.223 ammo bullet weights

Snellstrom

I'm looking for a little technical info here.
I've got a mini-14 and I know we've all covered the accuracy issue with these and I've done all the "mods" I want to do so my next step is that I'm wanting to try some heavier bullets and see if I get a little more help out of that. I haven't found any info on what the twist on Mini's is, mine is about a 5 or 6 year old Ranch rifle, do any of you know the twist on this rifle?. How heavy a bullet can I step up to and still expect stabilized bullets?
I see Black Hills has some 68 grain stuff and didn't know if it will fly with my rifle.
Please no more tips on accurizing this gun I'm through with that part of the program, now I just want to find something that it shoots a little better than what it's doing with the 50 and 55 grain ammo.
Thanks

Mine was 1 in 12. It was pretty much limited to 60 and under.

if it is 1/12 try 40 or 45 gr,had good luck with a T/C barrel with that twist. if you want to measure twist,make a line straight up your cleaning rod, stara new bore brush in the barrel,make aline around the rod,start with first line on top when the line comes around to the top again make another line around the rod an measure between the two lines.

gun control is not about guns, it is about CONTROL!

Snellstrom,

I would stick with the 55-60 gr. range for that rifle. Best velocity/accuracy combo. By accuracy in this case I mean droppoff. What you gain in BC you lose twice in loss of velocity. Long range shots with heavy stuff in a Ruger won't work really well. With a good accurized Ruger shooting 55's near max will get you consistently out to 500 yds. You will need to start allowing for a reasonable amount of drop @ 300 yds.

We have the second amendment so that all the rest are secure....UNK>

I liked a 40gr Speer TNT in mine, for groundhogs and prairie dogs.
There is a simple trick to determine the twist. Respond if you want me to post that trick.
