45-70 twist rate
« on: September 26, 2011, 03:16:21 PM »
 
    tried some 300 gr rem in my enfield 45-70 and they will not stablize. 1 raged hole for 5 rounds at 50 yrds barely hitting the paper and keyholing at 100      tight patched the bore and got a 1 in 21.5' twist    what will that stablize properly    i was having no problems with rem 405 and think i will go back to them

The origional twist for the trapdoor springfield was I believe 1x22. So it looks like you are in the ballpark. Frank

Give the 405 gr. bullets a try.  Some friends of mine who shoot BPC like the 500 gr., but they're rifeling is more like 1:18.  My rifle is 1:20 and it likes the 405's.

Not sure what an enfeild 45-70 is, but the twist will certainly work with 300 gr bullets. If you're getting keyholes it's most likely because the bullets are to small for the bore.
 Twists from 18-20 inches work fine with bullets to 500+ grs, slower than the 20 twist and the heavier bullets may start having trouble.

In the 1920's "sheeple" was a term coined by the National Socialist Party in Germany to describe people that would not vote for Hitler. In the 1930's they held Hitler as the only one that would bring pride back to Germany and bring the budget and economy back.....
