little 11x14 torso target. We will have to plan a meet up before it gets hot again. Maybe get a group of people and hit a long range spot. We can share info and maybe help each other out. |

In case you were not aware, Sierra also sells blems, but they do it by the pound, check them out here.
From another forum recently: "I use a lot of blems from Nosler. Before I first bought any, I called and talked to one of the guys. He told me the blems are only cosmetic, they sold no faulty bullets. A blem could be stained copper from a wash, one example is, Nosler Accubonds have a white plastic tip. Nosler made Accubond bullets for another ammo maker, and this maker wanted red plastic tips. Nosler made a big overrun of these red tipped bullets, and sold the extra bullets as blems. I've been shooting these 7mm 160 grain red tipped Accubonds for years. Another example is Nosler Accubonds do not have a cannelure. Nosler made Accubonds for another ammo maker that wanted their bullets with a cannelure. Nosler sold the overruns as blems, stating these have a cannelurer. |

Here's some additional testing from Alpha using the SRP and LRP with their 6.5CM brass. Numbers support better ES and SD using the SRP. My SRP Alpha brass should arrive Monday so hopefully I can work up some loads for the 260.

I pulled this from their WEZ. To me it seems that the smaller the target those percent would keep you on for a hit. On a 20" plate, decrease that to 10" and your off more often.  What about the 41.5 powder charge. |

They were using a 139 scenar, I just thought 41.5 could be low.
Hutch mentioned speed. So I was guessing it could be increased. As far as the SD, no sense in buying pricey brass if I can get single digit spread with Hornady brass. |

I had some time on my hands after cleaning two tOBRs, the Mausingfield, a S&W M&P Core, a M&P 22 and a M&P Shield, so I weighed some Lapua Brass. I broke out the GemPros, but I could only get one to verify zero.
My Alpha brass should be here tomorrow, so I'll probably do the same to see what I get for weights. 
I weighed the brass in grams and had a spread from 11.207 to 11.296. 
I then reweighed them using grains (told you I had time on my hands), and had a spread of 172.88 to 173.94 (one piece at each extreme).

Another casual observation, seems the Reloder 23 has a similar burn rate as Reloder 22, but with better temp stability. Looking at Alliant's reloading guide, they only suggest loads for bullets in the 140gr class.
