Twist rate v bullet weight

[woollyback 0]

Im off to my local Firearms Dealer soon to stock up on .223 rounds; I have a howa stainless with a 1:12 twist and it shoots 55gr prem accutips at foxes for fun but I'm gonna be going for roe in scotland and possibly munty later this year so I was wanting a heavier bullet for this. My FD has some 64gr and 75gr in stock, but will I get acceptable groups with a 1:12 twist? Obviously I'm to buy both and test myself but if someone knows for example the 75's are too heavy for my rifle it'll save me a little money. Cheers, woolly

i wouldnt bother with the heavier bullets if your getting good groupings with the 55gn why bother

 

if you hit them in the right place it will be just as dead wether 55 or 75gn

I've only ever shot roe in england and with a .243, but if a 55gr from my .223 with be adequate for roe in scotland then Im laughing, thanks

The 1:12 twist of your barrel is probably to slow to stabilise a 75gr head,it would probably need a 1;10 or a 1;9 twist,

however I reckon that you would probably be okay shooting 64gr heads,hope this helps.

 

 

best of luck,

Thats what I'd thought, the 75 being too heavy. I know its all about shot placement, but would the heavier bullet not have an advantage or would the 55gr take roe down easily. does anyone on here have experience shooting Roe (Scottish obviously) and/or muntjac with .223's?

The 75gr head would definitely have an advantage being heavier,I have never shot roe with a .223,I use a 22-250 for them in the past I have used a 55gr head,and if the shot is placed in the engine room or any other vital organ they will definitely go down.

1:12 twist Howa = 55gr maximum

 

I know, I had one and that's what it shot. 62gr FMJ wasn't on the paper at 200y Bisley target.

 

Regarding a deer bullet, a 55gr is more than enough for a roe BUT you need the right bullet. You want a softpoint really as it has more penetration, but still reasonable expansion on a deer-sized animal. If you put a 55gr SP in the heart/lung area from < 200y (ideally < 150y) then Mr Roe will fall over like a stone.
