6.5 140 Solid Base weight variances

[rjm158]

I didn't want to hijack JD's thread on the 308s so I started this one. I loaded some 6.5 Creedmoors using the seconds I got from SPS. As with the 308s, I weighed a handful and found one that was under weight at 139.9 and the rest were over weight at 140. 5, .6, and .7.

These are seconds so I don't expect them to be perfect. As long as they will shoot accurately, I have no concerns about their performance on deer. I'm hoping to get to the range tomorrow and see how they do.

Looking forward to seeing how they shoot. They seem like great soft point bullets for the money.

I just received three bags of 6.5 140s and have not checked weights yet. Cosmetically they seem to look good and cannot wait to load them for antelope and deer. I will weight sort them merely to see the variance. I’m excited to run some 140s in my 6.5x284. 125 partitions have been a hammer but are hard to come by. I won’t take shots over 500 yds partly because the wind always blows in the high desert of WY. If 140s will cut the wind a little better then it’s a bonus.

I made a range trip yesterday with family to get rifles ready for our deer season that opens this Saturday. I have to say I was disappointed in both the 308 and 6.5 Solid Base accuracy. Both shot in the 1.5-1.75 realm, and this was from proven rifles. The ballistic numbers were good so I can only speculate the weight disparity might have contributed. They would have sufficed if there were no other options, and you kept distances to 100-125 yds.

Well that is perplexing. I am a ways out from testing anything. I will get the lot weighed this weekend and see where my variance is. Thanks for the update and sorry the results were not better.

So I was able to take time this afternoon to weight the three bags of 140gr solid base that I received from SPS. I have a fairly crappy digital scale that doesn't show tenths of grains. I weighed each one and if 140 populated, I set it into a pile and tallied it. If it came up differently, I set them in separate piles based on weight (139-141). Then I took each bullet that didn't match and weighed them individually on my bar scale (I use this for all powder measurements when loading) so I could get tenths. Long story short, from 150 bullets, I came up with a total of 11 bullets that were either under or over. I had five that came in at 139.7-.8 and five that came in at 140.5. I had one that touched 141.0. Obviously, I should repeat the process with a digital scale that reads partial grains, to confirm exactly what each bullet weighs. I don't shoot match and I think at the end of the day for hunting purposes results should be good. I have not shot any of them, so results may vary. My 6.5X284 has not had accuracy issues with anything I've fed it. I will start with a previously used recipe for 140 Partitions and see where they print. I may see some different results going from a flat base to a boat tail but would expect that to be more vertical than anything else.
