Hi everyone, I'm new to this forum and would like to have some support.

I live between Houston and Mexico and just bougth in Mexico a Weatherby Mark V .300 weatherby from a friend. The rifle is new and has a Range Certificate from Weatherby certificating 0.36" group. The certificatión is made with the computarized system Oehler, Im attaching the certificate. Does anyone know how accuarate is that system and the Weatherby certification? It seems to me to good to be true to have a factory rifle, with factory ammo and new barrel to shoot .36". May be I´m misunderstanding the certification or may be I'm very lucky to have such a good rifle out of the box. Does anyone know what is true?

I know the best thing to do is go to the range and shoot it, buuut I'm not able to do that until mid October.

Thank you very much for the help.

I have a 300 wby that shoots those groups with weatherby premium 180’s. Definitely would believe the certificate. Give about 4 minutes or more between shots for barrel life and be prepared for the recoil. I have a 6.5-300 and 257 that are the same. Just expensive to shoot unless you hand load.

I have and do, mostly for heavier bullets. No they don’t get much better, pretty much the same. I usually shoot everything at 200 when doing load work up to see the spread a little better. If you haven’t shot a lot of heavy recoil rifles you might want to research it to help get those groups. I’ve found sticking a stocking hat or similar between the gun and my shoulder helps tremendously when I’m doing load work otherwise I have a nasty bruise. I use a 2 piece rest and front rest about 3 fingers behind the strap button is where all my weatherby’s like to sit. I’ve also had better luck for long range data if I zero at 200 vs 100. Not sure why that is but don’t care. Congrats on your purchase.

Sounds right to me. I’ve had several mark Vs that shot 1/2 or sub MOA, and better with handloads. I’ve even had 140 VLD hunting factory ammo shoot exceptionally in a 6.5-300wby, and that “Depth sensitive” bullet is sitting about .225 off the lands!

Thanks again Nealm for your tips and knowledge. To be honest I got problems shooting with a .338 winchester and with the .300 win mag. I got down to 7mm rem mag an improved a lot. That was about 10 years ago and since then I have argued the BC of the 7mm over de .30s to avoid sounding like a chicken. But that was 10 years ago and may be I could get the mindset of the recoil and manage it. The rifle purchase was a “covid” opportunity and Im very excited with it!
Thanks again for all your advice!

For me every rifles different and I don’t expect tight groups till I’ve figured the rifle out. I’ll play with where it sits on the rest, rear bag and pressure against my shoulder. Sometimes I’ll hold down on the fore stock firm or lightly, sometimes not at all. If not at all, I have to focus on trigger squeeze more and consistent with how I let the rifle come back. To me, it seems they’re all different in some degree but that’s part of the fun except the nasty bruise sometimes

Great all around choice for hunting. I am a weatherby guy I own several. I have a mark V ultralight in 300 WTBY that definitely gets your attention when you pull the trigger. I dont shoot the heavies in it to much mostly 150gr bullets and they demolish deer. If i am going to shoot heavy i use my 340 WTBY. Congrats and good luck on the new purchase...

ALL of my Rifles are “Zeroed” at 200 as well 👍🏻

I have a few MK V in 300 WBY and one in 338 LM. A 60 year old made in W. Germany, a 40 year old made in Japan, the rest made in the USA. All shoot 0.5" with hand loads, none of them are RC (Range Certified). I load 180 grns in 2 and 200 grns in the other. IMR4350, IMR7828 and RL22 work great. My son and I took a pair to Africa. No muzzle break on the German. Recoil? If I keep it under 50 rounds I don't feel it, except for the 338.

The one in my profile pick is a Winchester chambered for the .300 Weatherby. ($279.00 34 years ago) still driving .24" groups at 100 yrds. Over the years I added a thumbhole Boyds stock and a muzzle break.
168 Grn. Barnes TTXS on top of 84.0 grains of IMR 7828, just over 3300 fps.
