20BR,20PPC question???????

[Phil]

OK.............I already own a .20VT and a Tac.20 so i have a little experience with the .20`s...

My question is........Approximately how many rounds will i be able to fire form either of these guns before i start to barrel fowl and lose accuracy??????

I`m thinking that i NEED another .20 and i`m leaning twords the 20PPC for ease of necking down,one step) and am curious how much will i be able to shoot it before i need to clean it.....

This gun is a varmint gun only using 40gr. max wt. bullets..

Oh yeah........I NEVER clean my gun`s till i`m done shooting for the day...

phil I have read over your post a few times and think thear are a lot of variables in all of the questions.

#1 how many rounds???? well to ME That normaly means what qualitiy of brl and how it was broken in even a bad brl broken in properly will cach and fowl faster than a good brl broken in badly.
I find the faster the twist and the harder tou push them the sooner thay nead cleaned
I have 1 exseption it is a stock sav 204 witch will foul out in 10 to 15 rounds but my 20 250 9 twist will go about 30 to 40 then a 20 classic 12 twist will go about 150 Most I have shot a 1 siting 20 ack hornet has had in the naborhoud of 300 in a day without any notisable problems.
20 br with a 12 twist used brl beter than my 20-250 with a premiom brl

all you can do is build it shoot it and see? Hope this is soom help

My 20BR 1 in 9 went about 20 rounds before groups started to open up, new barrel though.
