My 300WinMag

Post by arkhangel5 » Sun May 17, 2015 1:31 pm

I have this Savage 110fp in 300WM that I have been testing heavy bullets in.
The crappy plastic stock was the first thing I changed on it, had it in a Bell&Carlson Durastock with pillar bedding.

I won a $250 off Manners stock gift certificate from a match and used it to get a Manners T2 adjustable, with CDI DBM setup. I bought from in stock, rather than waiting 3-4 months for a custom stock.

I have been testing Berger 215gr Hybrids in it. I had my sights set on getting 2850fps as my target velocity, and I began testing different powders to see if it was possible with a 24in barrel. I tried H1000, and then H4831SC, with both these powders at book max charges, velocity was topping out at 2750-2800fps, I was not happy.

Then a friend suggested I try Retumbo, which I thought would be too slow for a 24in barrel, but what the hell, I wasn't getting the velocity I wanted, what's to lose. I am now a convert to Retumbo.

In the following video, taken in Slo Mo with an Iphone6, you will see me smiling, as Retumbo gave me what I was looking for and more. Not only do I get the speed and accuracy I was looking for, I got it without going beyond book max, and it will feed from my magazine. With this combo I am getting 2930fps with ~1/2MOA accuracy and a low SD.

The recoil is stiff, and you will notice the shockwave running down to my leg, but I got what I was looking for. Vid was shot at PMRPC under the 600yd cover. Rifle is still a work in progress, as I am having some issues with the DBM setup.

Rifle Specs:
Savage 110FP 300 WM 24in barrel
Manners T2A stock with heavy fill
Nikon Buckmaster 6-18x40 md scope
EGW 20 rail
Harris Bipod

The bayonet looking thing on the end of the barrel is a Magnetospeed Choronograph.

What do you think?

Hey S,
What do I think? I think target 20 is a fine place for you to be during a match. Freakin' Mexican. [smilie=011.gif]

Haha, it's a 300wm guys, not a .22lr. Recoil is what it is, either accept it or move on to something else. That being said, what you cannot see in the vid is the 1 inch recoil pad on the Manners T2A. As hard as it recoils, its not bad. Not something I would compete with but still not bad.

I have shot a 338 Lapua Mag unbraked, and can tolerate that level of recoil for a few shots, again not something I am going to shoot all day, but tolerable.

A muzzle brake is in the future for the 300WM but for the time being it is manageable. :ber

Btt,
A muzzle brake is in the future, but I still wanted the data, so I could have something to measure the brake performance against. I am a big believer in recoil management and am still looking at the different designs to see which one I want.

arkhangel5 nice rig, I wondered what my rifle would look like in a Manners stock instead of the XLR chassis. I had the same issue with the powder I tried 4831, h1000, RL22, and none gave me decent velocities with the 208 Amax. I don't have any local shops with retumbo so I tried IMR7828 and bingo I was finally getting over 2900 fps. As far as brakes are concerned I'm using a Vandenberg Custom brake, it tames the recoil pretty well feels like shooting a unbraked .223.
here's a pic of the brake on my 110fp

here's video of the brake in action (my brother is on the rifle)

Hold on a second there Steve - in your photos in your house, I think you have the same old framed picture on the floor, in a frame. Didn't you show us that 10 years ago ???

And nice shootin' - must be nice to have such a nice range close by. Up here the club has 100 yards only - I can do that in my front yard!

And one more thought: for those super-full cases -- try setting them on a cheap vibrating aquarium pump for a few seconds. The whole loading block even. Packs that powder down like no one's business.
