    284 win

    162 A-Maxs are known to be finicky- some guns love them and others hate them. Has become an irrelevancy with their production demise. As for the 180 Scenars, most guns will digest them happily but a guy I know (who was last year's F-TR champ at the Nationals here) has been having a nightmare trying to get them to shoot in his new .284 Walker F-classer. He's actually given up and gone to Hybrids to avoid more barrel life loss. In the other direction, I found that my .280AI hunting rifle really likes 150 LRABs which are notoriously variable in accuracy. Knowing when to cut your losses and accept your gun just doesn't like a particular projectile is something many loaders need to learn.

    A&D Scales and Adam McDonald Auto Trickler

    My std FX-120 scale has been rock solid from the point of view of not drifting during use. It's easy to see if anything has drifted as the scale will read ( from memory) -128.54 with the pan removed. If that figure changed, I'd then check / re-zero it.

    In ear hearing protection.

    The passive fit of any custom plugs is only as good as the impressions. Believe me, taking quality impressions is a lot harder than you'd imagine, and I've taken tens of thousands over the years. Ask any hearing aid manufacturer- they'd say probably one third of clinicians who do it all the time can deliver a top impression when it counts. As for the occasional operator with minimal training, good luck.. I only use custom plugs (various models made from high-end hearing aid components) and have mine remoulded about every 5-8 years. Ears vary in how they drift in shape over time. If you lose any weight at all, the fit of plugs can go to hell quickly. From what I've seen of mobile plug makers who do impressions at shows and events, the average standard is cr@p. Saw one impression at a show that had gone past the cotton dam and was hard against the drum. That's one small step from a disaster. They had NO idea what they were doing and the resultant fit would have been terrible.

    300 Norma Magnum

    That cartridge has become a favourite here for necking down to 7mm. Impressive long range wind performance with heavies

    It's more the damage to your wallet usually

    That is very useful info Andrew. Your mix-n-match approach has got rid of quite a few variables.

    I might have missed something but what distance was that Andrew?
  8. The 'change the gear for lower running cost" argument reminds me of folks who trade their bigger engine car for a smaller-engine car when petrol prices go up. The extra capital spend/ realising the depreciation on the old car would probably have paid for a decade of fuel difference.

    Best UK Varminting Calibre?

    Your std slow-twist .223 isn't that flash in wind, in fact the 53 V-Maxs in mine have exactly twice the wind drift as my 6x47L, and that's about the most slippery lower-weight projectile you can shoot through a slow-twist barrel. Just for giggles, I took my old VS Rem .223 out to the club on Saturday as it was only 300yds. While not strong, the wind was from three o'clock switching quite rapidly. You can see it holding good waterline (1/3 MOA) but I got caught on shot number 9 The next shoot, I changed tactic and waited for the dominant condition to come back. I was shooting fast off a bipod so the waterline isn't as tight as the more deliberate shots in the first shoot. Shame about the last loose shot- would have been a 60 otherwise..

    "5-8mm" @100yds with a rimfire is better than custom BR rigs I'd guess. I'd like to see a series of say four groups shot successively. Any pics?

    yeh, I'm wondering too..

    I'm afraid you're comparing apples with elephants there Bradders, The 85 limit applies to std continuous noise, not impulse noise. The mechanism of damage is different for each type of noise. The internationally accepted threshold for impulse noise is that no-one should be subjected to -peak- levels of 140 dB-SPL. You cannot do simple arithmetic on attenuated impulse noise then apply that figure to limits on continuous noise. I am a semi-retired clinical audiologist and have written articles on this very subject in case you're wondering why I'm commenting.

    Load testing??? I thought any intelligent buyer of a quality rimfire will try various ammo types to see what shoots best
