    Hornday A-Tip vs Berger Hybrid

    I have shot the 153 Atips and 153.5 LRHT in my 6.5 PRC, 7 twist. I got slightly better accuracy with the Atips, and a bit more sped, but after my barrel was a little worn the Atips started blowing up; for example, I lost 5 shots in a 50 shot long range match where I was shooting great but 5...

    Help with POI drift on .22 PCP rifles. Temperature or something else?

    I can't speak to the guns you guys are using, but I have seen the same thing to a lesser degree. Air guns in general just aren't built as solid/stiff as firearms. You can go through the usual exercise of checking to make sure the barrel is fully floated, that there is nothing making contact...

    Bartlein BB steel barrel, wearing one out...

    With my last 2 (regular) barrels in 6 Creed, the barrels would speed up for the first ~200 rounds, like Punkur67, then slow down around 1000-1100 rounds. They would then continue to shoot well for another 500-600 rounds or so, and then either slow down more or start to throw fliers. So...

    Loading 6.5 PRC to CM speeds

    O.k., that looks more like what I would have expected. Back to the OP‘s question, looks like 4831sc or H1000 might work (depending on brass capacity), and for the shorter barrel I would probably try the 4831sc first. Not sure about the VV powders, I don’t have much experience with them.

    Loading 6.5 PRC to CM speeds

    Understood. It might have something to do with the brass; I’m using ADG brass with a H2O volume of 68.3, other brass might have less volume. But when I first started out with the 6.5 PRC, I tried Retumbo in some loads and got less velocity than with H1000, so that was part of why it seemed...

    Loading 6.5 PRC to CM speeds

    Interesting. Seems odd to me, since Retumbo is slower. And I think there might be something wrong with the fill % number, I don’t think 54-55 grains is a compressed load. But I do see Holden has 55gn of H1000 listed as a max load for a 153gn ATip bullet, so I guess my load might be hotter...

    Loading 6.5 PRC to CM speeds

    It seems doable to me. I shoot the 153.5s in a 28” barrel with a moderate load of H1000 at just about 3000fps. I think once you adjust for barrel length and maybe drop the load a grain or 2, you will be right in the ball park. I don’t see H1000 on the list above, but it should be in between...

    Please help with seating issues

    You would have to check your lot of bullets to be sure, but most of the time the BTO variance is less than the OAL variance. So seating depth wioll be more consistent, even if OAL varies more. Unless the OAL variance is creating problems due to mag length, I would focus on BTO and not worry...

    Resurrecting Cutting Edge Bullets 32Grn

    Sorry, no progress, but I can give a little more info on what I have done with the 50gn bullets.. I tried Longshot, AA-9, HS-6 and VVN350. I ended up with a reasonable good load for the rounds with 2.75gn of HS-6, giving me ~1170fps. 2.3gn of VV N350 was similar and maybe slightly slower @...

    Good Price On Norma .22 LR

    CCI also makes non-lead 22 that shoots poorly. And the lead ban is only for hunting, if you just want to plink or shoot targets, you can use traditional ammo. You can also load your own lead free 22 using Cutting Edge’s products. Cutting Edge has told me that it qualifies for CA’s lead free...

    Is clean brass more accurate then dirty brass?

    Thanks. I have only tried graphite and HBN, and have not done any calibrated testing, but I would say my results between HBN and graphite support your: Graphite seems pretty consistent, and HBN was all over the place. I wasn’t even aware that there was a dry powder version of moly, I might...

    What did you find to be the best lubes for consistency?

    Seating Depth Analysis--My Assessment Meter is Pegged Out.

    Ah, sorry, I was thinking about it backwards. Have you tried longer jumps? I had a rifle that shot best with a .120 jump. Not sure how deep that puts the bullet; the 185g bullet is probably pretty long for the .308 case (I’m guessing, sold my last 308 in favor of a 6.5 a while back)...

    Seating Depth Analysis--My Assessment Meter is Pegged Out.

    If the end state for the rifle is PRS and the mag length limit is .020, why aren’t you focusing on optimizing .020 and less?

    Launching - MDT Training Shot Timer

    Hmm . . . When I try to set the time higher than 60 seconds, it resets either to 0 or 60. Not sure what I am doing wrong.

    Launching - MDT Training Shot Timer

    Is there a way to do PRS style timing, with par times of 90-120 seconds with this? I just got one and haven't worked through everything, but I can't figure out how to do a par time longer than 60 seconds.

    109 ELD M ?

    .284 to .286 sounds right to me, definitely in the ballpark. I've been using .290 with a 1:7.25 barrel, but I switch to ATips after 600yds so I have not spent any time refining it.

    Do the pros use stainless steel pin/wet tumble or Dry Tumble?

    Do what works for you, and allows you to get the best consistency. If you are wet tumbling and getting peened necks, sticky necks, or shooting pins through your rifle YOU ARE DOING IT WRONG. But if doing it right is too much thought, time or trouble for you, don't do it.

    109 ELD M ?

    I like them. The are a lower cost alternative to the 110 ATip for distances out to 600. After that, the Atip shows better BC. When they were first announced, the chatter was that they would be the same profile as the ATips, but that turned out not to be true. But they do shoot very close to...
