Looking for .257 Roberts loads using 110 gr Hornaday interbond bullet. I have IMR 4198, 4350, 4831, 4895, Varget, and CFE223 powders on hand. Thanks in advance.

Welcome. I've used both H4350 and IMR 4350. My default load for 110-120 is 42.5 of H4350. Seems to work well with all bullets. I've also used the same charge with IMR 4350. This gets me about 2750 fps from 115 grain Ballistic tips. I've used it with 110 Accubonds but never with a crony.

Either 4350 is a really good burn rate for the Roberts.

I've not played with the 110's but I shoot 41.5 grains of IMR 4350 and a 117 Sierra for 2815 fps and is extremely accurate.
If I were to play with the 110's I'd start right there abouts (41 grains) in MY rifle and go up from there.

I have never had any luck with the 110 acubond.
I would love the hear more about it.
I have had great lock with H 414...tj3006

Try this again tonight and see if I can get it posted.
