bewsh Posted June 18, 2015 Report Share Posted June 18, 2015 just swapped a BRNO .222 for a Sako S491 with the above OEM length barrel BRNO shot everything extremely well with the same twist 52gr Amax over 22.6gr N133 60gr Soft Points over 20.8gr N133 50gr VMax and Nosler BT's I have tried to get the Amax to shoot in the Sako and I am getting 4-7" groups with charge ranges from 22gr to 23.2gr!! the 60gr by contrast is touching holes with one maybe two around 1/14-1/2" off using the exact same load I used in the BRNO in all my years of chucking stuff through a .222 I have never seen groups that big from any combination am going to go back and try the 21.1-22gr range but will be gobsmacked if I have to drop that low and that the groups drop by 7"! anyone using them?

247sniper Posted June 18, 2015 Report Share Posted June 18, 2015 Why didn't he previous Sako owner get rid off it??? Link to comment Share on other sites More sharing options...
bewsh Posted June 18, 2015 Author Report Share Posted June 18, 2015 sorry am not sure what that means. the rifle is very clean and barely used no idea why it was sold but the accuracy with 60gr makes me think it had little to do with its abilities generally Link to comment Share on other sites More sharing options...
happyhunter Posted June 18, 2015 Report Share Posted June 18, 2015 If you carn't get them to work feel free to pack them up and post them down to me.... How did that Parker hale come on in the end? Link to comment Share on other sites More sharing options...
bewsh Posted June 18, 2015 Author Report Share Posted June 18, 2015 I think they are tumbling.. 60gr holes: 2in1 52gr holes:: note side splash of paper and less than round holes Link to comment Share on other sites More sharing options...
John MH Posted June 18, 2015 Report Share Posted June 18, 2015 Are they a new batch of 52 grain A-Max? Link to comment Share on other sites More sharing options...
baldie Posted June 18, 2015 Report Share Posted June 18, 2015 The 53 grain V-max is renowned for not shooting in a 1 in 14" twist. If a customer brings a rebarrel in either 22-250 or .222 , its the first question I ask. "Do you want to use the 53 grain V-max ? " I would guess the 52 grain is the same. Its not the weight, its the overall bearing surface of the bullet. They need a 1 in 12" Link to comment Share on other sites More sharing options...
blackburnbuccaneer Posted June 18, 2015 Report Share Posted June 18, 2015 I have used these bullets in a 1 in 14" .222 BRNO Fox and they worked pretty well. At about 3050 fps they were grouping about 1" at 100y which is typical for this rifle although it does shoot a bit better with Nosler BT's.

bewsh Posted June 18, 2015 Author Report Share Posted June 18, 2015 I just chopped in my BRNO fox for this Sako previously I was shooting 52gr Amax into 1/4-1/2" groups all day long over 22.6gr N133 same 1:14" twist not a nice condition barrel either! never tried the 53gr but did try the 60gr using the same 20.8gr N133 load I use for flat base 60gr Soft points they were Ok but I didnt go any further with the load and went back to Amax as they were cheaper and arrived in the post! very strange am going to try and slow them right down see if that makes a difference don't really want a sub 3000fps load for 50's but if it is the only thing that works then so be it!

gunner Posted June 22, 2015 Report Share Posted June 22, 2015 Im sure my friends t3 lite has a 1-14 and he shoots them very well , but then hees moved to 40s sbk because he struggles to get the Amaxs . Link to comment Share on other sites More sharing options...
bewsh Posted June 22, 2015 Author Report Share Posted June 22, 2015 may have some for sale!! I did a twist measurement today and I also measured the chamber three twist measurements taken between 14.5 and 15" per full twist....not 14:1 Max OAL/ogive on lands for: I am thinking it may be a bearing surface issue. 60gr SP vs 52gr Amax 52gr Amax vs 60gr Vmax http://i40.photobucket.com/albums/e221/bewsh/HSF/IMG_2691_zpshrvmxrtm.jpg 60gr SP is 54.6mm (2.149") (puts my loads at 19 thou off the lands...give or take my measuring tolerance)52gr AMax is 57.8mm (2.275") I have also loaded up another batch of:-AMax starting at 20.8gr through 21.8gr (to see if I can stabilise them at all)-60gr SP at 20.8gr starting from 54.1mm through 54.6mm in 0.1mm increments to see if I can improve on the groups (am perfectly happy with them to be honest but it will serve to prove a point - also the last of my 60gr Vmax to see if a flat base long bearing surface makes a difference will shall see!

Big Al Posted October 17, 2015 Report Share Posted October 17, 2015 What happened in the end Bewsh? Link to comment Share on other sites More sharing options...
bewsh Posted October 21, 2015 Author Report Share Posted October 21, 2015 I sold 400 52gr Amax!! pulling the tips and shortening the bullet made a world of difference 4-5" groups down to 1", same load literally just shot 5, pulled the tips on another 5 and shot them whizzed through these tipless ones quickly so group is strung out, actually shot better than this compared to same bullet with tips two missed the board low! moved onto scierra 45gr flat base for foxes now... annoying that it is so fussy being a nice rilfe Link to comment Share on other sites More sharing options...
Big Al Posted October 21, 2015 Report Share Posted October 21, 2015 Thanks bewsh, Im glad I found this thread last week. I was about to try some 52r Amax in my Sako 75 and I think this thread saved me a lot of hassle. I opted for 40gr Sierra Blitzkings instead over N133 with very good results.

Al, did you have to play much with seating depths to get those groups? I'll be starting to reload for my .222 in the near future, so I'm keeping a keen eye on any .222 threads st the minute.

I'll be starting to reload for my .222 in the near future, so I'm keeping a keen eye on any .222 threads st the minute. No, I started 0.015" away from the lands and hit lucky, then again a few people have told me the .222 is a very easy round to load for, having never owned one I can't really verify this beyond this one example. Of the five powder charges I selected four of them shot sub 1/2". I plan to chop the barrel soon and will most likely use a faster powder so will know better once Ive developed another couple of loads. I did this one before chopping just to verify that the rifle was worth the extra effort/expense, looks like it was Link to comment Share on other sites More sharing options...
