Remington 700LR S/S in 300 Winchester magnum

Hey dudes!

Winter sux but don't let the short days and cold weather stop you getting out and testing your gear!

Ive started a series of modifications on a out of the box Remington 700LR in 300wm.

For most this will be a series confirming what you already know through your own experences but for others some of it may come as a surprise.

Mods will be carried out which will effect the handling usability and accuracy but rather than do the modifications all at once we will do things one at a time and shoot the rig with the same loads at the same range with the same shooter after every change.

Any and all questions and suggestions - go right ahead.

cheers!!

Watching with interest and a great concept for newer rifle owners.

Haha... yes but you can't fit 300 win mag in a Tikka without modification so...

I guess I have the first chapter of parts? those bits directly related to prone shooting accuracy.

Im wondering how far to go .. experience tells me that I will reach the limit of prone shooting accuracy pretty fast... so you'll probably see that within the next stage or so...

But like bench rest shooting - prone shooting from a set position has very little to do with making hits at random ranges in field conditions, I think that is where it may get interesting as there are so many add ons and system "enhancements" that can be used however measuring the gains or effects of these changes could be hard.-

-I think the key will be to design a short course of 5 Targets or so then run the course with each change.

Then after each run rating the results on overall time and accuracy... heck maybe even heart rate... we shall see.

Also I should say if anyone is ever in the wellington area and wants to get involved let me know!

It looked like the groups were worse after you added the timney trigger. Why do you think that would have been? I have the chance to get a Jewel trigger off a mate and at present I have a standard Remington 700 trigger. Do you think there is that much difference to justify the change?

:thumbsup: Cheers @Pengy :thumbsup:

Very interesting series, I'll watch it with interest. I find it challenging to shoot these more powerful rifles consistently well for extended courses of fire (I'm shooting a 7x64, so just a smidge under 7mm Rem mag power). In the video you "shuffle" a lot between shots, would it be better to get and check your position once if you can and then shoot the whole course? I'm not trying to be a smart-arse (I know from your other video's you're capable of very good marksmanship) so if you're doing things deliberately I'd like to know.

haha indeed- its not that they were much worse but more the fact there was no improvement...
but as I said in the clip - I have shot a lot of standard triggers and have learned to mitigate the effects of them while shooting prone off bags.

In the field where the shooting positions are so varying that old trigger would see me pull shots wide I can guarantee it.

Jewel triggers are generally awesome you will love it... that being said I can't really fault the Timney ... nice wide blade aswel.

Yeah to be honest the recoil is why the groups are not great.

After one shot the rifle recoils and slides too far down the rear bag because of the slanted underside... if I simply slid the rifle forward there will not be enough pressure vertically on the rear bag and if I took the shot it will undoubtedly hit high.

The more recoil your dealing with the more crucial your pressure and body/rifle connection becomes (in my experience)

Have you thought of a suppressor or brake? I was thinking of getting one of those stainless longranges but got a second hand 700 ( unsure of model) that came with a suppressor and its shoots beautifully with bugger all recoil.

Gota do both dont ya ;)

Dudes!! next stage is up!!!!

Dude in the first vid definitely needed a roasting about his get up, no clubs round there mate.

Great stuff!

thanks for sharing - great info for some one starting off wanting to improve their game. I like the simple stepwise approach. One suggestion from the first video - safety wise for young hunters viewing this - I'd recommend having the bolt open when waving the rifle around. Found myself ducking a few times :thumbsup:

Very nice Doc especially watching HSS being used on a lathe.
Mitch is a good helpful man.

That can looks the biz, what does it weight?

Ha ha my mate rides FMX and plugs that jerky all the time :D

it looke like to me ( correct me if i am wrong here ) that cutting a new crown had the most improvement, the suppressor just made it nicer to shoot . . . good videos i will watch with much interest.

ditto the nice look can . . . that burr on the front not so much tho.

cheers R.

What model timney trigger is it?

Does it have top safety and bolt release on trigger?

Cheers

He's clearly in the wrong post code dressed like that.

Haha Ben, epic roasting about the outfit in the 1st vid, too cruel :-)

Um... na man just watch the clip again maybe.

I shoot groups re-crowned then walk forward fit the suppressor then shoot the next lot of groups.

it actually went down like this ...

Dude - "hey man I'm in welly what you up to?"

Doc - "cool dude I'm just about to go shooting ill pick you up in a tick..."

Dude - ..."ah its pretty cold and I don't have appropriate gear man.."

Doc - "Dude! the range is pretty much a golf course and you can just wear the liner from my old jacket - no ones gonna see you dude, stop being a pussy..."

:ORLY:

cheers . . my mistake, thats what happens when i try to watch the vid while doing something else at the same time.

that is a fantastic improvement with the suppressor on . . is that what you would expect because its a Big kicker of a cartridge ?

I think suppressed rifles shoot well for a number of reasons -
actually I will probably stop and do a video summary before carrying on with the next lot of mods.

I was surprised to see how much difference the suppressor made, biggest improvement by far. The recrown looked like a small gain at best. I have moved to doing all load dev without suppressor or brakes to avoid excessive carbon build up and get down to 0.3 - 0.6 Moa in pretty much all cases, even with some light weight rigs (6 lbs bare rifle).
then fine tune final load with suppressor for poi. Have not noticed a big improvement in groupings l guess I must have developed a fair degree of recoil tolerance :pacman:

I have a good target showing suppressed (and chrony attached) vs non suppressed on same rifle with same load but I don't want to clutter up the thread or drag it off on a tangent.
I am watching this thread with interest, are you intending to also true the action?? @Dr. Watson

Hey Doc, cool video series. Couple of questions, and forgive me if they have already been answered within the thread. What powder are you using for the load? Also, whats with the shooting done in the dark? Is that just due to time constraints or are you purposely wanting to shoot it in the dark/cold?

I would guess it's mainly due to time constraints. The targets are well lit up and it's also pretty still at that time of night too. Also it looks cool?

if I get the projectile I want, going the speed I want, seated at a depth that runs right out of the mag and shoots like this...

Attachment 72419

Generally from here all I'll keep an eye on is fauling and retained accuracy- I will only go back to the drawing board if one of those becomes a problem.

Na man ask away - the powder is R17

As for why the dark - I start at 630 and work in an office 9 hours a day - in winter it's pretty much always dark by the time I'm done.

So I just started to shoot at night - it's actually kinda nice.

Maybe a video showing the effects of 190 Berger @3050 on possum?

Thanks for taking the time to make the video and posting dr.......

Would you expect similar accuracy results if you used a muzzle brake as opposed to the suppressor???

An excellent question - we will do that in part 5 so you can decide for yourself!!

Sweet, whens it out? :D tonight?

I have one of those cans, turned up tonight with my new 300wm - the first thing I did was weigh it = 352 grams
