The 6.5 CM is the way to go. 260 is on the way out with relatively little ammunition being manufactured for it and few rifle choices. 6.5 CM was tough to find at times during the Covid panic, but more of it is being loaded than just about any rifle caliber other than .223/5.56 or 7.62x51. It will give you significantly more loaded options than 260. Development on the manufacturer side is also finished for 260. It's a good round, but the 6.5 CM handles longer, higher BC bullets better and it's clearly where manufacturers are focusing their R&D, engineering etc efforts/dollars due to market demand. Both rounds are reloader friendly, but you'll find more data and support for the 6.5 CM. The market spoke and chose 6.5 CM. While it's fashionable to mock the 6.5 CM due to the marketing hype surrounding it (legitimate criticism for sure), the bottomline is that it's a wonderfully effective, low recoil, accurate, hunting and target round with a huge number of rifle and ammunition choices available. It's a winner within reasonable limits, though there's nothing magical about it.I own a 300wsm and 30.06. I am considering purchasing another rifle for mainly my children to use as the grow up. Think a 6.5 CM or 260 Rem would be a good option. Which one is better and why? I am a reloader.
In what possible way is this true?260rem is a better option .
That 7mm 175gr Partition is a real killer within reasonable ranges. Love that in my 7x57Since you reload, I'd go with 6.5x55 and 155 gr Lapua Mega or 156 gr Norma Oryx. I have a Tikka T3X in 6.5x55, and it's a tack-driving, pleasant-shooting, lightweight rifle. As much as I like both of those bullets, they're both pretty low BC, so range is limited. Since Woodleigh is rebuilding, their 160 PPSNs will be available at some point, and BC on those is about .51. At 2500 fps MV, that'll get you out to about 300 yards and still right around 2k fps
I'd also consider 7mm-08. You could load up to 175 gr bullets for it, and performance would be similar to 7x57. It has a lot more reach, albeit with a bit of an arc, than most people realize. A 175 gr partition fired at 2500 fps still has right at 2000 fps of velocity and about 1500 ft-lbs of energy out to about 350 yards.
I'm getting right at 2400 fps with Woodleigh 160 gr in my Swede. Recoil is very mild, accuracy is stellar.Sample of one and all that, but my Tikka 6.5 CM shoots the heavies (155 gr Lapua Mega reloads) very well. RL-17 gets me 2,637 fps at 66*F. All 6.5 CMs may not have the longish throat as my T3X, however.
But - the 155 Mega load pushes the recoil up as well so that may not be the best option for a kid's rifle. I bet it would be awesome in the bush, however.
