He is 13 now, and we haven't got anything booked yet, guessing we won't make it until 2025, so we have some time. I am expecting him to grow, physically and in confidence by then. He already has a longer reach and bigger feet than me, just like a 100lbs lighter. I don't have any bolt rifles that are appropriate for him yet, so he usually sticks with 22lr and his 6.5 at the range. A suppressor is definitely on the agenda as is a lighter rifle for me. I was thinking about selling my 300 RUM and picking up something between a 7mm-08 and 280 AI. Whatever caliber I settle on it will be threaded for suppressor.
If he will be 15 or so by the time you hunt there shouldn’t be a problem getting him up to a bigger rifle. I would get him shooting as much as possible. Shotgun sports are a great way to get really comfortable handling a firearm a getting super comfortable with recoil.
I’ve been shooting a .375 since I was 12. Sounds like I may have had a similar build as your son. I was over 6’, but built like a sickly giraffe. I was however really into shotgun shooting. It was nothing for me to shoot 300 to 500 rounds per week. This helped more than anything to keep me from being recoil shy and to develop great form In handling a long gun in a way to minimize recoil.
I have a rifle suggestion for you. I have been super impressed with the Bergara Premier Highlander. It has a great stock, Custom quality action, trigger tech trigger, and a quality suppressor ready barrel. They have discontinued this model. I have seen them for sale recently in the 1,300.00 range. It cannot be beat for that price. I bought a couple in 6.5 prc and gave one to my sister who is also remarkably recoil sensitive. It’s shooting cloverleaf groups with factory ammo. She bought a suppressor for it and put it to good use on a big Kansas buck this week. They offered the highlander in a number of calibers that would work for your application.
Whatever you do, get that safari booked. I hope your daughter comes too. There is no better investment you can make in your children. My dad took me to Africa for the first time when I was 12 and it changed my life forever.
About 12 years ago my dad had a massive stroke when he was 56. He has needed 24/7 care since then, and I am his primary caretaker. It looks like I may end up spending more years taking care of him than he did raising me. His speech and language is very limited since his stroke. Every now and then when I’m sitting with him he will squeeze my hand and say “Boy, we did some things.” I know exactly what he’s talking about. I reply “We sure did Dad, we sure did….”
Here is photographic proof of skinny 12 year old sureshot375 with my dad and a kudu I took with a .375.
