I read ti's statement in Magnum magazine " Remember that shooting small groups from a solid bench-rest position may satisfy you, but it can also give you false confidence in your shooting ability. Your biggest grouping (not the smallest) from a field shooting position at any given distance...

Hi all, had an interesting observation today. I bought a brno .22 that was made in 1948 and have been fixing it up. I was struggling to get it to group and so I started cleaning the barrel with solvents and bronze brushing. I probably soaked solvent 15 times for an hour or two each time. I...

Hi All, quick question for those with experience on scout scopes- can you set them up with normal eye relief and does that have any negatives. I am looking at a vortex crossfire 2 scout 2-7x 32 to fit on my Cz 550 30- 06. I will set it up for max eye relief but it will not be a traditional...

Hi All, Just asking if anyone would be part of a hunting video series like TIA or something similar on youtube. There is no money to be made from youtube revenue because it is hunting but I see that many people like to share their stories and it helps publicize hunting and videographers. I am...

Hi All, Came across a video that tackles this old battleground. Give it a look and lets see if it sparks some discussion. If you search Youtube for Thesylvanshadow, he posted a practical video called Energy vs momentum Part 2. He uses a pcp airgun to explore velocity vs bullet mass with regards...

So here is a question I had- how many people wipe down scope mounts and the action dovetails with oil when they mounts scopes. And if you dont oil the dovetails, how do you deal with rust prevention ? I had my CZ 550 apart -had to get the barrel 'fingerprinted' by the Police firearms section as...

Just a general discussion about how popular it is to have your hunt videoed by a pro. Do you have any specific preferences in the process. Do you request 4K video or normal HD ? Do you talk in the video ie like you are presenting your own hunting show or do you just want a record of the hunt ?

So I was thinking, if you use something like electrical switch cleaner spray to get all the oil out of the bore before going hunting, does it reduce the first shot flyer ?

Saw an interesting disscussion on Facebook. A guy was saying he had primers on unfired cartridges backing out or becoming proud of the base after a flight. He was wondering if it was due to pressure changes during the flight. This was then followed by a comment that compressed loads can also do...

Hi all, I bought a second hand rifle and took the scope off. I saw all sorts of things that I would change but maybe I am being a bit ocd. Vertical reticle was perfect when checked with a plumbline. 1. Front mount is at a slight angle to the scope. Surely this will bend the scope tube when you...

Hi All, Looking at Quickload and Gordons Reloading tool as well as some reloading data from my range sessions, I have seen a pattern developing and I wanted to start a discussion. First off I know it is dangerous to assume, no hard and fast rules etc. I just see an interesting trend. So for...

Hi All, Just trying to tap into the collective wisdom of the forum. I bought a 3006 recently. Rumor has it that CZ 550 shoots quite well (or maybe shoots better than other manufacturers) with the 220 gr bullets. I believe that the CZ has a slightly faster twist rate than standard and so is...

Hi all, I have to choose between a Mauser 7x57 approx. 20 or 30 years old but in good condition and a 7x64 Brno with a hair trigger in fantastic condition. The brno is an extra $200. What do you guys think ?

Hi All, I ask the learned gun nuts on the forum if CZ 550 mounts are the same as Brno/CZ .22 mounts. Initial investigation indicates they are the same size -17 mm. Seems possible. I just bought a .22 but will have to go through licensing procedure before I have it in my hands and I am trying to...

Hi all, anyone out there have experience with rust blueing ? I have a few questions: 1. I am thinking of fixing some rusty worn areas of factory blueing with rust blue.anyone done that and got pictures ? 2. Normal procedure is rust/boil/card 4 or more times. Can you rust/card over and over...

Hi All, Anyone recommend a good videographer for producing hunting videos ?

Hi All, Touchy subject-Please don't lay into PH's or clients, but how do you guys see the roles of client and PH in a wounded dangerous game animal follow up? My thoughts are that a clients role is to finish what he started. He should stand beside the PH and attempt to kill the animal as fast...

Hi All, Little bit of Fun at our local range on Sunday. About 14 competitors- 6 shots to count. First video is the course. Basic idea is first shot is the target to the right of the 'charging lion'. That starts the 'lion' charging for you second shot. Then two targets to the left-reload and two...

Hi all, Some theory questions to the experienced reloaders: When choosing powder for a certain bullet/cartridge combination, what do you look for ? So I have Quickload data and Gordons Relaoding Tool freeware. So looking for a certain velocity, you can use different powders. Some produce the...

Hi All, anyone have load data for 458 Lott wit Peregrine 500 gr VRG-2 solids and VRG3 softs with Vihtavuori N550 powder or maybe willing to run a Quickload for me ? Also anyone used Gordons Reloading Tool ? Freeware copy of Quickload it seems. If I can get a Quickload file, I will compare it to...

Hi All. Anyone have actual data where the bullet was on target but didn't make it to the target- ie it under penetrated ? I am talking bullets on the perfect line for the brain or heart/lungs and they either underpenetrated or turned/tumbled and so the animal was wounded. Specifically, the...

Hi all, I have some thoughts on lubrication of dangerous game rifles and would like to know what everyone does with their rifle- maybe mention if you are a PH or if you are a client. I do kids camps in the bush so plenty of walking/ dust and sweat but little action. My basic thinking is to have...

I am really struggling to find facts and this really bothers me. I have searched the internet and I find conflicting reports and very little scientific data. So far I have found Charlie Haley's tests of round nose fmj vs round nose monolithics. He give almost identical results in a very...

So lockdown fever struck, even though I am still working during the week but less hours. So I have tackled a few jobs around the house and a few just for pleasure. So I started one evening sanding off the finish on my CZ 550. Didnt have any paint remover and hardware shops are shut so I bit the...

Hi All, While doing some research, I noticed some differences between a factory chamber and a reamed from Win Mag chamber. This would impact developed hand loads and is something for hand loaders to be aware of and take extra care when using other peoples loads. If you look at the SAAMI picture...

Hi All, The debate has raged about the 458 win mag for years and I just wanted to cut through the bull doo doo and try to compare some well loved calibres and the math behind their reputation. In the picture below, I have put down some facts and figures that are used to compare ballistics...

Hi all, quick question. Does anyone know what weight trigger pull your DG rifle has and how much sear overlap ? I tend to err on the side of caution and safety, mine is about 3,5 lbs and the sear has 1,5 mm before it trips. My thoughts on sear overlap is that a super safe trigger will have creep...

Hi All, I helped out with the Pro Hunters and Guides shooting tests this weekend. The other thread, https://www.africahunting.com/threads/rifle-lessons-learned-from-the-zimbabwe-professional-hunter-proficiency-exam.2604, has had a lot of interest so I thought I would post my experiences and...

I wanted to put down my thoughts,opinions and actions that I used to tune a CZ 550 in 458 win mag, from what I understand, that caliber is particularly difficult being short and fat. I searched the internet and there was not much to be found. Duane Wiebe has posted a brief process on another...

Hi All, Just thought I would share my experiment in smoothing out a brand new CZ 550 in .458 Win Mag.Please note this is what I did, it is not intended as a definitive how to guide, use this information at your own risk ! I may add or change things as I think about them. I searched the internet...

Hi all, has anyone put 458 win mag factory ammo over a chrono ? It would be great if you gave some actual readings with an idea of your setup ie rifle make, barrel length, ammo make and bullet weight. I am mainly interested in solids but please let me know what you know!

Hi all, Some discussion on the thread about Zimbabwe PH tests has got me thinking and i did some google research but cannot find the answer. Perhaps someone can help. In the article, Don Heath says the Ruger action ejector does not seem to spring back quick enough to eject if the action is...
