I picked up an H&R Buffalo Classic in 45-70 several years ago but have never loaded ammo for it. I have plenty of components and am ready to go....but have some concerns over my data and research for loads. Crescent butt plate and hot loads are not fun, so I have been looking for some mild loads to use deer hunting from a ground blind. Shots would be 100 yards or less, however I am not far from some long range (out to 1000 yards) shooting area so could do a lot of playing in an afternoon so trying to keep the load with 300 gr bullets about 1500fps...just fer fun. I would think I could hit my silhouette ram at 500 no problem when I nail down the right sight setting....
Here is data in my Lyman manual. Re7 33.0 1408.....Re7 38.0 1639 this is in Springfield with 32 1/2" barrel. Next page over. Re7 38.0 1428.....Re7 45.0 1811 this is in Winchester with 26" barrel. My gut is telling me that 6" difference in barrels will not equate to 211fps difference....am I incorrect?
Is anyone using Re7, IMR 3031, IMR4895, or Trailboss in moderate loads to 1500-1750fps? I have bullets 300, 350, and 405 already. Action is easily strong enough to handle anything I will load. My main concern is difference in data from the different manuals....I have looked in no less than 10 to get my range....but without a chrono, and books differing on velocity, I am riding the fence on starting loads......
Any info from experienced 45-70 shooters would be appreciated.
Thanks,
Steve
