haha mike i almost ordered a rifle in 600 OK instead of the 505 Gibbs. AHR offers a 600 OK for only $300 more then the Gibbs. the one thing that stopped me was the weight of the rifle. the idea of packing around a 14+ pound rifle while hunting didnt sound appealing.

that doesnt mean the 600 OK is out of the question in the future though.

nope matt will come and chastise you now, as i was for mentioning 9.3x62...........

He will make an exception for a new guy if he thinks that he can use the guys 9.3 as a gateway rifle to get a guy hooked on the big stuff.

He knew you were just trolling!

Oudh! That is a nasty slap.

Matt I've adapted a very open stance when shooting the bigger calibers. What I mean with this is that most people shoot in a very closed position when firing their guns where their left shoulder points at their target if it is a right handed shooter . When the refile recoils their shoulder goes back but their head stays in the same position causing a lot of scope cuts. With a more open stance recoil is taken up by your whole upper body including the head that moves back. Riding and managing the recoil to a much greater effect. All my DG rifles are scoped even the 505 Gibbs and touch wood I've never been kissed. I do hold the fore end firmly though and I feel that this also takes up some recoil and helps my recovery time on getting back on target. It also makes my reloading easer and I guess faster.

I also use a rather thick ammo poach on my stock to raise my face for better alignment to the scope. I admit this has more to do with Rugers stock design not having a cheek piece. Something I must still rectify with custom stocks.

only rifle to ever touch me with its scope is Bob's 505 Gibbs. but that didnt become an issue until i got velocities around 2400+fps with a 525gr bullet, if kept at 2300fps or less its not an issue. fortunately the scope did not cut me because it has a nice rubber pad around the eye piece. if it were my rifle i would have moved the scope further forward and that would solve the issue.

as for the 9.3mm cartridges... they have a place, it just isnt here. dont get me wrong i love the 9.3's and would love a double in 9.3x74R but i consider them to be medium bore guns (and so does this forum). i typically consider the .375" to be a "gate way" caliber between medium bores and large bores but in reality its a medium bore as well. some even consider the .400"-.423" cartridges to even be medium bores but i would say that in modern times if the caliber starts with a .4 then its a large bore rifle.

my personal take on caliber classification:

micro bore: under .220"
small bore: .220"-.320"
medium bore: .320"-.400"
large bore: .400"-.510"
ultra bore: over .510"

seeing as this section of the forum is .375" and up, im not going to discourage members from discussing .375" caliber guns here. but i do ask that we keep it to .375" and up to keep things on topic which is mainly heavy recoiling guns slinging huge amounts of lead.

enough rambling from me!

Wouter that is some good advice I had to learn the hard way - never been touched by a scope (thankfully) and all mine are scoped as well but "riding the recoil" by adapting your stance does make it a lot more manageable and fun to shoot to the extent that I can run 50 rounds of Lott without any issue , although I can feel it in the shoulder the next morning (Deep muscle massage for men ).

Benching with the big boys is a different story! I ended up building my own portable bench as being 6 foot 6 I end up almost bent over the rifle if the bench seat does not adjust , which from a recoil perspective is as close to a religious experience as I want to get !! The same applies off the bench I believe - sit more sqaure to rifle and at least allow the upper body to ride with the recoil if possible.......still easier said than done though but so be it.

 

[matt85]

yer a better man then me, im not brave enough to bench my large bore rifles. one of these days i need to build a standing rest though.

just like the Lott, the 505 Gibbs is actually pretty easy to shoot once you get used to the recoil. i like to limit my shooting to 30 rounds per range session to avoid that sore shoulder the next day. however, i have to make sure i dont bring more then 30 cartridges to the range because these things are so fun to shoot i tend to get caught up and will shoot up all my ammunition which is rough on both the shoulder and the wallet.

I use a sandbag between rifle and shoulder when I do bench work with the big boys. It is a small and thin bag that normally gets used as a support for your elbow at the bench. This takes basically all the venom out of the gun and helps you not to develop the dreadful flinch. I know of people attaching weights on the barrel band swivel but this is something I would personally not consider due to the fact that I am very sensitive to the accuracy of my loads and this can interfere with this. Even though it is a big bore it must be accurate.

My chair at my bench can also adjust for height for I was also produced over a long weekend. This is very valid point you make in handling and riding recoil from a bench.

Matt it is so true what you say about getting carried away. These days I really try to practice to a plan. I try to do some shooting of my shooting sticks I use in my hunts at small targets taking my time. Then I always end of in off-hand practice at a set time to try and increase the adrenaline levels to simulate a charge or follow up shots on a feeing target. The smile I normally carry after such a session it very comparable to the one that must have covered my face after my first experience of a different encounter in a rowing boat with a 18 year old varsity bombshell.

So do most of you guys just take just one of the big boys out at a time or several. If you take several do you normal start with the biggest or the smallest. Me personally I very seldom go shooting alone so I just shoot whatever isn't being used.

 

[matt85]

Amon458, it depends on what im shooting but i usually take two rifles to the range. this is especially true if im shooting one very expensive to feed gun like a 505 Gibbs. ill bring a less expensive (to feed) gun along to keep me entertained after i run out of the big cartridges. in most cases this is a 416 RM or my newest addition a 450 NE 3.25".

i usually shoot the biggest gun first but thats really just because i like to shoot big guns...

-matt

 

[Bullthrower338]

How did I miss the 450 NE Matt? I must have been reading through under the influence of Johnny Walker to miss this

 

[IdaRam]

Yeah Matt, I seem to missed this important detail as well You holding out on us bro? Major party foul

 

[matt85]

did i say 450 NE...

i bought a 450 NE 3.25" double rifle in AK while at the last double rifle shoot. its nothing fancy just a Saur 12g shotgun that a gunsmith converted to 450 NE 3.25". the price was good and i figured it would fill the gap between my 416 RM and my 505 Gibbs. im still tinkering with loads to find one that regulates properly and the front sight didnt make it threw shipping so its a work in progress.

ive got a new front sight and once ive got it installed ill post a picture of the rifle.

-matt

 

[matt85]

i should also mention that my friends rifle in 585 HE showed up monday. the rifle is a pretty simple single shot gun that is far from finished (no blueing or wood finish and still needs sanding). but we were expecting that as the price reflected the lack of finishing. seeing as my friend wants to run a 750gr bullet at over 2300fps we want the gun to be as heavy as possible. it currently weighs 17 pounds but we will likely add a few pounds to the stock to improve the balance and help deal with the massive recoil.

the plan is to take it out this weekend and try out some cartridges.

[IdaRam]

Sounds like it's going to be a good weekend Looking forward to pics of your and your buddy's latest additions

Might be time for another video Matt!

 

[matt85]

a video would be great... problem is my camera didnt survive its trip to Africa and is currently being repaired.

matt did your photos survive?

 

[matt85]

matt did your photos survive?

the ones I took before the camera bit the dust did. the front of the camera around the lens was bent on one of the morning bakkie rides. I made the stupid decision to store an extra battery in the pouch with the camera and it was this battery that damaged the camera.
