I have owned over the years various, .22Hornet, .222, .223 and .220 Swift, and seen many others performing as well.
A .22PPC would be nice to shoot, IMO, as would a Fireball.
A .22/250 probably a bit more practical than the Swift.
I still shoot the Hornet and the .222. Pretty much close to each other, at around 3,000fps with the 40gr pill, but both a pleasure and fun to shoot and reload for.
I found the Swift a bit over-kill, over-powder, and over meat damage.
Wasn't over impressed with the .223 compared to my other 2, so passed it on to my son.
Surprised me how accurate the little Hornet could be,esp my Savage Model 40, even though it's a bit of a pain single loading into the cone breech.
From advice gleaned from various sources on the Net, I have switched to Lil'Gun powder, and Small Pistol primers,
(and use a lee factory crimp die, when I've a mind to.)
Still not sure whether the crimp makes that much difference in all situations, bullet and brass wise. Maybe some !
Just been out, shot the .22's and tested some Hornet crimp, in what I deduce to be the best brass available, RWS.
A bit inconclusive, certainly with the 40gr Nosler BT's, but maybe a bit better with the Sako 45gr FMJ, which have a crimp groove.
I think the difference would manifest itself a bit more with thinner, inconsistent necks,
as the problem is consistent neck seating tension with the thin Hornet brass.
(The RWS has thicker, more consistent brass !, but then again, holds a little less powder than say the RP)
I acquired a box of old Sako 45gr FMJ projectiles for a bit of fun shoot. Unusual little bullet, probably to minimise meat and pelt damage on any varmint Russians !
They've a smooth crimping groove.
Interested to see how they would go compared to my favourite 40gr Nosler BT's.
Not as good. The crimped group showed a bit more promise, but with one wide !
Could have been me, as I'm no benchrester, and neither are my sporting rifles.
Some pics; show not much between crimped and not in Hornet, or my .22H and .222 grouping with the 40gr Ballistic tips, at 100yds.
