300 rum

[J-L]

I had the same chrono in your picture, actually still have, however usability of the garmin blows it away, and the best the feature is how tiny it is. Highly recommend it.

When I had the factory 26 in. barrel on my Rem 700, 300 RUM I was getting 3360 fps with Barnes 180 TSX , TTSX and Berger HVLD's. 3630 with 150's but never hunted with them. I put a Bartlien 28 in. 5R Varmint contour barrel on it. Action trued, bigger recoil lug, different firing pin spring. Replaced the Timney trigger with a TriggerTech and got it cerakoted 3 years ago . I have never hunted with it yet because it weighs so much now ! It used to be my go to rifle. I should of put a carbon fiber barrel on it. With factory barrel and Retumbo/Barnes 180 TTSX I could shoot 4 shot half inch groups all day. On a bad day 3/4 in.. With new barrel with N570/Berger 215 it's bug holes at 3215 fps ave. Not at pressure.
Same with 180 Hammer Hunter and H1000 3432 ave. fps.
300 Win Mag 180 Hammer w/RL26 3303 Ave.

...one helluva lot of power there....game must really be working out !!

I'm not too sure about those hammer bullets Just my opinion but don't seem like they would perform

Read up on them, they seem to have a track record of complete passthrough's which I prefer over the Accubond(personal experience). I wish they all fell where they were shot, even hitting them in the vitals. I want a blood trail.

It's a rem 700 26in I was thinking I could get 3300fps with 180Accubonds using RL26 or RL25 , hey Aussie hunter Steve is sounds like your rifle is a straight up winner 0.5 at 1200 absolutely nothing to complain about there that's for sure

You'd likely get 3400 with one of those two powders. I knew a guy that was getting 3400 with 96 of RL25.

Hammers don't have pass thoughs unless close range from what I've experienced in 4 different calibers . Even if do they've shed their pedals and have done damage. I've used a lot of different bullets in a lot of different calibers in the last 47 years. Most work. Some better than others. I've found it's the velocity and distance of what the bullet I capable of. I have some favorites but I use them at I know will work. I won't get into them.

I ran 97grs Retumbo with 180AB's and Sciroccos a long time ago at 26".
Good friend of mine used 98grs.
Performance on deer and pigs was thoroughly impressive.
No brakes back then. Younger and a lot tougher.

I used 99.0 - 100.0 grs Retumbo. Right at pressure.
Later I had a magna brake installed. I shot a lot more accurately with 40% reduced recoil. Made me a believer in brakes since 1996.

 

[Phil Rizzo]

You certainly found pressure I'd think.
What a wicked machine it HAD to be.

Seems I was around 3250 if I remember. Been 20+yrs

Don't over look the 200gr AB over 91-94gr of retumbo I don't have pressure issues at 93.5 in my gun, the COAL is 3.750 1/2 moa-3100 fps. Work it up slow, you will be happy you did.

Wonder what N570 would have given for velo?

I did the same with my first 300 rum. It was a factory Remington with a 26" barrel. I was shooting 100 grains of retumbo with 180 swift sciroccos at 3400 fps. I shot it about two years without a brake then I decided I wasn't man enough and had a gentry Brake installed and I was much more consistent with it.
