I use H4895 in both of those calibers.You can get top end loads with the .35 and with the 45-70 you can get some pretty good loads,up in the 1800fps range,with the 405 rems,you just won't be able to wring out top velocity in the 45-70,if that's what you are looking for.H4895 has not let me down for either of these cartridges.Hope this helps.
