Hi Guys,
Single shots are good. Allows seating the bullets out a bit without worrying about Magazine fit,
but a bit of a pain loading singly in my Savage M40, although worth it when you check the results !

.
I don't know what all the fuss is about with twist rates, and bullet weights, though.
The Hornet was designed in the days of 1:16 rimfire twist barrels and 45 grain projectiles.
If you want to shoot heavier bullets, then the .222 or .223 come to mind.
Why you would want to in a Hornet escapes me,
as the modern lighter bullets and Lil'Gun powder are dynamite.
The Savage M40 single shot is 1:14 twist. It will handle the 50gr's OK, but I don't have a need to.
It likes the 40gr Nosler BT's best together with the Hornady factory 35gr V-max.
and,
I also have an Anschutz 1730 5 shot mag fed, 1:16 twist,
which also likes the Noslers in 40gr.
I've tried loading my own 35gr V-Max'x but can't seem to get the same accuracy as the factory.
I Lee crimp all my loads, and use small pistol primers.
Had the two out this last weekend and shot a few groups.
The Savage is easier to shoot weight and stock wise, with it's sleeved heavy barrel and flatter fore-end,
but suffers a bit with the 2.5lb trigger pull weight.
I don't use the Anschutz mag with the Noslers. They are seated out too long, so I just single load over the mag OK.
Hornady 35gr V-Max will fit OK, as do all other factory rounds.
Trigger pull weight is down to 12/14ozs. 20x power Mueller scope fitted.

Got to shoot the Noslers at 200mtrs with the Savage some time ago. 16x power Tasco scope fitted.
They handle the distance fine, although I suspect that there would be a bit more deviation with a stronger wind,
but a bit tighter with a lighter trigger, and a bit more power on the scope for my tired old eyes.
I could lighten the pull with a replacement rear spring, but I haven't bothered as it's shooting good enough for me.
Makes me have to concentrate a bit more on my trigger control !

cheers,
SS
