DiscoveryOPT 3-15x50 Field Review | 8-57mm- 8mm Mauser Test Rifle. 

Morning Dave!! Not much out on 8x57. Its a favorite of mine!! I have one in a Arch Angle stock I have worked on a little. It shoots well. I have wanted ta work up good load for ling time. 4064 and a Sierra 175 has been my load for decades and it still is OK. Kills well @ 2650 fos.

Mausers are top notch and well underrated

Absolutely love the horseshoes and spurs scope display holder 🔥

I have had many custom Mauser rifles made on Large Ring 98 actions that started out as 8mm. Most of them have been the VZ 24 intermediate length action a few Turks were thrown in and I have a DWM 7mm that has its original barrel. A good friend of mine had several 8mm he hunted with he even had one rechambered to 8mm-06 it was a real thumper. Those steps in the barrel actually made it stiffer. Years ago there was a gunsmith in the town I lived in that would buy Mauser rifles and take the barrels out and put them in his lathe and machine a taper on them removing the steps. It was time consuming and he learned they would sometimes warp making the barrel useless. It made the rifles look better but not always shoot better. My 7mm Mauser has the original barrel I just cut it back at the first step and recrowned it. Didn't seem to hurt the accuracy it still shoots handloads well enough to hunt. My friend would buy surplus 8mm rounds and pull the metal jacket bullets dump the powder in a pan and replace the bullets with the same weight hunting style and use the same powder charge and primer. He just resized them with a die without a decapper pin installed. If the primers were corrosive he made sure to clean the barrel after shooting some surplus 8mm was non corrosive but Berdan primed he even found Berdan primers and reloaded them. Commercial 8 Mauser ammo was hard to find back then. Thanks for the video.

Dave. Thanks, another good video and shooting. If you reload it will be interesting to see the improvement over the factory ammo. Thanks for sharing and take care.

Good morning Dave , Yes most definitely reload and develop a hunting load. I use Nosler 8mm bullets in my CZECH 98/22. I harvested a mature Whitetail doe with it. I really dig your Scope holder Showing your Cowboy side.

I have been liking these 3-12 & 3-15 & 3-18 scopes for hunting. Just a lil better then 3-9.

As my hunting mate would say Dave" That's minute of pig, lets go get 'em." But I'm sure you can find a sweet spot reload for that Mauser. Great vid as usual Dave, looking forward to the next one, mate.

Still, Good shooing by you. Beautiful wood on the stock!

That looks like my old Remington VLS stock for my 243 I sold off decades ago!

Congratulations on getting a scope to review. That is so awesome 👌 I need to step up my game plan. 😂 On those scopes I want to know if it is FFP or SFP also if it has a capped windage turret. Or if it is exposed. And the number 1 thing with a exposed turret does it have a zero stop. If it does how easy is it to set. If you remount the scope to a lighter recoiling rifle. try a tract test with it and shoot a square . Like zero the 1 mil up 1 mil right one mil down to zero 1 mil left. Back to initial zero. Love your videos keep them coming

Dave, I think you can develop a sub moa load easily for this beautiful rifle.

I would suspect the barrel given it's vintage. However it can't be too bad given the groups. I agree it's the Core-loct ammo. You'll have to invest some significant time and effort in developing a load to see what the possibilities are. Is that worth it is the question. Does somebody love this rifle enough to justify that investment? I would guess the process would be entertaining/informational enough for us in your viewership to warrant the effort.

Rifle and ammo combo, it's just not grouping to compeye with but for hunting 200 yards and in is ready to go

Dave, I didn't knew anyone could outgrow 30-30 😮 I would also consider running some spired projectiles down there to confirm ammo as the problem. The rifle even after rebuild could have some tolerances slightly off. Looking forward to see if your handloads group better.

That surplus is PPU (nny) serbian made military ammo, 196gr BT very good stuff

I would recommend 180 grain and more. 197 grain where the most used in Europe after WWII.

Good Morning Dave! Nice looking rifle!! I 've got an M48 also my is still in it's stock form. Love that stock on your son's, what brand is it? last time I shot mine, the butt plate got my aim pit smashed into the shooting bench! I got a nice bruise on my shoulder. I'd love to change my stock out!!!

They normally shoot 180 gr Bullet's and heavier good. 197 gr was the most popular in Europe. Copper can be lighter.

I would try some different factory ammo, first. There are a couple of imported brands that are less $teep than big green, which used to be bargain ammo in the day, and you could see if it would like them better.

Due to the insanely downgraded SAAMI spec for.this cartridge in the USA i suspect it is the ammo. I advise trying some euro spec ammo instead or.just hand load to CIP specs.

Just a bit of scope info. If comparing a 30mm tube to a 1" tube the larger diameter tube doesn't increase the amount of light. What a larger tube does allow is a greater amount of adjustment range. The more adjustment range you have means the farther you can dial your turrets before running out of clicks. Thanks for the video.

I've had my eight millimeter mouser since nineteen eighty seven. Fortunately And unfortunately , Mine is a total custom rifle. I only wish I had it's twin brother and it's original condition mill serp.
