55gr V-Max load w/ IMR 4895

Loading Rem 700 SPS .223 and Ruger Mark II .220 Swift. Any load recommendations with this duo?

Welcome to the forum.

4895 is really too slow for that bullet weight in the .223. You'll like it much better with 69 grain bullets and heavier. It won't burn efficiently or consistently with the light bullet, which adversely impacts accuracy, and may cause secondary pressure spikes. I recommend you switch to 4198 or Reloader 10X for the .223.

4895 may do OK in the bigger 220 Swift case? I don't have any personal experience with that, but overbore chamber dimensions offer additional resistance for the powder to build pressure against, since the bore is a smaller portion of the total chamber area. So it may do fine there? I'll leave it for someone who owns a .220 Swift to comment on that for you.

i always use IMR 4198 on light .223. have you looked at the Hornady manual to see if they have a proven load with 4895? falling into line with what unclenick said, I use 4895 to load 68gr. BTHP, but not the lighter bullets.

4895s

Most of the reloading manuals list one or more of the 4895 family with lighter bullets, and I use it frequently for them also, with superb accuracy. But its hard to get enough behind a light bullet, because it is slow for the weight.,and loading for the heavier bullets does go forward more easily, since the bullet weigth and powder volume are a better match.

Thank You

Thank you for the re-direction. I believe that I will go with 4198 for the 55gr and save the 4895 for heavier loads as ya'll suggested.

Sincerely,

Scott Casey
