Hi guys I have just acquired a place to go goat shooting with large numbers so are looking at shortening my 243 barrel to 20inches and have been looking at a DPT modular suppressor I think being able to clean it would be good as am expecting to be firing a large number of rounds over a period of time & was wondering if anyone has experience with a 20 inch barrel on a 243 and also the DPT suppressors Thanks for any reply's

Hi Brendon
How long is your barrel now?
The 243 relies on velocity heavily (refer to the knowledgebase) by shortening your barrel you will hinder it to appoint you can offset it a little with heavier projectiles and faster power.
There's no need to shorten a barrel to fit a suppressor if it is 22 as is you will end up with roughly a 24 inch barrel with suppressor. You will also find the longer barrel will help with noise reduction. I wouldn't be in a hurry to shorten it this can be done later if you find barrel is to long

Darrens suppressors have a plurry good name, have a squizz on fish n hunt forum.
EBRG is great cartridge for goats but as has been said maybe dont cut it back any shorter, sure if its going to be used as mainly a in the tight bush gun the extra length is a pain in the bum( my .270 at 20ish gets carried canless in the tight stuff but can goes on as soon as open ground is reached) if you carry rifle slung across your front on diagonal with offside hand resting on pistol grip you will find it balances nicely regardless of the extra weight/length on the end.
if you want short light rifle for scrub bashing its a great excuse to buy a 2nd one.......works/worked for me LOL

I think its the quickest way to devalue a rifle! keep it standard length and get the end threaded and get one made like I got for my 22LR by Rev Rodge. SUB-SILENT SUPPRESSORS.......... Check them out

here's Video of my 22LR https://www.youtube.com/watch?v=pRIKiK2msls

Re: barrel shortning & suppersors
Yeah Mike thanks for that. I researched and heard that B4 I ordered mine in 2010. Mine works great and he seamed good to deal with? I mean $110 for my suppressor compared to the moon beams others charge its only a tube with spacers and washers threaded at one end.... and like I said it works and his new stuff looks massive! But I didn't want a flash wank piece to show off!!!!! I just asked Rodge for a super quiet short out front over hang (150mm past barrel) suppressor and he gave me what I wanted no bull shit here you go thanks for the work enjoy your product AND Its SOoooo quiet "click shssss whapp!" So for me he's an all right bloke to deal with from my purchasing experience.
So I don't really give a shit what the others say about him! I don't listen to gossip. You don't know if your not there? Talk is cheap actions prove a mans worth. sorry for the rant. The guy didn't do me any harm and that's all I can base my opinion of his service on! A bit like Einsteins theory about basing a fishes intelligence on how well it can climb a tree??? And the "Black eyed Peas" line about how Haters only hate and when you hate you discriminate! So tell me where is the LOVE ? I think maybe the other suppressor makers are sour because he don't charge the big bucks???? But I don't know because I wasn't there and it's really none of my business???? All I know is that I can kill the TOM cat that pissed on my car seat! As its licking its balls on the front lawn and know one hears a thing!!!!! Thanks Rev Rodge.

Re: barrel shortning & suppersors
Hi guys thanks for the reply's so far the main reason for the question was to see the opinions of other people regarding loss of velocity by shortening by a couple of inches I are using a slow burning powder ADI 2213sc getting 3028 fps with 85grain sierra HPBT so could go to a faster powder to condensate shooting mostly goats and fallow deer was wondering what Nathans thoughts were about this it may also be covered in his books I'm waiting to arrive in the next day or two
I were also reading some old posts about stuff and saw Nathan doesn't like the eye relief on the Zeiss scopes was wondering if this is something that they have addressed as the web page says they have 3.54 inch which must be there minimum I compared this to the Sightron at 3.8 to 4 inches its to late for me as its what I've put on mine but being 243its not big in the recoil dept and if I upgrade I don't think I would go above 308
thanks in advance any replies its a great place to see problems and solutions of our sport

Re: barrel shortning & suppersors
ok...you may have gathered Im not a huge fan of EBRGs but reading your intended purpose I will let you know my experience with them on goats.
many years back neighbour and I went out for a bombup he had a .243 and handloads he had made with a "whack a mole"/hand loading kit and I had my .270 with factory 130s
we shot close to a hundred goats before we ran out of ammo (king country late 80s) we were shooting out to about 300yards and the ONLY difference we could see when hit is mine flopped over and his jumped then fell over LMAO.
if you take 300 yard velocity it will be less than your shorter barrel velocity at 200 yards using the 35-50fps per inch loss.
if you red Greg Duleys bushpig articles(hate that term ,it was a ugly Sheilah when I grew up) you will see with carefull reloading you may well gain back the lost speed.
for goats and fallow you shouldnt notice stuff all difference, lets be honest its no different to one brand of factory Vs another, and adding suppressor SHOULD add to the enjoyment as no big loud boom to bugger your hearing or spook the goats just over the rise.
shootem through the shoulders and they wont go anywhere.

.243/twoforfree/EBRG=Ear Burrowing Rat Gun (burrow it far enough into ear and it will kill it)......lmao

LOL that might be why that wild cattle beast I shot at 200 yards the other week went down so fast was a slightly down hill shot and side on so in the ear was perfect it went down so fast it didn't even know it was dead when it left its feet

Re: barrel shortning & suppersors
Hi Brendon, sorry, just playing catch up here as I have been busy with projects. Sorry also for missing your mail.

OK, so you are at 3030fps with 2213sc. If you go to 20" and change to 2209, I think you will be able to work up to 3150-3200fps and have a good load. This barrel length should work OK and by being a bit shorter and fatter, it will be better regarding the potential muzzle thread diameter and the effects of trapped heat. So in conclusion, you should find that with load development, the rifle can be coaxed to exceed current velocities.

The Ziess will work just fine on that rifle.

Please keep in mind what Thomas said. The smaller the bore, the more reliant we are on high velocity as a mechanism of fast killing. You'll notice that trend as you read through the long range cartridges book.
