I have the Encore in 375 H&H with synthetic stock. I have only shot
1 federal 270gr factory load threw it and it really kicked!! I ended up putting a limbsaver recoil pad on it which is worth it's weight in gold!! So put one on!! I have shot 200gr, 220, 235, 270, and 300 gr bullets at 50yds and it shoots everything really good! I have used Hornady, Speer, and Serria bullets with Winchester brass and Federal Match-Mag primers. Everything groups 1/2 to 1 inch at 50yds! I will try 100yds soon. I also went to the store and bought some ankle weights and put them in the Butt of the rifle for extra weight but I have not had time to shoot it since I put it in there. I put a leupold rifleman scope + standard TC scope base mount
with leupole rings and it is a nice set up. I also put the TC hammer extension on. The rifle kicks but I Luv it!! The 375 is an amazing round and will take everything that walks close and far away!! It can be a Brush gun or an open field gun!! I reduce the loads some when I shoot at the range but this rifle in 375 will never leave myside! I would recommend the 375 in an Encore and glad I bought one!! Put a recoil pad on and shoot! Good luck! Hope this helps!!
