how to find out the barrel twist rate

Most manufacturers list twists for their various guns on their websites, if you can't find it then...............

 

Get your brush, stick it on your cleaning rod, stick some masking tape round your rod and mark it...now start counting the turns over a known distance down the barrel, do it a few times to be sure.

 

With regard new barrels, it is an expensive excercise, commonly as cost effective to throw away the rifle and buy a new one!

just a quick question sorry if im stealing your post lol .. what if you was to use a more heavy bullet than 55 grn ?

 

In VERY simple terms you need a long twist to stabilize light bullets and a tight twist to stabilize heavy bullets, therefore matching the wrong twist to the wrong bullet weight gives instability, inconsistency and inaccuracy.

 

There is a lot more to it....

ok on there website it says its a 1.12 twist, what weight ammo can i shoot through this accuratly??

 

 

I have to say I wonder myself sometimes at twist rates and bullet weights, my .223 Tikka T3 Lite Stainless is 1-8 twist, yet it can deal with everything from 40-75g perfectly acceptably, and most brilliantly! :hmm::good:

Twist rate to bullet weight is only a recommendation, you'll never know what weight bullet your rifle will stabilize unless you try it, i know plenty of shooters who use bullets not meant to be suited for there twist rate but they stabilize them anyway.

 

only one way to find out for sure and thats try

I have a remington with a 1:12 twist, it doesn't like anything heavier than 55gr. even at 100 yds they are all over the place. anything 55gr or below is fine though it gets kinda choosy over long range, for instance at 100yds Remington UMC 55gr is spot on but at 600yds they are all over the place again, Winchester supreme are good from zero out to 600yds, but the only FMJ that are any good through it at 600yds is Buchsenpatronen 55gr . don't ask me why!!! Hope this is of some help
