I prairie dog hunted for years. The 6mm’s were my long distance dog guns.

Ive got a 6mm Remington. Factory 1-9” twist. Ive shot 87gr vmax and 105gr amax out of it. The 87’s shot flatter out to around 500yds. The 105’s were better past that.

My 6-284 is an 8” twist, that I’ve only ever shot 105gr amax and 105gr Berger vld’s out of. This rifle is exquisite at long range. I only ever brought it out if the shots were over 700yds.

240 weatherby 10” twist. This was my most expensive build and least favorite. I took a gunsmiths advice on caliber and twist and wouldn’t do either again, for this type of rifle. Don’t get me wrong. I killed many many prairie dogs with it, but found even the 6mm rem did better past 500 with its heavier bullets. This barrel with the 10” twist shot 70gr and 80gr nosler ballistic tips incredible, and I could reach way out there with them but I made more hits at long range with the heavier bullets.

I have a 243ackley with a 9” twist that I never really did much with. Ive got a good load with Hornady 75gr hp’s and H414, but never hunted with it. Whenever I dust my old dog guns off again, I will probably work up a load for the 105gr amax.

My 240 weatherby barrel is shot out and the 6-284 doesn’t have a whole lot of life left in it. Whenever I get around to rebarreling it will be with fast twist for heavy bullets.
