    What's the deal with Tikka?

    The Ultimatum defacto would be my goto to open up more trigger options but unfortunately you don't have the option to order one without a trigger so you are stuck with trying to sell off the TT that it comes with.

    Need help with Impact action.

    Sliding over the top should be related to the mag catch not holding the mag high enough or the feed lips need to be opened up to let the round sit higher in the mag. Although it being the second to last only is a bit confusing. Only think I can think of is cycling the bolt slowly pushes the mag...

    APW Expander Mandrel Set

    What are peoples thoughts on this: https://www.impactproshop.net/product-page/apw-expander-mandrel-set Greatly reduce your ES and SD with this expander mandrel set from APW. The set includes the following mandrels: 224Cal 0.223 0.227 243 Cal (6mm) 0.243 0.245 264 Cal (6.5mm) 0.263 0.267 284...

    Super 6 Action feeding problems

    I don't have a super short 6 but I have had mag feeding problems with my rifles and people will be better suited to help you if you provide more detail or better yet pictures. Is it hitting the feed lips or back of the mag with upward pressure, sliding over the rounds, bullet tips getting caught...

    Whats your SD (PRS/ELR)

    Yea, for close range you will need to get creative or get one of those fancy electronic targets.

    Whats your SD (PRS/ELR)

    I suppose the proper way to look at is that it will matter less percentage wise but will still matter some BUT you as a shooter need to decide if your time is better spent shrinking a .65 MOA rifle to .45 or to go out and learn to read the wind/practice positional shooting with that .65 MOA rifle.

    You can lead a horse to water but you can't make him drink.

    Whats your SD (PRS/ELR)

    Unfortunately the cone of fire of a rifle is also a normal distribution and is subject to the same issues as muzzle velocity tests. Edit: But I do agree on letting the paper tell the story, just with a larger sample size.

    Whats your SD (PRS/ELR)

    And SD of 4 isn't actually an SD of 4, it is an SD of 4 with X% confidence of being between [X and Y]. You can end up with the correct conclusion with a confidence of 10%, approximately 10% of the time... Edit: I gave examples of actual values earlier in the thread with different confidence %...

    Whats your SD (PRS/ELR)

    What do you mean. If you give me a set of numbers I can give you the stats including confidence intervals for the set.

    Whats your SD (PRS/ELR)

    I have come to the conclusion that some people just refuse to try to understand the math behind something. We really shouldn't be measuring group sizes with ES either, it is a bit more difficult but we have apps that should be able to tell you the SD of the distance of each bullet impact from...

    Whats your SD (PRS/ELR)

    It all depends on the actual numbers. If you are consistently getting 2’s, 4’s and 5’s then that means you have a large sample. Every statistic someone provides should come with confidence intervals to better represent the data. The worse the actual SD, the more likely you are to get bad results...

    Whats your SD (PRS/ELR)

    I like how you dismiss mathematical formulas about statistics and probability with the same confidence a flat earther dismisses the earth being a globe.

    Whats your SD (PRS/ELR)

    There are calculators for confidence intervals, like what I posted earlier: Avg Confidence Level of 95% = 2812.9747 ± 0.911 This means that you can be 95% confident that my average MV is between 2812.0637 and 2813.8857 The same calculation can be done for SD's. So if you end up with: 41...

    Whats your SD (PRS/ELR)

    It was a Brux in Accurate Ordnance Sendero Contour. I just told them to chamber it for the 140 grain hybrids. My notes from that day say: Flash Hole Deburred, Primer Pocket Uniformed, Trimmed to 1.910", Deburred, Chamfered, Neck Turned .014/.0145", .290" Neck Bushing, CBTO 2.190"

    Whats your SD (PRS/ELR)

    I don't think I have data for colder/hotter temps with this rifle/load and the barrel is now a tomato stake. Sadly my wrists are just getting worse and worse so I don't do any reloading and very little shooting. It is what it is.

    Does this make you horny baby? (Not that it rly matters but this was 40.4 grains of RL16 in 6.5 Creedmoor Lapua SRP Brass , CCI400 Small Rifle Primers, Berger 140 gr Hybrids) Bunch of 10 shot groups: no reading, 2814, 2815, 2813, 2805, 2819, 2815, 2813, 2815, 2806 avg: 2813 SD: 4.5 ES: 14...
