Anybody convert a M70 CRF LA BDL to….

Unless you are going smaller or larger in case diameter, I don't think you will have an issue.

That is why I asked the question….

6.5x55, 6.5 rpm, 6.5x284 all represent larger diameters and a change in length.

6.5 Sherman is the easy button, but I told myself I wanted a cartridge with factory ammo.

My goal is basically to launch a good hunting mono of 120-150 gr with a g7 bc over 0.25 to 3000-3200 fps with a 22" barrel. With easy to buy dies, brass and ammo. So…..seems like I have to give up something….hmm.

I converted a pre 64 into a 6.5 284 with no feeding issues. If you are doing a mod 70 crf just put 2 round in the mag and start to cycle the bolt you will know if the bolt is going to pick the up and feed.

6.5x55 slightly larger head size should feed with little issue.
6.5 284 same head size, larger body, shorter length, probably need some adjustment
6.5 RPM same head size, larger body, length designed to work in 30/06 length actions may need the same feed lip adjustments as the 6.5 284 but would give you lots of case capacity to play with. Brass may be an issue.

Sounds like you really want a 280 A1. 3050fps with a 150gn through a 22" barrel is usual.
