How heavy could I go? (243)

[laker415]

I am thinking about picking up a rifle in 243 on my next days off. I am curious how heavy of a projectile I can push out of a 1:9.25 barrel. I am interested in weights in the 90-107 grain but am unsure if this barrel can do it. Any opinions are appreciated. Thanks.

1:9 is a great twist rate...... Should definitely push out what you want..... No worries imop

As an aside, the Ruger precision rifle, which is designed to group heavy bullets at long ranges, has a 1:8 twist rate....... I wager you will be more than fine at 1:9..... Most hunting rifles I have seen in .243 have a 1:12......

For best results I wouldn't go over 100 grains with the 1 in 9 twist.

My Parker Hale with the 1 in 10 twist shot 100 grains for deer hunting just fine but seemed more accurate with 80 grains.

I've had (3) 243 rifles all with 1:9 twist. They all shot 75-100 grain loads with Superb accuracy, with 95-100gr being the best.

I'd try the 95 ballistic silver tip. Good range and good hitting power. Or a 100 grainer in a PSP. You can try other bullet types nd weight but the above two are great for deer.

105 and 107 will very unlikely work for you. Stranger things have happened though.

I've got a 6mm A.I. With 1 in 9 twist. 105 bergers I couldn't hit the target to even see how large the group was. With 100 grain cheap hornadys it would group a little over an inch.

Thanks for the responses. I will keep this in mind when deciding on my purchase. I am sure I could get good performance out of a 90-100 grain projectile. This rifle will be a target rifle with the possibility of a deer rifle in the future.

Don't sell the 243 short.

An 80 grain bullet is more than enough for deer at reasonable ranges and paper sure don't care what you kill it with.

If you feel the need for heavier bullets you could move up to the 7.08, just the "in between" the 243 and 308 - a little more recoil than the 243 with a wider (weight) range of bullets.

I always thought the .260 Remington would be a superb cartridge.

If I didn't already own a couple 6.5x55's I would probably have bought one by now.

A .257 Roberts looks pretty good too.

I just want to play with this cartridge. Once I shoot out the barrel then I will look into a 260 or 6.5 or maybe just a faster 243.

The 243win using a 9.25 twist barrel will shoot bullets up to 100gr. However the 105 VLD berger and 107 Sierra call for a 1 in 8 twist, they will not stabilize in the 9.25 twist.
