Re: Very Low Recoil Deer Rifle
I understand your commitment to keeping your grandpaw out in the woods.
I see that you posted ranges out to 400yds, would he be shooting this distant or keeping his shots in closer?
One other thing, if you handload, have you considered reducing the loads?
I have a Ruger Compact in .308 which is only about 6 and a half pound field ready. I dropped some handloads which use a 125gr Nosler BT @ 2350fps. My 5yr old grandson has no problem shooting up to around 10 rounds at a time through it. (After that he gets a little stir crazy.) The loads are found on the Hodgdon website under Youth loads.
Just another option to building him a lighter weight rifle, shortened stock and lighter loads. Handloading some bottom end stuff you can still get away with using a little heavier load, but not using top end stuff. Remington and Federal both load reduced recoil loads for the .308 which are good for deer out to 150yds or so. One is a 125gr bullst the other is a 170 gr. At the loaded velocities, they both have decent penetration for use on whitetails.
Just throwing out other options.
On the .243 the 95gr bullets do well in a 1-10. I have used them for years in a couple of .243's. I have loaded them to the max and down to the minimum loads and had good luck with both ends. With the BT's I found that anything leaving the muzzle at around 2800fps worked great out to 200yds, from just about any angle. The higher the velocity the more critical the placment do to hitting heavier bone. When they hit at the higher velocity they tend to have more of a splatter effect and not penetrate as much.
SImilar to mentioned above, if you handload or have a friend who does, you can talor the loads to a standard rifle which will have little recoil, especially if the stock fits him and you add the recoil pad. I have loaded for several small framed kids who shot the 243 including my daughter when she first started hunting. One of them was totally recoil shy as well as didn't like the muzzle blast. I used some AA-3100 and the 95gr BT's and it worked out great for him.
Good luck in your decisions and hope you get to spend the time your looking for in the field with your grandpaw.
