The 6.5CM does not have a good reputation in Ireland, at least not for dropping deer. Same as the 6.5x55 did not have the best reputation and there are two camps on this. All seem to agree that 308/30-06/270win do a very good job on deer. I am fascinated by the incredible BC values for such a small cartridge as the 6.5CM and it can be stoked up to good speed even with 20" barrel. I mainly used my 6.5 as a precise surgical tool and be a bit ahead of a 308 at distances over 400m. I started shooting 6.5 in 2021 and took close to 100 deer with her at distances from 10m to longest 630m. At first, coming from using a 308 for many years I was disappointed with the deer running. Of course some dropped on the spot but many didn't and ran further than what i was used to. After discussing with others I changed my shot placement more to the Hilar position which possibly helped a bit. For driven hunts I used a 308 and for very long shots I also had a 300wm and could keep comparing. Funny that you mentioned the 120gr Nos BT, years back when there were more 6.5x55 around that was the bullet of choice for many after other bullets disappointed. So much so that some guides would not take out a guest with that cartridge on evening Sika stag in the rut. Our deer are quite small but are very tough. Terrain is rough and can be boggy. When after females we try take the calf as well, maybe also the follower. Shooting in the evening one wants to avoid long tracking. Actually I sold my hunting 6.5CM today but we have 2 or three more in safe. My son has one as well. We mainly use 143 ELDX or 140 ELDM. I thought the ELDM was a bit more accurate. All going well I will be out this weekend for my first hunt of the season with my 308 CTR. Just getting all the bits together for two 7PRC builds one for myself and one for business partner which should be done in a few weeks as well as a 300WSM all have carbon barrels. The WSM to replace my 300wm that I recently sold.
